EMISSION CONTROL INFORMATION

To protect the environment in which we all live, Kawasaki has incorporated crankcase emission (1) and exhaust emission (2) control systems in compliance with applicable regulations of the United States Environmental Protection Agency and California Air Resources Board. Additionally, Kawasaki has incorporated an evaporative emission control system (3) in compliance with applicable regulations of the California Air Resources Board on vehicles sold in California only.

1. Crankcase Emission Control System

This system eliminates the release of cranckcase vapors into the atmosphere. Instead, the vapors are routed through an oil separator to the inlet side of the engine. While the engine is operating, the vapors are drawn into combustion chamber, where they are burned along with the fuel and air supplied by the fuel injection system.

2. Exhaust Emission Control System

This system reduces the amount of pollutants discharged into the atmosphere by the exhaust of this motorcycle. The fuel, ignition, and exhaust systems of this motorcycle have been carefully designed and constructed to ensure an efficient engine with low exhaust pollutant levels.

The exhaust system of this model motorcycle manufactured primarily for sale in California includes a catalytic converter system.

3. Evaporative Emission Control System

Vapors caused by fuel evaporation in the fuel system are not vented into the atmosphere. Instead, fuel vapors are routed into the running engine to be burned, or stored in a canister when the engine is stopped. Liquid fuel is caught by a vapor separator and returned to the fuel tank.

The Clean Air Act, which is the Federal law covering motor vehicle pollution, contains what is commonly referred to as the Act’s "tampering provisions."

"Sec. 203(a) The following acts and the causing thereof are prohibited...

(3)(A) for any person to remove or render inoperative any device or element of design installed on or in a motor vehicle or motor vehicle engine in compliance with regulations under this title prior to its sale and delivery to the ultimate purchaser, or for any manufacturer or dealer knowingly to remove or render inoperative any such device or element of design after such sale and delivery to the ultimate purchaser.

(3)(B) for any person engaged in the business of repairing, servicing, selling, leasing, or trading motor vehicles or motor vehicle engines, or who operates a fleet of motor vehicles knowingly to remove or render inoperative any device or element of design installed on or in a motor vehicle or motor vehicle engine in compliance with regulations under this title following its sale and delivery to the ultimate purchaser..."

NOTE

The phrase "remove or render inoperative any device or element of design" has been generally interpreted as follows:

1. Tampering does not include the temporary removal or rendering inoperative of devices or elements of design in order to perform maintenance.

2. Tampering could include: a.Maladjustment of vehicle components such that the emission standards are exceeded.

b.Use of replacement parts or accessories which adversely affect the performance or durability of the motorcycle.

c.Addition of components or accessories that result in the vehicle exceeding the standards.

d.Permanently removing, disconnecting, or rendering inoperative any component or element of design of the emission control systems.

WE RECOMMEND THAT ALL DEALERS OBSERVE THESE PROVISIONS OF FEDERAL LAW,

THE VIOLATION OF WHICH IS PUNISHABLE BY CIVIL PENALTIES NOT EXCEEDING

$10,000 PER VIOLATION.

TAMPERING WITH NOISE CONTROL SYSTEM PROHIBITED

Federal law prohibits the following acts or the causing thereof: (1) The removal or rendering inoperative by any person other than for purposes of maintenance, repair, or replacement, of any device or element of design incorporated into any new vehicle for the purpose of noise control prior to its sale or delivery to the ultimate purchaser or while it is in use, or (2) the use of the vehicle after such device or element of design has been removed or rendered inoperative by any person.

Among those acts presumed to constitute tampering are the acts listed below:

Replacement of the original exhaust system or muffler with a component not in compliance with Federal regulations.

Removal of the muffler(s) or any internal portion of the muffler(s).

Removal of the air box or air box cover.

Modifications to the muffler(s) or air inlet system by cutting, drilling, or other means if such modifications result in increased noise levels.

1-2 GENERAL INFORMATION

Before Servicing

Before starting to service a motorcycle, careful reading of the applicable section is recommended to eliminate unnecessary work. Photographs, diagrams, notes, cautions, warnings, and detailed descriptions have been included wherever necessary. Nevertheless, even a detailed account has limitations, a certain amount of basic knowledge is also required for successful work.

Especially note the following:

(1) Dirt

Before removal and disassembly, clean the motorcycle. Any dirt entering the engine or other parts will work as an abrasive and shorten the life of the motorcycle. For the same reason, before installing a new part, clean off any dust or metal filings.

(2) Battery Cables

Disconnect the ground (–) cable from the battery before performing any disassembly operations on the motorcycle. This prevents the engine from accidentally turning over while work is being carried out, sparks from being generated while disconnecting the leads from electrical parts, as well as damage to the electrical parts themselves. For reinstallation, first connect the positive cable to the positive (+) terminal of the battery.

(3) Installation, Assembly

Generally, installation or assembly is the reverse of removal or disassembly. But if this Service

Manual has installation or assembly procedures, follow them. Note parts locations and cable, lead, and hose routing during removal or disassembly so they can be installed or assembled in the same way. It is preferable to mark and record the locations and routing as much as possible.

(4) Tightening Sequence

Generally, when installing a part with several bolts, nuts, or screws, start them all in their holes and tighten them to a snug fit. Then tighten them evenly in a cross pattern. This is to avoid distortion of the part and/or causing gas or oil leakage. Conversely when loosening the bolts, nuts, or screws, first loosen all of them by about a quarter turn and then remove them. Where there is a tightening sequence indication in this Service Manual, the bolts, nuts, or screws must be tightened in the order and method indicated.

(5) Torque

When torque values are given in this Service Manual, use them. Either too little or too much torque may lead to serious damage. Use a good quality, reliable torque wrench.

(6) Force

Common sense should dictate how much force is necessary in assembly and disassembly. If a part seems especially difficult to remove or install, stop and examine what may be causing the problem. Whenever tapping is necessary, tap lightly using a wooden or plastic-faced mallet. Use an impact driver for screws (particularly for the removal of screws held by a locking agent) in order to avoid damaging the screw heads.

(7) Edges

Watch for sharp edges, especially during major engine disassembly and assembly. Protect your hands with gloves or a piece of thick cloth when lifting the engine or turning it over.

(8) High-Flash Point Solvent

A high-flash point solvent is recommended to reduce fire danger. A commercial solvent commonly available in North America is Stoddard solvent (generic name). Always follow manufacturer and container directions regarding the use of any solvent.

(9) Gasket, O-ring

Do not reuse a gasket or O-ring once it has been in service. The mating surfaces around the gasket should be free of foreign matter and perfectly smooth to avoid oil or compression leakage.

(10)Liquid Gasket, Non-Permanent Locking Agent

Follow manufacturer’s directions for cleaning and preparing surfaces where these compounds will be used. Apply sparingly. Excessive amounts may block engine oil passages and cause serious damage. An example of non-permanent locking agent commonly available in North America is Loctite Lock’n Seal (Blue).

(11) Press

A part installed using a press or driver, such as a wheel bearing, should first be coated with oil on its outer or inner circumference so that it will go into place smoothly.

GENERAL INFORMATION 1-3

Before Servicing

(12)Ball Bearing and Needle Bearing

Do not remove a ball bearing or a needle bearing unless it is absolutely necessary. Replace any ball or needle bearings that were removed with new ones, as removal generally damages bearings. Install bearings with the marked side facing out applying pressure evenly with a suitable driver. Only press on the race that forms the press fit with the base component to avoid damaging the bearings. This prevents severe stress on the balls or needles and races, and prevent races and balls or needles from being dented. Press a ball bearing until it stops at the stopper in the hole or on the shaft.

(13)Oil Seal and Grease Seal

Replace any oil or grease seals that were removed with new ones, as removal generally damages seals. When pressing in a seal which has manufacturer’s marks, press it in with the marks facing out. Seals should be pressed into place using a suitable driver, which contacts evenly with the side of seal, until the face of the seal is even with the end of the hole. Before a shaft passes through a seal, apply little high temperature grease on the lips to reduce rubber to metal friction.

(14)Circlip, Retaining Ring, and Cotter Pin

Replace any circlips and retaining rings, and cotter pins that were removed with new ones, as removal weakens and deforms them. When installing circlips and retaining rings, take care to compress or expand them only enough to install them and no more.

(15)Lubrication

Engine wear is generally at its maximum while the engine is warming up and before all the rubbing surfaces have an adequate lubricative film. During assembly, oil or grease (whichever is more suitable) should be applied to any rubbing surface which has lost its lubricative film. Old grease and dirty oil should be cleaned off. Deteriorated grease has lost its lubricative quality and may contain abrasive foreign particles.

Don’t use just any oil or grease. Some oils and greases in particular should be used only in certain applications and may be harmful if used in an application for which they are not intended.

This manual makes reference to molybdenum disulfide grease (MoS

2

) and molybdenum disulfide oil in the assembly of certain engine and chassis parts. The molybdenum disulfide oil is a mixture of engine oil and molybdenum disulfide grease with a weight ratio (10 : 1), which can be made in your work shop. Always check manufacturer recommendations before using such special lubricants.

(16)Electrical Leads

All the electrical leads are either single-color or two-color and, with only a few exceptions, must be connected to leads of the same color. On any of the two-color leads there is a greater amount of one color and a lesser amount of a second color, so a two-color lead is identified by first the primary color and then the secondary color. For example, a yellow lead with thin red stripes is referred to as a "yellow/red" lead; it would be a "red/yellow" lead if the colors were reversed to make red the main color.

(17)Replacement Parts

When there is a replacement instruction, replace these parts with new ones every time they are removed. These replacement parts will be damaged or lose their original function once removed.

GENERAL INFORMATION 1-9

Technical Information – KAWASAKI LOW EXHAUST EMISSION SYSTEM

Since the emission regulations become more severe, Kawasaki has adopted a type of simplified

KAWASAKI LOW EXHAUST EMISSION SYSTEM (KLEEN), which have no catalyst protection system, according to each regulation of different countries.

The muffler with built-in catalyst has the same durability as the conventional muffler, however, do not use leaded gasoline and do not coast with the ignition system OFF. Running the engine without ignition damages catalyst.

Refer to the ZX900E Service Manual (Part No. 99924-1255) for more information about the KLEEN

(theory, maintenance, and handling precautions), including the secondary air injection system.

Honeycomb Type Catalytic Converter

The converter is a three-way catalytic converter, and its surface is covered with alumina upon which platinum and rhodium are applied, and has a cylindrical metalic honeycomb structure made by bending a corrugated sheet and a flat sheet of stainless steel into a spiral of increasing diameter. The honeycomb structure is convenient for the catalytic converter because it has a large surface area but small size to react effectively and has low exhaust resistance. In addition, its inherent strength helps resist vibration, and has simple structure welded directly on the silencer.

Generally, the temperature of the exhaust gas must be higher than activation temperature, so the converters are installed in the exhaust manifold rear end where the temperature of exhaust gas is still high. And, the converters will be activated even under low load conditions.

After the exhaust gas is diluted with the secondary air injection, the catalytic converter works well because of rich oxygen to reduce CO, HC, and NO x

. Accordingly, we can keep the exhaust gas emission within regulation.

This type of converter works more efficiently as a three-way catalytic converter to reduce CO, HC, and NO x than the pipe type catalytic converter because of its more and denser catalysts.

1-12 GENERAL INFORMATION

Technical Information – Monocoque Frame

Why a monocoque? Like all breakthrough innovations, the choice appears quite obvious after the fact. When large-section aluminium spars are wrapped around an already wide, large-displacement in-line Four engine, the resulting package must of necessity be wide. The ZX-12R’s all-aluminium box

-section monocoque chassis eliminates these perimeter spars in favor of a large box section running over the top of the engine.

This frame design surpasses the levels of chassis stiffness and strength associated with conventional aluminium twin-beam frames, but with considerably less breadth. Without the twin beams or other frame elements running around the side of the engine, the fairing can be much narrower, resulting in a much slimmer overall package and significantly better aerodynamics. Further, in a radical departure, the hollow structure also doubles as an airbox for the Ram Air system, eliminating the need for a space-consuming, conventional airbox.

And ultimately, it is the synergy of combining a compact, massively powerful engine with this super stiff and slim chassis structure that explains much of the ZX-12R’s superlative high-speed performance.

All-new frame-integrated Ram Air system adds considerable horsepower in the higher speed ranges.

Monocoque frame allows for the use of perfectly straight, highly efficient inlet ports.

Using the frame backbone as an airbox saves space and creates a very efficient airbox.

Battery mounts inside the frame and the battery cover is a structural element.

Revolutionary new all-aluminum monocoque frame for high rigidity and lightweight.

Huge box section and heat-freated cast steering head/swingarm pivot areas realize an extremely stiff structure and contribute to the ZX-12R’s superb high-speed stability and nimble, super sport handling performance.

By eliminating the dual large-section beams of conventional aluminum frames, this frame design makes possible a much narrower and more compact overall package and greatly improves aerodynamics.

Technical Information – Spark Plug

ZX1200-B1 is equipped with the Kawasaki recommended spark plug (NGK CR9EKPA). By using the Kawasaki recommended spark plug, the idling stability, the fuel consumption improvement, and the maintenance free spark plug is planed.

This spark plug is calculated 3 or 4 times as durable as the usual one (NGK CR9EK).

Feature

1. This spark plug is more superior to the usual one with the ignition for the ignition point protruding.

2. Further, this spark plug is superior to the usual one with the endurance for the Pt alloy [A] covering around the center electrode and for the opposed area improvement of the side electrodes.

Specification

1. Standard Spark Plug CR9EKPA, two side electrodes,

M10 threads

2. Hotter Spark Plug CR8EKPA, two side electrodes, M10 threads

CAUTION

Use only the recommender spark plug. Do not use other spark plug, even though it may fit, because it could cause the engine failure of the idling stability, etc.

Master Key (1 piece)

The master key (colored red) has an inbuilt transponder, containing a master key code. These codes are unique to each key. This code and an additional two user key codes must be registered in the ECU for the system to operate. The master key is necessary when registering user keys and should not be used as the main key to start the motorcycle except in emergencies (loss or damage of user keys). It should be kept in a safe place.

GENERAL INFORMATION 1-15

Technical Information – Immobilizer System (ZX1200-B3)

Transponder (in Keys)

The transponder (made by Texas Instruments, Inc.) has an integrated circuit with a unique code that also calculates data sent by the ECU. When the ignition switch is turned ON, the transponder is excited by the radio wave transmitted from the antenna and then transmits a unique code to the antenna.

User Key (2 pieces)

The user keys (colored black) should be used when riding the motorcycle. These keys have unique codes which differ from the master key. Up to a maximum of five user key codes can be stored by the ECU at any one time. These codes can not be registered to the ECU without firstly registering the master key code.

The antenna transmits a radio wave to excite the transponder, receives the code from the transponder and then transmits the code to the ECU through the amplifier.

Ignition Switch

The ignition switch turns the main circuit ON and OFF.

Amplifier

The amplifier (which is approximately the same size as a match box), amplifies signals from the antenna and the ECU.

ECU

The ECU has the capacity to store a maximum of six key code memories (one master and five user keys). The owner can have a total of five user keys at any one time. The master key memory can not be rewritten after initial registration, whereas the user key memories can be rewritten as necessary.

When the ECU communicates with the transponder, a cipher generator changes the code every time it is used to avoid cloning.

FI Indicator Light

The condition or the failure of the immobilizer system is indicated by various patterns of the FI indicator light blinking.

1-16 GENERAL INFORMATION

Technical Information – Immobilizer System (ZX1200-B3)

Sequence of Operation

1. Turn ON the ignition switch, the ECU, amplifier and antenna start working, and the meter assembly

FI indicator lights up.

2. The transponder excited by radio waves transmitted from the antenna receives the ciphered code from the ECU.

3. The transponder transmits the calculated result from the key’s unique code to the ECU.

4. The ECU compares this with its memorized code, and if they match the engine can start. At this time, the FI indicator in the meter assembly is switched off.

GENERAL INFORMATION 1-17

Torque and Locking Agent

The following tables list the tightening torque for the major fasteners requiring use of a non-permanent locking agent or liquid gasket.

Letters used in the “Remarks” column mean:

L: Apply a non-permanent locking agent to the threads.

M: Apply molybdenum disulfide grease.

MO: Apply molybdenum disulfide oil solution.

O: Apply oil to the threads and seating surface.

S: Tighten the fasteners following the specified sequence.

SS: Apply silicone sealant.

St: Stake the fasteners to prevent loosening.

R: Replacement Parts

The table below, relating tightening torque to thread diameter, lists the basic torque for the bolts and nuts. Use this table for only the bolts and nuts which do not require a specific torque value. All of the values are for use with dry solvent-cleaned threads.

2-6 PERIODIC MAINTENANCE

Periodic Maintenance Procedures

Fuel System (DFI)

Fuel Hose and Connection Inspection

The fuel hoses are designed to be used throughout the motorcycle’s life without any maintenance, however, if the motorcycle is not properly handled, the high pressure inside the fuel line can cause fuel to leak [A] or the hose to burst. Remove the fuel tank (see Fuel System (DFI) chapter) and check the fuel hose.

Replace the fuel hose if any fraying, cracks [B] or bulges

[C] are noticed.

Check that the hoses are securely connected and clamps are tightened correctly.

When installing, route the hoses according to Cable,

Wire, and Hose Routing section in the General Information chapter.

When installing the fuel hoses, avoid sharp bending, kinking, flattening or twisting, and route the fuel hoses with a minimum of bending so that the fuel flow will not be obstructed.

Replace the hose if it has been sharply bent or kinked.

Install the hose clamps in the position shown, and securely tighten the clamp screws to the specified torque.

Check the fuel system for leaks after hose installation.

Fuel Hose [A]

Clamp [B]

Fuel Pipe [C]

18 ∼ 22 mm (0.70

∼ 0.87 in.) [D]

2 ∼ 3 mm (0.08

∼ 0.12 in.) [E]

Fit the fuel hose [A] onto the pipe fully and install the plate clamp [B] beyond the raised rib [C].

1 ∼ 2 mm (0.04

∼ 0.08 in.)

Periodic Maintenance Procedures

Throttle Control System Inspection

Check the throttle grip free play [B].

If the free play is incorrect, adjust the throttle cables.

Throttle Grip Free Play

Standard: 2 ∼ 3 mm (0.08

∼ 0.12 in.)

Check that the throttle grip [A] moves smoothly from full open to close, and the throttle closes quickly and completely in all steering position by the return spring.

If the throttle grip does not return properly, check the throttle cables routing, grip free play, and cable damage. Then lubricate the throttle cable.

Run the engine at the idle speed, and turn the handlebar all the way to the right and left to ensure that the idle speed does not change.

If the idle speed increase, check the throttle cable free play and the cables routing.

Remove the right lower inner cover (see Frame chapter).

Loosen the locknuts.

Screw both throttle cable adjuster to give the throttle grip plenty of play.

Completely close the throttle grip, turn the accelerator cable adjuster [A] to eliminate any cable free play, and tighten the adjuster locknut [B].

Turn the decelerator cable adjuster [C] to adjust the throttle grip free paly to 2 ∼ 3 mm (0.08

∼ 0.12 in.).

Tighten the deaccelerator cable locknut [D] securely.

If the free paly cannot be adjusted with the adjusters, replace the cable.

ZX1200-B1/B2 [E]

PERIODIC MAINTENANCE 2-7

Check the throttle bore for cleanliness as follows:

Set up the fuel tank (see Fuel System (DFI) chapter).

Disconnect the inlet air temperature sensor connector [A].

Remove:

Air Cleaner Cap Bolts [B]

Right and Left Air Cleaner Caps [C]

2-8 PERIODIC MAINTENANCE

Periodic Maintenance Procedures

In accordance with the Periodic Maintenance Chart, check the throttle bores [A] at the butterfly valves [B] and around them for carbon deposits by opening the valves.

If any carbon accumulates, wipe the carbon off the throttle bores around the butterfly valves, using a lint-free cloth

[C] penetrated with high-flash point solvent.

Idle Speed Inspection

Start the engine and warm it up thoroughly.

With the engine idling, turn the handlebar to both sides

[A].

If handlebar movement changes the idle speed, the throttle cables may be improperly adjusted or incorrectly routed, or damaged. Be sure to correct any of these conditions before riding (see Cable Routing Section in

General Information chapter).

WARNING

Operation with improperly adjusted, incorrectly routed, or damaged cables could result in an unsafe riding condition.

Check the idle speed.

If the idle speed is out of specified range, adjust it.

Idle Speed

Standard: 1 000 ±50 r/min (rpm)

Start the engine and warm it up thoroughly.

Turn the adjusting screw [A] until the idle speed is correct.

Open and close the throttle a few times to make sure that the idle speed is within the specified range. Readjust if necessary.

Periodic Maintenance Procedures

Engine Vacuum Synchronization Inspection

ZX1200-B1/B2

NOTE

These procedures are explained on the assumption that the inlet and exhaust system of the engine are in good condition.

Remove the lower inner covers (see Frame chapter).

Set up the fuel tank (see Fuel System (DFI) chapter).

Pull out the vacuum switch valve hose [B] from the air cleaner.

Pull off the three vacuum hoses [A] and rubber cap from the right fittings on the throttle bodies.

CAUTION

Do not remove the atmospheric pressure hose.

Completely close the removed hoses [A] and [B] of the clean air system with the proper plugs.

Completely close the clean air system hole of the air cleaner with the proper plug.

PERIODIC MAINTENANCE 2-9

Start the engine and warm it up thoroughly.

Check the engine speed, using the engine revolution tester [A] for high accuracy.

If the engine speed is out of 1 000 rpm, set the engine speed to

1 000 rpm.

CAUTION

Do not adjust the engine speed by the tachometer in the meter unit.

Connect the vacuum gauge hoses [A] to the right fittings on the throttle bodies.

Connect the vacuum gauge hoses to the vacuum gauge

[B].

Start the engine and left it idle to measure the inlet vacuum.

If the vacuum is incorrect, adjust the synchronization.

Engine Vacuum

Standard: 26 ±1.333 kPa (195 ±10 mmHg) at Idle

Speed 1 000 ±50 r/min (rpm)

2-10 PERIODIC MAINTENANCE

Periodic Maintenance Procedures

Turn the adjusting screw [A] to synchronize the throttle valves.

First synchronize the left two or the right two throttle valves by means of the left and right adjusting screws.

Then synchronize the left two throttle valves and the right two throttle valves using the center adjusting screw.

If the throttle valves synchronization cannot be obtained by using the adjusting screws, check for dirt or blockage, and then check the inlet parts connection.

Special Tool - Pilot Screw Adjuster, C: 57001-1292 [B]

Check the throttle valve synchronization again

NOTE

Do not turn the bypass screws [A] carelessly during throttle valve synchronization. You may cause poor running at low engine speed or irregular throttle sensor output voltage.

Remove the vacuum gauge hoses and install the removed parts.

Check the idle speed.

ZX1200-B3

NOTE

These procedures are explained on the assumption that the inlet and exhaust systems of the engine are in good condition.

Situate the motorcycle so that it is vertical.

Remove the lower inner covers (see Frame chapter).

Set up the fuel tank (see Fuel System (DFI) chapter).

Pull off the vacuum hoses [A] and rubber cap(s) from the right fittings of each throttle body.

Pull off the air switching valve hose [B] from the air cleaner housing.

CAUTION

Do not remove the atmospheric pressure hose.

Plug:

Air Switching Valve Hose [A] and its Air Cleaner Housing

Hole

Periodic Maintenance Procedures

Start the engine and warm it up thoroughly.

Check the idle speed.

Tachometer [A]

Open and close the throttle.

If the idle speed is out of the specified range, adjust it.

CAUTION

Do not measure the idle speed by the tachometer of the meter unit.

PERIODIC MAINTENANCE 2-11

Connect a commercially available vacuum gauge [A] to these right fittings of the throttle body.

While idling the engine, inspect the engine vacuum, using the vacuum gauge.

Engine Vacuum

Standard: 26 ±1.333 kPa (195 ±10 mmHg) at Idle

Speed 1 000 ±50 r/min (rpm)

If any vacuum is not within the specifications, first synchronize the balance of the left (#1, #2) and right (#3, #4) assemblies.

Example:

#1: 165 mmHg

#2: 190 mmHg

#3: 170 mmHg

#4: 200 mmHg

With the engine at the correct idle speed, equalize the lower vacuum of #1 and #2 (example 165 mmHg) to the lower vacuum of #3 and #4 (example 170 mmHg) by turning the center adjusting screw [A].

Special Tool - Pilot Screw Adjuster, C: 57001-1292

Front [B]

NOTE

After adjustment, the final vacuum measurement between the lowest throttle valves may not be 165 mmHg

(in this example). The goal is to have the lower two vacuums between the left (1 and 2) and right (3 and 4) banks be the same.

Open and close the throttle after each measurement and adjust the idle speed as necessary.

Once the throttle valves have been synchronized, inspect the main throttle sensor’s output voltage to ensure proper operation (procedure is at the end of this section).

2-12 PERIODIC MAINTENANCE

Periodic Maintenance Procedures

If any one vacuum measurement is out of the standard measurement after left and right synchronization, turn in the bypass screw [A] until it seat fully but not tightly.

CAUTION

Do not over tighten them. They could be damaged, requiring replacement.

Turn out the bypass screw of the higher vacuum between

#1 and #2 to the lower vacuum.

Turn out the bypass screw of the higher vacuum between

#3 and #4 to the lower vacuum.

Open and close the throttle valves after each measurement and adjust the idle speed as necessary.

Inspect the vacuums as before.

If all vacuums are within the specification, finish the engine vacuum synchronization.

If any vacuum can not be adjusted within the specification, remove the bypass screws #1 ∼ #4 and clean them.

Remove the bypass screw [A], spring [B], washer [C] and

O-ring [D].

Check the bypass screw and its hole for carbon deposits.

If any carbon accumulates, wipe the carbon off the bypass screw and the hole, using a cotton pad penetrated with a high-flash point solvent.

Replace the O-ring with a new one.

Check the tapered portion [E] of the bypass screw for wear or damage.

If the bypass screw is worn or damaged, replace it.

Turn in the bypass screw until it seats fully but not tightly.

Repeat the same procedure for other bypass screws.

Repeat the synchronization.

If the vacuums are correct, check the output voltage of the main throttle sensor (see Output Voltage Inspection of

Periodic Maintenance Procedures

Wheels/Tires

Tire Wear Inspection

As the tire tread wears down, the tire becomes more susceptible to puncture and failure. An accepted estimate is that 90% of all tire failures occur during the last 10% of tread life (90% worn). So it is false economy and unsafe to use the tires until they are bald.

Remove any imbedded stones or other foreign particles from the tread.

Visually inspect the tire for cracks and cuts, replacing the tire in case of damage. Swelling or high spots indicate internal damage, requiring tire replacement.

Measure the tread depth at the center of the tread with a depth gage [A]. Since the tire may wear unevenly, take measurement at several places.

If any measurement is less than the service limit, replace the tire.

Tread Depth

Front:

Standard: 4.0 mm (0.16 in.) (DUNLOP)

Service Limit: 1 mm (0.04 in.)

(AT, CH, DE) 1.6 mm (0.06 in.)

WARNING

If the drive chain wear exceeds the service limit, replace the chain or an unsafe riding condition may result. A chain that breaks or jumps off the sprockets could snag on the engine sprocket or lock the rear wheel, severely damaging the motorcycle and causing it to go out of control.

For safety, use only the standard chain. It is an endless type and should not be cut for installation.

2-28 PERIODIC MAINTENANCE

Periodic Maintenance Procedures

Drive Chain Lubrication

If a special lubricant is not available, a heavy oil such as

SAE 90 is preferred to lighter oil because if will stay on the chain longer and provide better lubrication.

If the chain appears especially dirty, clean it before lubrication.

Oil Applied Grease [A]

O-rings [B]

CAUTION

The O-rings between the side plates seal the lubricant between the pin and the bushing. To avoid damaging the O-rings and resultant loss of lubricant, observe the following rules.

Use only kerosene or diesel oil for cleaning an O

-ring drive chain.

Any other cleaning solution such as gasoline or trichloroethylene will cause deterioration and swelling of the O-ring.

Immediately blow the chain dry with compressed air after cleaning.

Complete cleaning and drying the chain within 10 minutes.

DFI Servicing Precautions

There are a number of important precautions that should be followed servicing the DFI system.

This DFI system is designed to be used with a 12 V battery as its power source. Do not use any other battery except for a 12 V battery as a power source.

Do not reverse the battery cable connections. This will damage the ECU.

To prevent damage to the DFI parts, do not disconnect the battery cables or any other electrical connections when the ignition SW (switch) is on, or while the engine is running.

Take care not to short the leads that are directly connected to the battery positive (+) terminal to the chassis ground.

When charging, remove the battery from the motorcycle.

This is to prevent ECU damage by excessive voltage.

Whenever the DFI electrical connections are to be disconnected, first turn off the ignition SW (switch). Conversely, make sure that all the DFI electrical connections are firmly reconnected before starting the engine.

Do not turn the ignition SW ON while any of the DFI electrical connectors are disconnected. The ECU memorizes service codes.

Do not spray water on the electrical parts, DFI parts, connectors, leads, and wiring.

If a transceiver is installed on the motorcycle, make sure that the operation of the DFI system is not influenced by electric wave radiated from the antenna. Check operation of the system with the engine at idle. Locate the antenna as far as possible away from the ECU.

When any fuel hose is disconnected, do not turn on the ignition SW. Otherwise, the fuel pump will operate and fuel will spout from the fuel hose.

Do not operate the in-tank fuel pump if the pump is completely dry. This is to prevent pump seizure.

Before removing the fuel system parts, blow the outer surfaces of these parts clean with compressed air.

When any fuel hose is disconnected, fuel may spout out by residual pressure in the fuel line. Cover the hose joint with a piece of clean cloth to prevent fuel spillage.

When installing the fuel hoses, avoid sharp bending, kinking, flattening or twisting, and route the fuel hoses with a minimum of bending so that the fuel flow will not be obstructed.

Route the hoses according to Cable, Wire, and Hose

Routing section in the General Information chapter.

DFI Servicing Precautions

Install the hose clamps in the position shown, and securely tighten the clamp bolts to the specified torque.

Check the fuel system for leaks after hose installation.

Fuel Hose [A]

Clamp [B]

Fuel Pipe [C]

Torque - Fuel Hose Clamp Bolts: 1.5 N·m (0.15 kgf·m, 13 in·lb)

To prevent corrosion and deposits in the fuel system, do not add to fuel any fuel antifreeze chemicals.

Replace the fuel hose if it has been sharply bent or kinked.

The fuel hoses are designed to be used through out the motorcycle’s life without any maintenance, however, if the motorcycle is not properly handled, the high pressure inside the fuel line can cause fuel to leak [A] or the hose to burst. Bend and twist the fuel hose while examining it.

Replace the hose if any cracks [B] or bulges [C] are noticed.

FUEL SYSTEM (DFI) 3-41

To maintain the correct fuel/air mixture (F/A), there must be no inlet air leaks in the DFI system. Be sure to install the oil filler plug [A] after filling the engine oil.

Clutch Cover [B]

Torque - Oil Filler Plug: 1.5 N·m (0.15 kgf·m, 13 in·lb)

3-42 FUEL SYSTEM (DFI)

Troubleshooting the DFI System

Outline

When an abnormality in the system occurs, the FI indicator LED (Light Emitting Diode) light goes on to alert the rider on the meter panel. In addition, the condition of the problem is stored in the memory of the ECU (electronic control unit).

With the engine stopped and turned in the self-diagnosis mode, the service code [A] is indicated by the number of times the FI indicator LED light blinks.

When due to a malfunction, the FI indicator LED light remains lit, ask the rider about the conditions [B] under which the problem occurred and try to determine the cause [C].

Don’t rely solely on the DFI self-diagnosis function, use common sense; first conduct a pre-diagnosis inspection, check the ECU for ground and power supply, the fuel line for no fuel leaks, and for correct pressure. The pre-diagnosis items are not indicated by the FI indicator LED light.

Even when the DFI system is operating normally, the FI indicator LED light [A] may light up under strong electrical interference. No remedy needed. Turn the ignition SW

(switch) OFF to stop the indicator light.

When the FI indicator LED light goes on and the motorcycle is brought in for repair, check the service codes.

When the repair has been done, the LED light doesn’t go on. But the service codes stored in memory are not erased to preserve the problem history, and the LED light can display the codes in the self-diagnosis mode. The problem history is referred when solving unstable problems.

Much of the DFI system troubleshooting work consists of confirming continuity of the wiring. The DFI parts are assembled and adjusted with precision, and it is impossible to disassemble or repair them.

When checking the DFI parts, use a digital meter which can be read two decimal place voltage or resistance.

Remove:

Seats (see Frame chapter)

Strage Box (see Frame chapter)

The DFI part connectors have seals, including the ECU.

When measuring the input or output voltage with the connector joined, use the needle adapter set. Insert the needle adapter inside the seal until the needle adapter reaches the terminal (for example, ECU is shown.).

Digital Meter [A]

Connector [B]

Needle Adapter Set [C]

Special Tool - Needle Adapter Set: 57001-1457

CAUTION

Tape the leads to prevent short circuit of the leads.

Troubleshooting the DFI System

After measurement, remove the needle adapters and apply silicone sealant to the seals [A] of the connector [B] for waterproofing.

Silicone Sealant (Kawasaki Bond: 56019-120) - Seals of Connector

FUEL SYSTEM (DFI) 3-43

Always check battery condition before replacing the DFI parts. A fully charged battery is a must for conducting accurate tests of the DFI system.

Trouble may involve one or in some cases all items.

Never replace a defective part without determining what

CAUSED the problem. If the problem was caused by some other item or items, they too must be repaired or

• replaced, or the new replacement part will soon fail again

Measure coil winding resistance when the DFI part is cold

(at room temperature)

Do not adjust or remove the throttle sensor.

Do not directly connect a 12 V battery to a fuel injector.

Insert a resistor (5 ∼ 7 Ω ) or a bulb (12 V × 3 ∼ 3.4 W) in series between the battery and the injector.

The DFI parts have been adjusted and set with precision.

Therefore, they should be handled carefully, never strike sharply, as with a hammer, or allowed to drop on a hard surface. Such a shock to the parts can damage them.

Check wiring and connections from the ECU connector to the suspected faulty DFI parts, using the hand tester

(special tool, analog tester) rather than a digital tester.

Special Tool - Hand Tester: 57001-1394

Make sure all connectors in the circuit are clean and tight, and examine wires for signs of burning, fraying, etc. Deteriorated leads and bad connections can cause reappearance of problems and unstable operation of the DFI system.

If any wiring is deteriorated, replace the wiring.

3-44 FUEL SYSTEM (DFI)

Troubleshooting the DFI System

Pull each connector [A] apart and inspect it for corrosion, dirt, and damage.

If the connector is corroded or dirty, clean it carefully. If it

• is damaged, replace it. Connect the connectors securely.

Check the wiring for continuity.

Use the wiring diagram to find the ends of the lead which is suspected of being a problem.

Connect the hand tester between the ends of the leads.

Set the tester to the × 1 Ω range, and read the tester.

If the tester does not read 0 Ω, the lead is defective. Replace the lead or the main harness or the sub harness.

If both ends of a harness [A] are far apart, ground [B] the one end [C], using a jumper lead [D] and check the continuity between the end [E] and the ground [F]. This enables to check a long harness for continuity. If the harness is open, repair or replace the harness.

When checking a harness [A] for short circuit, open one end [B] and check the continuity between the other end

[C] and ground [D]. If there is continuity, the harness has a short circuit to ground, and it must be repaired or replaced.

Troubleshooting the DFI System

Narrow down suspicious locations by repeating the continuity tests from the ECU connectors.

If no abnormality is found in the wiring or connectors, the

DFI parts are the next likely suspects. Check the part, starting with input and output voltages. However, there is no way to check the ECU itself.

If an abnormality is found, replace the affected DFI part.

If no abnormality is found in the wiring, connectors, and

DFI parts, replace the ECU.

The diagnosis flow chart illustrates the above procedures.

After inspection, be sure to connect all the DFI electrical connectors. Do not turn the ignition SW ON while the DFI electrical connectors and ignition system connectors are disconnected. Otherwise, the ECU memorizes service codes as open circuit.

3-58 FUEL SYSTEM (DFI)

Self-Diagnosis

Self-diagnosis Outline

The self-diagnosis system has three modes and can be switched to another mode by grounding the self-diagnosis indicate terminal [A].

User Mode

The ECU notifies the rider of troubles in DFI system and ignition system by lighting the FI indicator when DFI system and ignition system parts a faulty, and initiates fail-safe function. In case of serious troubles ECU stops the injection/ignition/starter motor operation to prevent battery discharge, and notifies the rider that the engine will no start.

Dealer Mode 1

The FI indicator LED light emits service code(s) to show the problem(s) which the DFI system and ignition system has at the moment of diagnosis.

Dealer Mode 2

The FI indicator light LED emits service code(s) to show the problem(s) which the DFI system and ignition system had in the past.

Self-diagnosis Function

The self-diagnosis indicates problems with the parts, wiring, and ECU in the DFI system and ignition system.

The ECU [C] always monitors each DFI circuit [A] for problems by measuring the voltage [B]. This circuit includes parts [D], and wiring [E].

When the circuit is open (problem), the following are possible problems.

Disconnection [F] in the Parts

Disconnection [G] in the Wiring

Disconnection [H] in the ECU

When the FI indicator indicates a problem, the ECU has the possibility of the problem as well as the parts and the wiring outside the ECU.

Self-Diagnosis

Self-diagnosis Procedures

When a problem occurs with the DFI system and ignition system, the DFI indicator LED light [A] goes on.

NOTE

Use a fully charged battery when conducting self-diagnosis. Otherwise, the LED light blinks very slowly or doesn’t blink.

Keep the display switch grounded during self-diagnosis, with a auxiliary lead.

Remove the strage box (see Frame chapter) and pull the self-diagnosis indicator terminal [G].

Turn on the ignition switch.

Connect an auxiliary a lead [E] for grounding to the selfdiagnosis indicator terminals.

Enter the self-diagnosis dealer mode 1 by grounding

[A] the self-diagnosis indicator terminal to the ground for more than 2 seconds [C], and then keep it grounded continuously [D].

Count the blinks of the LED light to read the service code.

Enter the self-diagnosis dealer mode 2 by repeat opening

[B] and grounding [A] the lead more than five times [F] within 2 seconds [C] after the lead is first grounded, and then keep it grounded continuously [D] for more than 2 seconds.

Count the blinks of the LED light to read the service code.

NOTE

If the self-diagnosis mode is in user mode or dealer mode 1 then you need to enter the dealer mode 2, turn off the ignition switch once.

How to Read Service Codes

Service codes are shown by a series of long or short blinks of the FI indicator LED light as shown below.

Read 10th digit and unit digit as the FI indicator LED light blinks.

When there are a number of problems, all the service codes can be stored and the display will begin starting from the lowest number service code in the numerical order. Then after completing all codes, the display is repeated until the self-diagnosis indicator terminal is open.

If there is no problem, no code is shown.

Repeat blinks [C] or light [B], unlight [A].

For example, if four problems occurred in the order of 12, 21, the service codes are displayed from the lowest number in the order listed.

(12 → 21) → (12 → 21) → · · · (repeated)

If the problem is with the following parts, the ECU cannot memorize these problems, the FI indicator

LED light doesn’t go on, and no service codes can be displayed.

3-66 FUEL SYSTEM (DFI)

Self-Diagnosis

Note:

(1) α – N Method: the DFI control method from medium to heavy engine load. When the engine load is light like at idling or low speed, the ECU determines the injection quantity by calculating from the throttle vacuum (vacuum sensor output voltage) and engine speed (crankshaft sensor output voltage).

This method is called D-J method. As the engine speed increases, and the engine load turns middle to heavy, the ECU determines the injection quantity by calculating from the throttle opening (throttle sensor output voltage) and the engine speed. This method is called α – N method.

* This depends on the number of stopped cylinders.

Throttle Sensor (Service Code 11) (ZX1200-B1/B2)

The throttle sensor is a rotating variable resistor that change output voltage according to throttle operating.

The ECU senses this voltage change and determines fuel injection quantity, and ignition timing according to engine rpm, and throttle opening.

NOTE

The standard voltage marked with an asterisk refers to the value when the voltage reading at the Input Voltafe

Inspection shows 5V exactly.

When the input voltage reading shows other than 5V, derive a voltage range as follows.

Example:

In the case of a input voltage of 4.75 V.

1.07 × 4.75 ÷ 5.00 = 1.02 V

4.61 × 4.75 ÷ 5.00 = 4.38 V

Thus, the valid range is 1.02

Rating of Bulb [A]: 12 V × 3 ∼ 3.4 W

Terminal Width [B]: 1.8 mm (0.07 in.)

Terminal Thickness [C]: 0.8 mm (0.03 in.)

CAUTION

Do not use larger terminals than specified above. A larger terminal could damage the injector main harness connector (female), leading to harness repair or replacement.

Be sure to connect bulbs in series. The bulb works as a current limiter to protect the solenoid in the injector from excessive current.

Remove connectors for injector [A].

Connect each test light set [B] to the injector sub harness connector [C].

Turn the ignition switch ON.

While cranking the engine with the starter motor, watch the test lights.

If the test lights flicker at regular intervals, the injector circuit in the ECU, and the wiring are good. Perform the

“Injector Resistance Inspection”.

Injector signals can be also confirmed by connecting the hand tester (× 10 V AC) instead of the test light set to the injector main harness (female) connector. Crank the engine with the starter motor, and check to see if the hand oscillates at regular intervals.

4-4 COOLING SYSTEM

Coolant Flow Chart

Permanent type antifreeze is used as a coolant to protect the cooling system from rust and corrosion.

When the engine starts, the water pump turns and the coolant circulates.

The thermostat is a wax pellet type which opens or closes with coolant temperature changes. The thermostat continuously changes its valve opening to keep the coolant temperature at the proper level.

When coolant temperature is 55°C (131°F) or more, the thermostat closes so that the coolant flow is restricted through the air bleeder hole, causing the engine to warm up more quickly. When coolant temperature is more than 58 ∼ 62°C (136 ∼ 144°F), the thermostat opens and the coolant flows.

When the coolant temperature goes up beyond 95 ∼ 101°C (203 ∼ 214°F), the radiator fan switch conducts to operate the radiator fan. The radiator fan draws air through the radiator core when there is not sufficient air flow such as at low speeds. This increases up the cooling action of the radiator.

When the coolant temperature goes down from the operation temperature by 3 ∼ 8°C (37 ∼ 46°F), the fan switch opens and the radiator fan stops.

In this way, this system controls the engine temperature within narrow limits where the engine operates most efficiently even if the engine load varies.

The system is pressurized by the radiator cap to suppress boiling and the resultant air bubbles which can cause engine overheating. As the engine warms up, the coolant in the radiator and the water jacket expands. The excess coolant flows through the radiator cap and hose to the reserve tank to be stored there temporarily. Conversely, as the engine cools down, the coolant in the radiator and the water jacket contracts, and the stored coolant flows back to the radiator from the reserve tank.

The radiator cap has two valves. One is a pressure valve which holds the pressure in the system when the engine is running. When the pressure exceeds 0.95

∼ 1.25 kgf/m² (14 ∼ 18 psi), the pressure valve opens and releases the pressure to the reserve tank. As soon as pressure escapes, the valve closes, and keeps the pressure at 0.95

∼ 1.25 kgf/m² (14 ∼ 18 psi). When the engine cools down, another small valve (vacuum valve) in the cap opens. As the coolant cools, the coolant contracts to from a vacuum in the system. The vacuum valve opens and allows the coolant from the reserve tank to enter the radiator.

Coolant Deterioration Inspection

Visually inspect the coolant in the reserve tank.

If whitish cotton-like wafts are observed, aluminum parts in the cooling system are corroded. In either case, flush the cooling system.

If the coolant gives off an abnormal smell, check for a cooling system leak. It may be caused by exhaust gas leaking into the cooling system.

Coolant Level Inspection

NOTE

Check the level when the engine is cold (room or ambient temperature).

Check the coolant level in the reserve tank with the motorcycle held perpendicular. The coolant level should be between the “F” (full) [A] level and the “L” (low) [B] level.

If the coolant level is lower than the low level line, add coolant to the full level line.

CAUTION

For refilling, add the specified mixture of coolant and soft water.

Adding water alone dilutes the coolant and degrades its anticorrosion properties.

The diluted coolant can attack the aluminum engine parts. In an emergency, soft water alone can be added, but the diluted coolant must be returned to the correct mixture ratio within a few days.

If coolant must be added often, or the reservoir tank has run completely dry, there is probably leakage in the cooling system. Check the system for leaks.

Coolant Draining

Refer to the Coolant Change in the Periodic Maintenance chapter.

Coolant Filling

Refer to the Coolant Change in the Periodic Maintenance chapter.

Coolant

Pressure Testing

Remove:

Right Lower Inner Cover (see Frame chapter)

Right Air Inlet Duct (see Fuel System (DFI) chapter)

Remove the radiator cap, and install a cooling system pressure tester [A] on the filler neck.

NOTE

Wet the cap sealing surfaces with water or coolant to prevent pressure leaks.

Build up pressure in the system carefully until the pressure reaches 123 kPa (1.25 kgf/cm², 18 psi).

CAUTION

During pressure testing, do not exceed the pressure for which the system is designed. The maximum pressure is 123 kPa (1.25 kgf/cm², 18 psi).

Watch the gauge for at least 6 seconds.

If the pressure holds steady, the system is all right.

If the pressure drops and no external source is found, check for internal leaks. Droplets in the engine oil indicate internal leakage. Check the cylinder head gasket and the water pump.

Remove the pressure tester, replenish the coolant, and install the radiator cap.

Cooling System Flushing

Over a period of time, the cooling system accumulates rust, scale, and lime in the water jacket and radiator. When this accumulation is suspected or observed, flush the cooling system. If this accumulation is not removed, it will clog up the water passage and considerable reduce the efficiency of the cooling system.

Drain the cooling system (see Coolant Change in the Periodic Maintenance chapter).

Fill the cooling system with fresh water mixed with a flushing compound.

CAUTION

Do not use a flushing compound which is harmful to the aluminum engine and radiator. Carefully follow the instructions supplied by the manufacturer of the cleaning product.

Warm up the engine, and run it at normal operating temperature for about ten minutes.

Stop the engine, and drain the cooling system.

Fill the system with fresh water.

Warm up the engine and drain the system.

Repeat the previous two steps once more.

Fill the system with a permanent type coolant and bleed the air from the system (see Coolant Change in the Periodic Maintenance chapter).

Valves

Seat Cutter Operation Care:

1. This valve seat cutter is developed to grind the valve for repair. Therefore the cutter must not be used for other purposes than seat repair.

2. Do not drop or shock the valve seat cutter, or the diamond particles may fall off.

3. Do not fail to apply engine oil to the valve seat cutter before grinding the seat surface. Also wash off ground particles sticking to the cutter with washing oil.

NOTE

Do not use a wire brush to remove the metal particles from the cutter. It will take off the diamond particles.

4. Setting the valve seat cutter holder in position, operate the cutter in one hand. Do not apply too much force to the diamond portion.

NOTE

Prior to grinding, apply engine oil to the cutter and during the operation, wash off any ground particles sticking to the cutter with washing oil.

5. After use, wash it with washing oil and apply thin layer of engine oil before storing.

Marks Stamped on the Cutter

The marks stamped on the back of the cutter [A] represent the following.

Operating Procedures

Clean the seat area carefully.

Coat the seat with machinist’s dye.

Fit a 45° cutter into the holder and slide it into the valve guide.

Press down lightly on the handle and turn it right or left.

Grind the seating surface only until it is smooth.

CAUTION

Do not grind the seat too much. Overgrinding will reduce valve clearance by sinking the valve into the head. If the valve sinks too far into the head, it will be impossible to adjust the clearance, and the cylinder head must be replaced.

Original Seating Surface [B]

NOTE

Remove all pittings of flaws from 45° ground surface.

After grinding with 45° cutter, apply thin coat of machinist’s dye to seating surface. This makes seating surface distinct and 32° and 60° grinding operation easier.

When the valve guide is replaced, be sure to grind with

45° cutter for centering and good contact.

If the outside diameter [A] of the seating surface is too large, make the 32° grind described below.

If the outside diameter of the seating surface is within the specified range, measure the seat width as described below.

Grind the seat at a 32° angle [B] until the seat O.D. is within the specified range.

To make the 32° grind, fit a 32° cutter into the holder, and slide it into the valve guide.

Turn the holder one turn at a time while pressing down very lightly. Check the seat after each turn.

CAUTION

The 32° cutter removes material very quickly.

Check the seat outside diameter frequently to prevent overgrinding.

After making the 32° grind, return to the seat O.D. measurement step above.

To measure the seat width, use a vernier caliper to measure the width of the 45° angle portion of the seat at several places around the seat.

If the seat width is too narrow, repeat the 45° grind until the seat is slightly too wide, and then return to the seat

O.D. measurement step above.

Valves

If the seat width is too wide, make the 60° or 55° [A] grind described below.

If the seat width is within the specified range, lap the valve to the seat as described below.

Grind the seat at a 60° or 55° angle until the seat width is within the specified range.

To make the 60° or 55° grind, fit 60° or 55° cutter into the holder, and slide it into the valve guide.

Turn the holder, while pressing down lightly.

After making the 60° or 55° grind, return to the seat width measurement step above.

Correct Width [B]

Lap the valve to the seat, once the seat width and O.D.

are within the ranges specified above.

Put a little coarse grinding compound on the face of the valve in a number of places around the valve head.

Spin the valve against the seat until the grinding compound produces a smooth, matched surface on both the seat and the valve.

Repeat the process with a fine grinding compound.

Lapper [A]

Valve Seat [B]

Valve [C]

The seating area should be marked about in the middle of the valve face.

If the seat area is not in the right place on the valve, check to be sure the valve is the correct part. If it is, it may have been refused too much; replace it.

Be sure to remove all grinding compound before assembly.

When the engine is assembled, be sure to adjust the valve clearance (see Valve Clearance Adjustment section of

Engine Oil and Oil Filter

WARNING

Motorcycle operation with insufficient, deteriorated, or contaminated engine oil will cause accelerated wear and may result in engine or transmission seizure, accident, and injury.

Oil Level Inspection

Check that the engine oil level is between the upper [A] and lower [B] levels in the gauge.

Situate the motorcycle so that it is perpendicular to the ground.

NOTE

If the motorcycle has just been used, wait several minutes for all the oil to drain down.

If the oil has just been changed, start the engine and run it for several minutes at idle speed. This fills the oil filter with oil. Stop the engine, then wait several minutes until the oil settles.

CAUTION

Racing the engine before the oil reaches every part can cause engine seizure.

If the engine oil gets extremely low or if the oil pump or oil passages clog up or otherwise do not function properly, the oil pressure warning light will light. If this light stays on when the engine is running above idle speed, stop the engine immediately and find the cause.

If the oil level is too high, remove the excess oil, using a syring or some other suitable device.

If the oil level is too low, add the correct amount of oil through the oil filter opening. Use the same type and make of oil that is already in the engine.

NOTE

If the engine oil type and make are unknown, use any brand of the specified oil to top off the level in preference to running the engine with the oil level low. Then at your earliest convenience, change the oil completely.

Engine Oil Change

Refer to the Engine Oil Change in the Periodic Maintenance chapter.

Oil Filter Replacement

Wheels (Rims)

Axle Inspection

Visually inspect the front and rear axle for damages.

If the axle is damaged or bent, replace it.

Place the axle in V blocks that are 100 mm (3.94 in.) [A] apart, and set a dial gauge [B] on the axle at a point halfway between the blocks. Turn [C] the axle to measure the runout. The difference between the highest and lowest dial readings is the amount of runout.

If axle runout exceeds the service limit, replace the axle.

Axle Runout/100 mm (3.94 in.)

Standard: 0.05 mm (0.002 in.) or less

Service Limit: 0.2 mm (0.008 in.)

Balance Inspection

Remove the wheel.

Support the wheel so that it can be spun freely.

Spin the wheel lightly, and mark [A] the wheel at the top when the wheel stops.

Repeat this procedure several times. If the wheel stops of its own accord in various positions, it is well balanced.

If the wheel always stops in one position, adjust the wheel balance.

Balance Adjustment

If the wheel always stops in one position, provisionally attach a balance weight [A] on the rim at the marking using adhesive tape.

Rotate the wheel 1/4 turn [B], and see whether or not the wheel stops in this position. If it does, the correct balance weight is being used.

If the wheel rotates and the weight goes up, replace the weight with the next heavier size. If the wheel rotates and the weight goes down, replace the weight with the next lighter size. Repeat these steps until the wheel remains at rest after being rotated 1/4 turn.

Rotate the wheel another 1/4 turn and then another 1/4 turn to see if the wheel is correctly balanced.

Repeat the entire procedure as many times as necessary to achieve correct wheel balance.

Permanently install the balance weight.

Tires

Position the tire on the rim so that the valve [A] is at the tire balance mark [B] (the chalk mark made during removal, or the yellow paint mark on a new tire).

Install the tire on the rim using a suitable commercially available tire changer.

Lubricate the tire beads and rim flanges with soap and water solution or rubber lubricant to help seat the tire beads in the sealing surfaces of the rim while inflating the tire.

Center the rim in the tire beads, and inflate the tire with compressed air until the tire beads seat in the sealing surfaces.

WARNING

Be sure to install the valve core whenever inflating the tire, and do not inflate the tire to more than 400 kPa (4.0 kgf/cm², 57 psi). Overinflation can explode the tire with possibility of injury and loss of life.

Check to see that the rim lines [A] on both sides of the tire sidewalls are parallel with the rim flanges.

If the rim flanges and tire sidewall rim lines are not parallel,

• remove the valve core.

Lubricate the rim flanges and tire beads.

Install the valve core and inflate the tire again

After the tire beads seat in the rim flanges, check for air leaks.

Inflate the tire slightly above standard inflation.

Use soap and water solution or submerge the tire, and check for bubbles that would indicate leakage.

Adjust the air pressure to the specified pressure.

Install the air valve cap.

Install the brake disc(s) so that the disc rotation mark aligns with the tire rotation.

Apply a non-permanent locking agent, and tighten the brake disc bolts.

Torque - Brake Disc Bolts: 27 N·m (2.8 kgf·m, 20 ft·lb)

Adjust the wheel balance.

WARNING

Check and balance the wheel when a tire is replaced with a new one.

New tires are slippery and may cause loss of control and injury.

A break-in period of 160 km (100 miles) is necessary to establish normal tire traction. During break-in, avoid sudden and maximum braking and acceleration, and hard cornering.

Tires

Repair

Currently two types of repair for tubeless tires have come into wide use. One type is called a temporary (external) repair which can be carried out without removing the tire from the rim, and the other type is called permanent (internal) repair which requires tire removal. It is generally understood that higher running durability is obtained by permanent (internal) repairs than by temporary (external) ones.

Also, permanent (internal) repairs have the advantage of permitting a thorough examination for secondary damage not visible from external inspection of the tire. For these reasons, Kawasaki does not recommend temporary (external) repair. Only appropriate permanent (internal) repairs are recommended. Repair methods may vary slightly from make to make. Follow the repair methods indicated by the manufacturer of the repair tools and materials so that safe results can be obtained.

Caliper Fluid Seal Damage

ZX1200-B1/B2

The fluid seals [C] around the pistons [A] maintain the proper pad/disc clearance. If the seals are not satisfactory, pad wear will increase, and constant pad drag on the disc will raise brake and brake fluid temperature.

Replace the fluid seals under any of the following conditions; (a) fluid leakage around the pad; (b) brakes overheat (c) there is a large difference in inner and outer pad wear; (d) the seal is stuck to the piston.

If the fluid seal is replace, replace the dust seal [B] as well. Also, replace all seals every other time the pads are changed.

ZX1200-B3

The fluid seals (piston seal) [A] is placed around the piston to maintain clearance between the pad and the disc. If the seal is in a poor condition, it could lead the pad to wear excessively or the brake to drag, which may cause the temperature of the discs or the brake fluid to increase.

Replace the fluid seal if it exhibits any of the conditions listed below.

Brake fluid leakage around the pad.

Brakes overheat.

Considerable difference in inner and outer pad wear.

Seal and piston are stuck together.

If the fluid seal is replaced, replace the dust seals [B] as well. Also, replace all seals every other time the pads are changed.

Do not use any other fluid for cleaning these parts, Gasoline, engine oil, or any other petroleum distillate will cause deterioration of the rubber parts. Oil Spilled on any part will be difficult to wash off completely, and will eventually deteriorate the rubber used in the disc brake.

Apply brake fluid to the removed parts and to the inner wall of the cylinder.

Take care not to scratch the piston or the inner wall of the cylinder.

Apply silicone grease (ex. PBC grease) to the push rod end, the brake lever end (piston contact portion) and the brake lever pivot bolt journal.

Tighten the brake lever pivot bolt and the locknut.

Brake Fluid

Brake Fluid Level Inspection

Refer to the Brake Fluid Level Inspection in the Periodic

Maintenance chapter.

Brake Fluid Change

Refer to the Brake Fluid Change in the Periodic Maintenance chapter.

Bleeding the Brake Line

The brake fluid has a very low compression coefficient so that almost all the movement of the brake lever or pedal is transmitted directly to the caliper for braking action. Air, however, is easily compressed. When air enters the brake lines, brake lever or pedal movement will be partially used in compressing the air. This will make the lever or pedal feel spongy, and there will be a loss in braking power.

WARNING

Be sure to bleed the air from the brake line whenever brake lever or pedal action feels soft or spongy after the brake fluid is changed, or whenever a brake line fitting has been loosened for any reason.

NOTE

The procedure to bleed the front brake line is as follows.

Bleeding the rear brake line is the same as for the front brake.

Remove the reservoir cap, and diaphragm.

Fill the reservoir with fresh brake fluid to the upper level line in the reservoir.

With the reservoir cap off, slowly pump the brake lever several times until no air bubbles can be seen rising up through the fluid from the holes at the bottom of the reservoir.

Bleed the air completely from the master cylinder by this operation.

Remove the rubber cap from the bleed valve on the caliper.

Attach a clear plastic hose to the bleed valve, and run the other end of the hose into a container.

Bleed the brake line and the caliper as follows:

Repeat this operation until no more air can be seen coming out into the plastic hose.

1. Pump the brake lever until it becomes hard, and apply the brake and hold it [A].

2. Quickly open and close [B] the bleed valve while holding the brake applied.

3. Release the brake [C].

Brake Fluid

NOTE

The fluid level must be checked often during the bleeding operation and replenished with fresh brake fluid as necessary. If the fluid in the reservoir runs completely out any time during bleeding, the bleeding operation must be done over again from the beginning since air will have entered the line.

Tap the brake hose lightly from the caliper to the reservoir for more complete bleeding.

Front Brake: Repeat the above steps for the other caliper.

Rear Brake: Repeat the above steps for the other bleed valve.

Remove the clear plastic hose.

Install the reservoir cap.

Tighten the front reservoir cap screws.

Torque - Front Reservoir Cap Screws: 1.5 N·m (0.15 kgf·m,

13 in·lb)

Tighten the bleed valve, and install the rubber cap.

Torque - Bleed Valve: 7.8 N·m (0.80 kgf·m, 69 in·lb)

Check the fluid level.

After bleeding is done, check the brake for good braking power, no brake drag, and no fluid leakage.

BRAKES 12-27

Brake Fluid

WARNING

When working with the disc brake, observe the precautions listed below.

1. Never reuse old brake fluid.

2. Do not use fluid from a container that has been left unsealed or that has been open for a long time.

3. Do not mix two types and brands of fluid for use in the brake. This lowers the brake fluid boiling point and could cause the brake to be ineffective. It may also cause the rubber brake parts to deteriorate.

4. Don’t leave the reservoir cap off for any length of time to avoid moisture contamination of the fluid.

5. Don’t change the fluid in the rain or when a strong wind is blowing.

6. Except for the disc pads and disc, use only disc brake fluid, isopropyl alcohol, or ethyl alcohol for cleaning brake parts. Do not use any other fluid for cleaning these parts. Gasoline, engine oil, or any other petroleum distillate will cause deterioration of the rubber parts. Oil spilled on any part will be difficult to wash off completely and will eventually deteriorate the rubber used in the disc brake.

7. When handing the disc pads or disc, be careful that no disc brake fluid or any oil gets on them. Clean off any fluid or oil that inadvertently gets on the pads or disc with a high-flash point solvent. Do not use one which will leave an oily residue. Replace the pads with new ones if they cannot be cleaned satisfactorily.

8. Brake fluid quickly ruins painted surfaces; any spilled fluid should be completely wiped up immediately.

9. If any of the brake line fittings or the bleed valve is opened at any time, the AIR MUST BE BLED FROM

THE BRAKE LINE.

Brake Hoses

Brake Hose Removal/Installation

CAUTION

Brake fluid quickly ruins painted or plastic surfaces; any spilled fluid should be completely wiped up immediately with wet cloth.

When removing the brake hose, take care not to spill the brake fluid on the painted or plastic parts.

When removing the brake hose, temporarily secure the end of the brake hose to some high place to keep fluid loss to a minimum.

There are washers on each side of the brake hose fitting.

Replace them with new ones when installing.

When installing the hoses, avoid sharp bending, kinking, flattening or twisting, and route the hoses according to

Hose Routing section in General Information chapter.

Tighten the banjo bolts at the hose fittings.

Torque - Brake Hose Banjo Bolts: 25 N·m (2.5 kgf·m, 18 ft·lb)

Bleed the brake line after installing the brake hose (see

Bleeding the Brake Line).

Precautions

There are a number of important precautions that should be followed servicing electrical systems.

Do not reverse the battery cable connections. This will burn out the diodes on the electrical parts.

Always check battery condition before condemning other parts of an electrical system. A fully charged battery is a must for conducting accurate electrical system tests.

The electrical parts should never be struck sharply, as with a hammer, or allowed to fall on a hard surface. Such a shock to the parts can damage them.

To prevent damage to electrical parts, do not disconnect the battery cables or any other electrical connections when the ignition switch is on, or while the engine is running.

Because of the large amount of current, never keep the starter button pushed when the starter motor will not turn over, or the current may burn out the starter motor windings.

Do not use a meter illumination bulb rated for other than voltage or wattage specified in the wiring diagram, as the meter or gauge panel could be warped by excessive heat radiated from the bulb.

Take care not to short the leads that are directly connected to the battery positive (+) terminal to the chassis ground.

Troubles may involve one or in some cases all items.

Never replace a defective part without determining what

CAUSED the failure. If the failure was caused by some other item or items, they must be repaired or replaced, or the new replacement will soon fail again

Make sure all connectors in the circuit are clean and tight, and examine leads for signs of burning, fraying, etc. Poor leads and bad connections will affect electrical system operation.

Measure coil and winding resistance when the part is cold

(at room temperature).

If any wiring is poor, replace the damaged wiring.

Pull each connector [A] apart and inspect it for corrosion, dirt, and damage.

If the connector is corroded or dirty, clean it carefully. If it

• is damaged, replace it.

Check the wiring for continuity.

Use the wiring diagram to find the ends of the lead which is suspected of being a problem.

Connect the hand tester between the ends of the leads.

Special Tool - Hand Tester: 57001-1394

Set the tester to the × 1 Ω range, and read the tester.

If the tester does not read 0 Ω, the lead is defective. Replace the lead or the wiring harness [B] if necessary.

Battery

Electrolyte Filling

Make sure that the model name [A] of the electrolyte container matches the model name [B] of the battery. These names must be the same.

Battery Model Name for ZX1200-B1 ∼ B3: YTX14-BS

CAUTION

Be sure to use the electrolyte container with the same model name as the battery since the electrolyte volume and specific gravity vary with the battery type. This is to prevent overfilling of the electrolyte, shorting the battery life, and deterioration of the battery performance.

Check to see that there is no peeling, tears or holes in the seal sheet on the top of the battery.

Place the battery on a level surface.

Remove the seal sheet [A].

CAUTION

Do not remove the seal sheet sealing the filler ports

[B] until just before use.

NOTE

A battery whose seal sheet has any peeling, tears, or holes, requires a refreshing charge (initial charge).

Take the electrolyte container out of the plastic bag.

Detach the seal cap [A] from the container.

NOTE

Do not discard the seal cap because it is used as the battery plugs later.

Do not peel back or pierce the seals [B] on the container.

Place the electrolyte container upside down aligning the six seals with the six battery filler ports.

Push the container down strongly enough to break the seals. Now the electrolyte should start to flow into the battery.

NOTE

Do not tilt the container as the electrolyte flow may be interrupted.

Battery

Make sure air bubbles [A] are coming up from all six filler ports.

Leave the container this way for 5 minutes or longer.

NOTE

If no air bubbles are coming up from a filler port, tap [B] the bottom of the container two or three times. Never remove the container from the battery.

CAUTION

Fill the electrolyte into the battery until the container is completely emptied.

Be certain that all the electrolyte has flowed out.

Tap the bottom the same way as above if there is any electrolyte left in the container.

Now pull the container gently out of the battery.

Let the battery sit for 20 minutes. During this time, the electrolyte permeates the special separators and the gas generated by chemical reaction is released.

Fit the seal cap [A] tightly into the filler ports until the seal cap is at the same level as the top of the battery.

NOTE

Do not hammer. Press down evenly with both hands.

WARNING

Once you installed the seal cap after filling the battery, never remove it, nor add any water or electrolyte.

Battery

Initial Charge

While a Sealed battery can be used after only filling with electrolyte, a battery may not be able to sufficiently move a starter motor to start an engine in the cases shown in the table below, where an initial charge is required before use. However, if a battery shows a terminal voltage of 12.6 V or more, using a digital volt meter, after 10 minutes of filling, no initial charge is necessary.

NOTE

To measure battery terminal voltage, use a digital voltmeter which can be read one decimal place voltage.

Condition requiring initial charge

At low temperature (lower than 0°C)

Battery has been stored under high temperature and humidity.

Seal sheet has been removed, or broken – peeling, tear or hole.

Battery two or more years old from date of manufacture.

Battery manufacturing date is printed on battery top.

Precautions

1) No need of topping-up

No topping-up is necessary in this battery until it ends its life under normal use. Forcibly prying off the seal cap to add water is very dangerous. Never do that.

2) Refreshing charge

If an engine will not start, a horn sounds weak, or lamps are dim, it indicates the battery has been discharged. Give refresh charge for 5 to 10 hours with charge current shown in the specification

(see this chapter).

When a fast charge is inevitably required, do it following precisely the maximum charge current and time conditions indicated on the battery.

CAUTION

This battery is designed to sustain no unusual deterioration if refresh-charged according to the method specified above. However, the battery’s performance may be reduced noticeably if charged under conditions other than given above. Never remove the seal cap during refresh charge.

If by chance an excessive amount of gas is generated due to overcharging, the relief valve releases the gas to keep the battery normal.

3) When you do not use the motorcycle for months:

Give a refresh charge before you store the motorcycle and store it with the negative cable removed. Give a refresh charge once a month during storage.

4) Battery life:

If the battery will not start the engine even after several refresh charges, the battery has exceeded its useful life. Replace it (Provided, however, the vehicle’s starting system has no problem).

WARNING

Keep the battery away from sparks and open flames during charging, since the battery gives off an explosive gas mixture of hydrogen and oxygen. When using a battery charger, connect the battery to the charger before turning on the charger.

This procedure prevents sparks at the battery terminals which could ignite any battery gases.

No fire should be drawn near the battery, or no terminals should have the tightening loosened.

The electrolyte contains sulfuric acid. Be careful not to have it touch your skin or eyes. If touched, wash it off with liberal amount of water. Get medial attention if severe.

ELECTRICAL SYSTEM 16-19

Battery

Interchange

The sealed battery can fully display its performance only when combined with a proper vehicle electric system. Therefore, replace the sealed battery only on a motorcycle which was originally equipped with the sealed battery.

Be careful, if the sealed battery is installed on a motorcycle which had an ordinary battery as original equipment, the sealed battery’s life will be shortened.

Charging Condition Inspection

Battery charging condition can be checked by measuring

• battery terminal voltage.

Remove the battery (see Battery Removal).

Measure the battery terminal voltage.

NOTE

Measure with a digital voltmeter [A] which can be read one decimal place voltage.

If the reading is below the specified, refreshing charge is required.

Battery Terminal Voltage

Standard: 12.6 V or more

Refreshing Charge

Remove the battery [A] (see Battery Removal).

Install the rotor and tighten it with 70 N·m (7.0 kgf·m, 52 ft·lb) of torque.

Remove the rotor bolt.

Check the drawing torque with the part (bolt) of the flywheel puller.

Special Tool - Flywheel Puller Assembly: 57001-1405

If the rotor is not pulled out with 20 N·m (2.0 kgf·m, 15 ft·lb) of drawing torque, it is installed correctly.

If the rotor is pulled out with under 20 N·m (2.0 kgf·m, 15 ft·lb) of drawing torque, clean off any oil dirt or flaw of the crankshaft and rotor tapered portion, and dry them with a clean cloth. Then, confirm that it is not pulled out with above torque.

Tighten the alternator rotor bolt while holding the alternator rotor steady with the flywheel holder.

Special Tool - Flywheel Holder: 57001-1313

Torque - Alternator Rotor Bolt: 110 N·m (11 kgf·m, 81 ft·lb)

Install the alternator cover (see Alternator Cover Installation).

Alternator Inspection

There are three types of alternator failures: short, open

(lead burned out), or loss in rotor magnetism. A short or open in one of the stator coil leads will result in either a low output, or no output at all. A loss in rotor magnetism, which may be caused by dropping or hitting the alternator, by leaving it near an electromagnetic field, or just by aging, will result in low output.

To check the alternator output voltage, do the following procedures.

Turn off the ignition switch.

Remove the seat cover (see Frame chapter).

Charging System

Disconnect the alternator lead connectors [A].

Connect the hand tester [B] as shown in the table 1.

Special Tool - Hand Tester: 57001-1394

Start the engine.

Run it at the rpm given in the table 1.

Note the voltage readings (total 3 measurements).

If the output voltage shows the value in the table, the alternator operates properly and the regulator/rectifier is damaged. A much lower reading than that given in the table

• indicates that the alternator is defective.

Check the stator coil resistance as follows.

Stop the engine.

Connect the hand tester as shown in the table 2.

Note the readings (total 3 measurement).

If there is more resistance than shown in the table, or no hand tester reading (infinity) for any two leads, the stator has an open lead and must be replaced. Much less than this resistance means the stator is shorted, and must be replaced.

Using the highest resistance range of the hand tester, measure the resistance between each of the Yellow leads and chassis ground.

Any hand tester reading less than infinity (∞) indicates a short, necessitating stator replacement.

If the stator coils have normal resistance, but the voltage check showed the alternator to be defective; then the rotor magnets have probably weakened, and the rotor must be replaced.

The resistance should be low in one direction and more than ten times as much in the other direction. If any two leads are low or high in both directions, the rectifier is defective and must be replaced.

NOTE

The actual meter reading varies with the meter used and the individual rectifier, but, generally speaking the lower reading should be from zero to one half the scale.

Charging System

Regulator Circuit Check

To test the regulator out of circuit, use three 12 V batteries and a test light (12 V 3 ∼ 6 W bulb in a socket with leads).

CAUTION

The test light works as an indicator and also a current limiter to protect the regulator/rectifier from excessive current. Do not use an ammeter instead of a test light.

Check to be sure the rectifier circuit is normal before continuing.

Regulator Circuit Test: 1st Step

Connect the test light and the 12 V battery to the regulator/rectifier as shown.

Check Y1, Y2, and Y3 terminal respectively.

If the test light turns on, the regulator/rectifier is defective.

Replace it.

If the test light does not turn on, continue the test.

ELECTRICAL SYSTEM 16-27

Regulator Circuit Test: 2nd Step

Connect the test light and the 12 V battery in the same manner as specified in the "Regulator Circuit Test–1st

Step".

Apply 12 V to the BR (voltage monitoring) terminal.

Check Y1, Y2, and Y3 terminal respectively.

If the test light turns on, the regulator/rectifier is defective.

Replace it.

If the test light does not turn on, continue the test.

16-28 ELECTRICAL SYSTEM

Charging System

Regulator Circuit Test: 3rd Step

Connect the test light and the 12 V battery in the same manner as specified in the "Regulator Circuit Test–1st

Step".

Momentarily apply 24 V to the BR terminal by adding a 12

V battery.

Check Y1, Y2, and Y3 terminals respectively.

CAUTION

Do not apply more than 24 V to the regulator/rectifier and do not leave the 24 V applied for more than a few seconds, or the unit will be damaged.

If the test light did not light when the 24 V was applied momentarily to the BR terminal, the regulator/rectifier is defective. Replace it.

If the regulator/rectifier passes all of the tests described, it may still be defective. If the charging system still does not work properly after checking all of the components and the battery, test the regulator/rectifier by replacing it with a known good unit.

Regulator/Rectifier Output Voltage Inspection

ZX1200-B1/B2

Check the battery condition (see Battery section).

Remove the seat cover (see Frame chapter).

Warm up the engine to obtain actual alternator operating conditions.

Turn off the ignition switch, and connect the lead wire

-voltage regulator adapter [A] between the regulator/rectifier lead 5 pins connectors [B] as shown in the figure.

Connect the hand tester to the connector [C] of the adapter as shown in the table.

Start the engine, and note the voltage readings at various engine speeds with the headlight turned on and then turned off. (To turn off the headlight of U.S.A., Canadian,

Australian and Malaysian models, disconnect the headlight connector in the upper fairing.) The readings should show nearly battery voltage when the engine speed is low, and as the engine speed rises, the readings should also rise. But they must be kept under the specified voltage.

If the regulator/rectifier output voltage is kept between the values given in the table, the charging system is considered to be working normally.

If the output voltage is much higher than the values specified in the table, the regulator/rectifier is defective or the regulator/rectifier leads are loose or open.

If the battery voltage does not rise as the engine speed increases, then the regulator/rectifier is defective or the alternator output is insufficient for the loads. Check the alternator and regulator/rectifier to determine which part is defective.

16-70 ELECTRICAL SYSTEM

Immobilizer System (Equipped Models) (ZX1200-B3)

This motorcycle is equipped with an immobilizer system to protect the motorcycle from theft. This system provides a theft proof device by means of matching a code between the inbuilt key transponder and ECU (Electronic Control Unit). If the code does not match, ignition system, injectors and sub

-throttle valve actuator will not operate and the engine will not start.

Abstract

Do not keep more than one immobilizer key of any system on a key ring. Jamming of the key code signal may occur and the operation of the system may be affected.

The FI indicator light illuminates for two seconds and then extinguishes when the ignition is first switched on. This shows the system is operating correctly.

If the FI indicator light illuminates when the ignition switch is turned to the ON position and stays illuminated this shows a fault in the DFI system.

If the FI indicator light flashes when the ignition switch is turned to the ON position this shows the immobilizer system has a fault. Refer to service code to identify the faulty component.

The FI indicator light will flash for a period of 24 hours once the ignition switch has been switched off and the key removed. This flashing can be set to on or off as desired by holding the Mode and

Reset buttons down for two seconds within twenty seconds of switching the ignition off.

If all coded keys (master key and user keys) are lost the ECU and ignition switch will have to be replaced.

The immobilizer system can not function until the master key code is registered in the ECU.

A total of six keys can be registered in the ECU at any one time (one master key and five user keys).

If the master key is lost it is not possible to register new user keys.

Operational Cautions

1. Do not put two keys of any immobilizer system on the same key ring.

2. Do not submerge any key in water.

3. Do not expose any key to excessively high temperature.

4. Do not place any key close to magnet.

5. Do not place a heavy item on any key.

6. Do not grind any key or alter its shape.

7. Do not disassemble the plastic part of any key.

8. Do not drop the key and/or apply any shocks to the key.

9. When a user key is lost, the user should go to his dealer to invalidate the lost key registration in the electronic control unit (ECU).

10.When the master key is lost, the user should go to his dealer and have a new ECU installed and register a new master key and user keys.

NOTE

No.9 and 10 are strongly recommended to the customer to ensure security of the motorcycle.
