Few degrees before BTDC, spark plug produces spark. flows out. 02-1 BASIC TERMINOL OGY OF AUT OMOBILES TERMINOLOGY AUTOMOBILES ENGINE : The Engine helps to convert Chemical energy availbale in petrol into heat energy then to mechanical energy for motion. It is the heart of the vehicle in which power is generated for moving the vehicle. Fuel Power Air BORE : Bore is the inside diameter of the cyclinder block in which Piston moves up and down. TDC : TDC stands for Top Dead Center. It is the top most position to which the piston can travel in the cylinder barrel. BDC : BDC stands for Bottom Dead Center. It is the bottom most position to which the piston can travel in the cylinder barrel. STROKE : It is a distance travelled by piston from TDC to BDC or Vice Versa. CUBIC CAPACITY / DISPLACEMENT : It is a volume generated by piston when it travels from TDC to BDC. It is measured as Cubic Centimeter (CC). It can be mathematically arrived at with the radious of the piston and the stroke of the engine. (πr²× l, when ‘r’ is the radius of the piston and ‘l’ is the length of the stroke). It is also known as Swept Volume or Displacement volume. CLEARANCE VOLUME : It is the nominal volume of the space above the piston in the combustion chamber when piston is at the topmost position (TDC). 02-2 TOTAL VOLUME : It is the sum of the swept voume (Displacement volume) and Clearance volume. Total Volume = Swept volume + Clerance volume. COMPRESSION RATIO : It is a ratio between total volume in the engine to the clearance volume available at the end of compression stroke. Compression ratio = Total volume of air fuel mixture Clearance volume VOLUMETRIC EFFICIENCY : Volumetric efficiency is the ratio between the volume of air fuel mixture that actually enters the cylinder and Swept volume. Volumetric Efficiency = Volume of air fuel mixture inhaled during suction stroke Swept volume HORSE POWER (HP OR PS) : HP : Horse Power PS : PFERDESTARKE is German unit of power. Horse Power is the ability of the engine to do a certain amount of work in a given time. One Horse power is the power required for lifting a weight of 75 Kg. through vertical distance of one meter in one second. Conversion : 1PS = 0.986 HP = 0.735 KW 1 HP = 1.014 PS = 0.744 KW 1KW = 1.360 PS = 1.340 HP 02-3 IHP : IHP stands for Indicated Horse Power. Indicated Horse Power is the power actually developed inside the engine cylinder by combustion process. It is utilised to drive the piston. FHP : 1HP (Horse Power Available after explosion) FHP (Frictional Losses) FHP stands for Frictionl Horse Power. It is the amount of horse power used or lost to overcome the friction between various engine components. BHP : BHP stands for Brake Horse Power BHP (Horse Power Avaiable at Crankshaft) Brake Horse Power is the amount of Power actually available at the crankshaft or output shaft. It is calculated by using dynamometer. BHP = IHP - FHP MECHANICAL EFFICIENCY : Mechanical Efficiency is the ratio between Brake horsepower and Indicated horse power. Brake horsepower Indicated Horse power = BHP IHP TORQUE : Torque is a twisting or turning force or effort. It is the product of a distance and force in circular motion. In the picture shown the torque-applied is the product of distance (distance between the center of the bolt and point where force is acting) and the amount of force applied. With the same force, if the distance is increased, the torque will also increase and if distance is reduced, torque applied will also be reduced. CONVERSION : 1kg-m = 7.23 lb.ft = 9.81 N-m. 1lb.ft = 0.138 Kg-m = 1.356 N-m. 1 N-m = 0.102 Kg-m = 0.737 lb.ft 02-4 IGNITION TIMING : Ignition timing is the timing at which spark commences so that the spark from the spark plug can ignite the mixture in the combusion chamber at the end of TDC during compression stroke. TDC Position Ignition Timing Position If spark occurs earlier than specified ignition timing, it is called “Advance” timing. If spark occurs after the specified ignition timing, it is called “Retard” timing. IDLING SPEED : Ignition Timing in Degrees It is the speed of the crankshaft (i.e. RPM) of the engine when the throttle is in closed pisition. GEAR RATIO : The relative rotation between “Driven Gear” and “Driving Gear” is known as the “Gear Ratio”. It is determined by number of teeth on the respective gears. No. of teeth of Driven Gear Gear Ratio = No. of teeth of Driving Gear In Fig. 1, the Gear ratio is 20 ÷ 10 = 2 : 1 In Fig. 2, the Gear ratio is 20 ÷ 20 = 1 : 1 Gear ratios multiply the engine torque to fulfil various demands for pulling the vehicle like. - More effort is required during initial movement of the vehicle. - More effort is required to climb an elevation. - More effort is required while driving in muddy or sandy surfaces. FINAL DRIVE RATIO : It is a relative rotation between the engine sprocket and the sprocket on the rear wheel. Both the sprockets are connected through drive chain. Final drive ratio further multiplies the torque available at the output shaft. 02-5 TECHNICAL SPECIFICA TIONS SPECIFICATIONS A.

DECARBONISING (EVERY 30,000 KMS) CYLINDER HEAD ( For further details please Ref. page No.09-3) Remove carbon from the valves, ports and combustion chamber by scrapping. Take care not to cause any damage to the valve faces or valve seat inserts. Scrape gently to avoid scoring the cylinder head. 03-20 Remove the piston rings carefully. For cleaning the groove in the piston, a piece of broken piston ring thrust into a wooden handle and filed to a chisel point can be used. Standard Service Limit : 0.9 - 1.1 mm : 1.5 mm Valve seat width is not within specification, reface the valve seat. CYLINDER HEAD AND VALVES CAUTION : VALVE SEAT INSPECTION If a valve face is burnt or badly worn or if it contacts the seat unevenly, replace the valve. Clean both Inlet & Exhaust valves and thoroughly remove the carbon deposits Inspect the valve seat face for : Damage face : Replace the valve and reface the valve seat. Uneven seat width : Bent or collapsed valve stem. Replace the valve and reface the valve seat. Apply light coating of Prussian blue to the valve seats. NOTE : Ensure proper valve seat contact by taping the valve in the valve seat without rotating. Remove the valve and inspect the width of each seat. The seat contact should be within the specified width and even all around the circumference Contact area is too high or too low. Reface the valve seat. 03-21 VALVE SEAT REFACING Valve Seat cutters, a grinder or equivalent valve seat refacing equipment are recommended to correct worn valve seat. If the contact area is too high on the valve, the seat must be lowered using a 32 degree flat cutter. If the contact area is too low on the valve, the seat must be raised using a 60 degree inner cutter. NOTE : Use a 45 degree cutter to remove the roughness or irregularities from the seat. Using 32 degree cutter, remove top 1/4 of the existing valve seat material. Using 60 degree cutter, remove the bottom 1/4 of the old seat. Remove the cutter and inspect the area. Install a 45 degree finish cutter and cut the seat to proper width. Reface the valve seat with a 45 degree cutter when a valve guide is replaced. Make sure that all printing and irregularities are removed. Refinish if necessary. Standard seat width : 0.9 - 1.1 mm 03-22 After cutting the seat, apply lapping compound to the valve face and lap the valve using light pressure. NOTE : Excessive lapping pressure may deform or damage the seat. Change the angle of lapping tool frequently to prevent uneven seat wear. Lapping compound can cause damage if it enters between the valve stem and guide. After lapping, wash any residual compound off the cylinder head and valve. NOTE : To avoid damage to the seating face, turn the valve slowly while inserting. Recheck the seat contact after lapping. Clean the cylinder head assembly with solvent and blow through all oil passages with compressed air. Install the valve spring seats and new valve stem seals.

STEP-B In case compression pressure is less than 80 PSI, then refit spark plug & start again to warmup the engine. If compression pressure reading increases, then check for - Improper alignment of piston ring (end gap position) - piston ring jamed in groove. - scoring / seizure of cylinder barrel / piston - worn out piston/rings - worn out cylinder barrel NOTE : In case compression pressure is more than 110 PSI then engine requires Decarbonisation of cylinder head / piston (combustion chamber). 03-24 SECTION FOUR 04 ENGINE LUBRICA TION SY STEM LUBRICATION SYSTEM 04-1 LUBRICA TION SY STEM LUBRICATION SYSTEM ROCKER PUSH ROD FLY HYDRAULIC OIL PUMP CAM STRAINER CRANK OIL SUMP LUBRICATION SYSTEM : Oil from the oil tank is circulated to various parts through a powerful oil pump, the capacity of which is 4.5 litres per minute @ 2750 rpm. The oil in the sump gets filtered through an oill strainer located in the crankcase and then pumped into the oil filter element located in the RH Cover. From here oil is circulated to 3 main areas. The first branch goes to flywheel to lubricate crank shaft as well as barrel piston assembly. The second branch goes to hydraulic tappet to maintain the oil pressure constantly. The third branch goes to rocker assembly and drains down to RH cover chamber through the push rod tunnel. LUBRICATION OIL : 3 Specification: MOTUL 3000 4T PLUS 15W50 API, JASO MA SL - GRADE ESTER-Semi Synthetic 3 Oil capacity: 2.75 l - Initial oil filling: through Oil filler Cap = 2.5 l, through Crankcse LH Cover: 0.25 l Oil pump : TROCHOID TYPE Trichoidal high flow oil pump delivers oil with a pressure of 4.5 Bar. This provides good lubrication to all the moving parts and enhances the life of the moving parts in the engine. 04-2 HYDRA ULIC TAPPETS (ROLLER HYDRA ULIC VAL VE HYDRAULIC HYDRAULIC ALVE LIFTER (RHVL) HYDRAULIC TAPPET : The Hydraulic tappet, (also known as RHVL Roller Hydraulic Valve Lifter) is located between the cam and pushrod in the valve train mechanism. It not only serves as a valve lifter most importantly, it automatically and constantly adjusts itself to compensate for any extra clearance in the valve train mechanism when the engine is running at various RPM. The automatic adjustment is achieved with the aid of hydraulic pressure inside the hydraulic tappet. BENEFITS OF HYDRAULIC TAPPET : 3 Eliminates the need for manual and periodic push rod height adjustments. 3 Compensates for clearances in the valve train mechanism due to wear of moving parts OR due to variations in engine temperature. ROLLER HYDRAULIC VALVE LIFTER OUTER BODY PUSH ROD OIL ESCAPING OIL OIL TRANSFER ANULUS PLUNGER (D) PUSHROD SEAT (C)DISC VALVE (B) OVER HEAD OIL FLOW PATH OIL INLET (E) LOW PRESSURE CHAMBER CHECK BALL SEAT AIR ESCAPE PATH THROUGH PLUNGER CLEARANCE (F) TRAPPED AIR VOLUME (H) HIGH PRESURE CHAMBER OIL HEAD, OIL DELIVERY CONTROL VALVE, LOCKING ACTION CHECK BALL (A) HIGH PRESSURE CHAMBER OIL FLOW PATH ROLLER 04-3 WORKING PRINCIPLE : Oil enters the hydraulic tappets through a feed hole in the body and flows into the plunger through the plunger feed hole, filling the “low pressure chamber” (E, in Figure) The oil also flows around the check ball and through the slots of the ball retainer to fill the cavity below the plunger, called the “high pressure chamber” (A, in Figure). Oil is forced down into this area by momentary low pressure which occurs once during each cam rotation. As the hydrauilic tappet rises due to the cam rotation, the full load of the valve train is applied on the tappet. A predetermined and closely held clearance of .0002/.0003 inch (.0051/.0076 mm) between the outer diameter of the plunger and the inner diameter of the tappet body allows a controlled amount of oil to escape up from the high pressure chamber. This oil compresses the plunger spring and allows a small relative movement of the plunger with respect to the body. The metering valve moves sufficiently to keep the push rod seat hole free and unclogged. When the engine is switched off, the valve seats on the shoulder of the plunger to minimize drain back of oil. If the engine structure or valve train expands or contracts with changes in engine temperature or other differentials, the hydraulic tappets will automatically adjust its own internal length to compensate for these changes. PRECAUTIONARY MEASURES : The hydraulic tappets have minute holes for the oil to circulate and to also act at the hydraulic media, hence oil contamination must be at the minumum. The oil and the filters in the engine, must be changed periodically as specified. Whenever the tappets are removed for service OR stored in spares, they must be kept upright (the push rod seating surface pointing upwards and the rollers at the bottom pointing downwards) to prevent the oil from draining off. As cam further rotates, the tappets returns to its original position. At this time, the plunger spring provides the force to maintain zero back lash in the valve train mechanism and forces the plunger back to its original position. This allows engine oil to once again fill the high pressure chamber so that the cycle can be repeated during the next cam rotation. The overhead oil supply is accurately metered from the “low pressure chamber”, which is at engine oil pressure, by using a flat metal disk (metering valve C, in Figure), which wobbles against a cylindrical radius curved surface on the bottom of the push rod seat (D, in Figure). Oil flows up through the hole in the push rod seat to lubricate the overhead valve train components (oil flow path B, in Figure). 04-4 AUT O DECOMPRESSOR AUTO WORKING PRINCIPLE BENEFITS OF AUTO DECOMPRESSOR : The auto decompressor is assembled in the exhaust cam and consists of a flyweight, spring and pin. These are assembled in the cam assembly with a screw 3 Eliminates the need to fix a manual system which will need to be adjusted and serivced periodically. 3 Helps in easy starting of the engine 3 Helps to reduce high initial load on the electric start motor During inital cranking of the engine, the cam rotation will be under 350 RPM. At this speed, the flyweight will be at its resting position which causes the pin to protrude above the base circle of the cam lobe. This will cause the hydraulic tappet to raise and will cause the exhaust valve to be open thus letting out the compression form the cylinder head. As the engine starts, the cam rotation increases beyond 350 RPM which inturn will cause the flyweight to open and force the pin to rotate and its projection will go below the cam lobe. This will cause the tappet to return to its resting poisition and will close the exhaust valve thus holding the compression required to start the engine 04-5 ELECTRIC ST AR TER SY STEM & SPRA G MECHANISM STAR ARTER SYSTEM SPRAG WORKING PRINCIPLE The sprag is located in the primary sprocket on the crankcase drive side. This provides better rigidity of the sprag mechanism during initial crankin. The auto decompressor mechanism further helps in reducing the load on the sprag during intitial cranking and also prevents reversal phenomenon of the crank shaft. 04-6 AUT O CHAIN TENSIONER ASSEMBL Y UTO ASSEMBLY WORKING PRINCIPLE The auto chain tensioner has a spring loaded plunger mechanism with a ratchet arrangement. It eliminates need for manual adjustment of the primary chain tension. It is assembled on the crankcase LH below the chain tensioner pad. The spring loaded plunger applies force on the chain tensioner pad thereby lifting it and holding aginst the primary chain to the required tension. The oneway rachet mechanism in the auto chain tensioner ensures that the plunger does not drop down due to the downward force of the chain tensioner pad. It does not require any maintenance or service. 04-7 ENGINE BREA THER SY STEM BREATHER SYSTEM Breather arrangement inside the RH cover WORKING PRINCIPLE The engine breather system is located on the RH cover of the crankcase. A connecting hole directs the engine breathing into a chamber in the RH cover which has an inbuilt deflector to deflect the oil that may come along with the fumes from the crankcase. This oil gets drained through a small hole provided at the bottom of the breather chamber. The emission passes through the deflector chamber and goes to the air filter housing and passes through the inlet manifold back into the cylinder head. 04-8 CL UT CH SY STEM CLUT UTCH SYSTEM The clutch system has a seven plate construction to achieve increase effective diameter and improved torque carrying capacity. The clutch is operated through a lever on the cover LH. 04-9 INLET MANIFOLD & THR OTTLE BOD Y THRO BODY The inlet manifold has the fuel injector located on top portion and the throttle body attach to it. The throttle body has a butterfly valve attached which is operated buy the throttle cables attached to a drum on the right side. A manual Bi starter is located on the left side and is the spring and plunger type arrangement. An idle air bypass screw is provided on the throttle body. It is the large brass coloured screw that is accessed from the top of the throttle body. The clamps on the throttle body may be loosened and the throttle body rotated outwards from the top to access the screw without removing the fuel tank and to adjust the idle speed with the bike running. Turn the screw CLOCKWISE (in) to DECREASE the idle speed. Turn the screw ANTICLOCKWISE (out) to increase the idle speed. Remember that this is an AIR BYPASS screw – not a throttle stop screw. Turning the screw about ¼ turn will result in an approximate 200 RPM change in the idle speed. DO NOT adjust the throttle stop screw on the side of the throttle body unless you are using the factory software to recalibrate the base throttle opening. 04-10 Blow Up Charts 04-11 27 31 30,31,32,33,34 Key Nos.

It consists of an Electronic Control Unit (ECU) which constantly takes inputs like engine speed, engine temperature, throttle position, manifold air pressure, exhaust oxygen feed back etc, from the respective sensors, provided in the vehicle and determines both the ignition timing and the ideal amount of fuel to be injected, to optimize the air-fuel ratio. The benefits of EMS are : 3 Excellent cold starting ability. 3 Better fuel economy. 3 Low exhaust emission. 3 Good acceleration. 3 Sustained high speed cruising and driveability. ENGINE MANAGEMENT SYSTEM - FUNCTIONAL DIAGRAM 06-1 COMPONENTS DESCRIPTION ELECTRONIC CONTROL UNIT (ECU) ALTERNATOR THROTTLE BODY ASSEMBLY TEMPERATURE SENSOR FUEL INJECTOR ASSEMBLY CRANK POSITION SENSOR FUEL PUMP MODULE ROLLOVER SENSOR LAMBDA (O2) SENSOR MALFUNCTION INDICATOR LAMP (MIL) 06-2 FUNCTIONS OF COMPONENTS ELECTRONIC CONTROL UNIT (ECU) Located under dual seat (Bullet Electra EFI - E5 / G5) Located in LH Electrical Box (Bullet Classic EFI - C5) The ECU consists of a microprocessor. It controls the output devices by giving pulses to the respective devices. It has two memories Flash Memory and E2 PROM. Flash memory is an exclusive recording unit for controlling program and setting data. It collects different inputs from various sensors and calculates optimised values and gives outputs to the respective controlling devices. E2PROM is an abbreviation for Electronically Erasable Programmable Read Only Memory. This is an exclusive recording unit for breakdown information/history preservation. The main advantage is, the system is nonvolatile and stores the data even when the electricity is off. While in operation the other breakdown information gets recorded automatically. ECU PIN CONFIGURATION Specification Operating Voltage : 8 – 16 V. Sensor Supply Voltage : 5 V. Operating temperature : –10º C to + 60º C. Storage Temperature : –20º C to + 80º C. ECU INTERNAL DIAGRAM 06-3 FUNCTIONS OF COMPONENTS FUEL INJECTOR Exploded view of fuel injector Assembled between throttle body and cylinder head Specification: Operating Voltage : 10 – 14 V. Operating temperature : –30º C to + 120º C. Fuel Injection pressure : 294 kpa (2.9 bar) Solenoid Operating Resistance : 10.3 ± 0.5 Ohms Fuel Injector is a solenoid operated electromagnetic valve, which atomizes the fuel by forcing it through a small nozzle under high pressure. The injection system used is a timed injection system and the injection is done close to the inlet valve. The injector operates based on the pulse width signal given by the ECU. The fuel injector is assembled in the inlet manifold located between the inlet port on the cylinder head and air filter. It is placed at an angle in the intake manifold so as to give maximum fuel spray and minimum wall wetting. The advantages of fuel injection are : 3 Excellent cold starting 3 Consistent idling RPM 3 Good acceleration 3 Full power output 06-4 FUNCTIONS OF COMPONENTS FUEL PUMP MODULE Specification: Operating Voltage : 6 – 14.5 V. Operating temperature : –20º C to + 60º C. Controlled Pressure Regulator : 294 KPa. Inbuilt Filter Capability : Upto 10 Microns Assembled on the fuel tank bottom left side The fuel pump creates a positive pressure in the fuel lines and pumps gasoline through the injector. The Pump operation is determined by the ECU so that it gives exactly the required volume of fuel. The Pump maintains a uniform (294kPa) fuel pressure. Any excess pressure is bypased back into the fuel tank so that the fuel hose, injector etc.do not get damaged due to excess pressure. The fuel pump module has an inbuilt micro fuel filter which filters even the most minute dust particles to prevent damage to the seat in the injector. The pump is located inside the fuel tank so that it is submerged in liquid and hence cannot ignite itself due to electrical sparks and cause an explosion. LOW FUEL SENSOR Specification: Operating voltage : 9V to 16V DC. Fuel level in tank to switch ON : 2.5 ± 0.5 Litres. Lamp load : 12V, 4W Max. Tightening torque : 12 – 14 N-m Operating temperature : – 10°C to +85°C. Assembled in fuel tank bottom RH side A low fuel sensor is provided so that an indication appears in the MIL if the fuel in the tank is less than three litres (0.7 US Gallon). MALFUNCTION INDICATOR LAMP (MIL) Specification: Operating Voltage : 12 V. Bulb Rating : 12V, 4W. Assembled on the headlamp casing Malfunction or abnormalities in any of the EFI components (sensors) is indicated by MIL located on the right side on the headlamp casing. When the ignition key is switched on, the stop switch is in RUN position & the side stand is retracted, the MIL will glow for few seconds, which indicates that the ECU is checking the vital functionality of the sensors. In case of any fault, in the system the MIL will remain “ON” continuously. 06-5 FUNCTIONS OF COMPONENTS THROTTLE BODY MODULE Specification: Operating Voltage : 5 V. Out Put Voltage : 0 – 5V. Throttle Angle : 0 – 80º Throttle Resistance Maximum : 5 K©. Throttle Out Put Voltage at Idling : 0.6 ± 0.2V. Assembled between air filter and inlet manifold Storage Temperature : –20º C to + 80º C The throttle body is a part of the air induction system. It controls the amount of air flowing into the engine, in response to throttle opening. A throttle plate (butterfly valve is use for regulating the airflow) The throttle body also has a throttle position sensor (TPS), a manifold pressure sensor (MAP) and a manual Bi Starter. 06-6 Throttle Position Sensor (TPS): TPS is used to monitor the position of the throttle and is located on the butterfly spindle so that it can directly monitor the position of the butterfly throttle valve. The sensor is usually a potentiometer and therefore provides a variable resistance depending upon the position of the butterfly valve and hence throttle position can be sensed by the ECU. The sensor signal is used by the ECU as an input to its control system. The ignition timing and fuel injection timing (and potentially other parameters) are altered depending upon the position of the throttle, and also depending on the rate of change of the position. The ECU uses the throttle valve position to know: 3 The mode in which the engine is operating. i.e. idle, part throttle, wide-open throttle etc. 3 Emission controls at wide-open Throttle (WOT). 3 Air-fuel ratio correction. 3 Power increase correction. 3 Fuel cutoff control. Manifold Pressure Sensor (MAP): The MAP provides instantaneous manifold pressure information to the ECU. This is necessary to calculate air density and determine the engine’s air mass flow rate, which in turn is used to calculate the appropriate fuel flow to the engine through the injector. Manual BI Starter Located in the throttle body and operated manually through a lever on the handle bar LH. When the lever is pulled down, a cable pulls up the spring loaded piston in the throttle body. Helps in providing additional air into the engine during cold start, for better idling RPM, till the engine operating temperature is attained. 06-7 FUNCTIONS OF COMPONENTS ENGINE TEMPERATURE SENSOR Specification: Operating temperature : –30º C to +120º C Operating Voltage : 5 ± 0.5 V. Resistance Value w.r.t. Temperature –20º C –– 18.8 Kilo Ohms + 40º C –– 1.136 Kilo Ohms + 100º C –– 0.1553 Kilo Ohms Assembled on the cylinder head Engine temperature sensor is used to measure the engine oil temperature. It senses the oil temperature and provides the input to the ECU which calculates the average engine temperature. The ECU accordingly operates the injector to optimise the air fuel ratio. The engine temperature sensor is located in the cylinder head underneath the inlet manifold and on the oil passage. CRANK POSITION SENSOR Specification: Output voltage : 3-5 V AC. Resisitance : 200 ± 20 Ohms Assembled on the engine RH cover The crank position sensor is an inductive pulse generator; the crank sensor scans 23 short and 1 long protrusion on the alternator. The long protrusion is located at 5º before top dead center and is used by the powertrain control module as a reference mark for the crankshaft position. The crank position sensor sends an alternating voltage signal to the powertrain control module, which is used to determine engine speed and ignition timing. Thus the speed of the engine at that instant is known by the ECU. If the engine runs beyond the maximum rated speed (5500 rpm), the ECU cuts off the fuel supply to the injector so that the engine will stall and the RPM will reduce to its rated operating RPM. This is a safety aspect inbuilt to prevent damage to moving engine parts. 06-8 FUNCTIONS OF COMPONENTS LAMBDA (HEGO O2) SENSOR Specification: Operating Voltage : Upto16 V (Maximum). Operating temperature : 600º C to 950º C. (TIP) Tightening Torque : 24.5 ± 4.9 N-m (2.5 ± 0.5 Kg f-m) Assembled on the exhaust pipe The Lambda Sensor detects the presence of oxygen in the exhaust and produces a variable voltage according to the amount of oxygen detected. The sensor provides feedback to the ECU which in turn will meter the air/fuel ratio in order to achieve a near stoichiometric air/fuel ratio of 14.7 : 1 during closed loop engine operation. (The ideal mixture is the amount of fuel needed to make an engine perform as commanded by the ECU). The Lambda sensor is located on the LH side of the exhaust pipe near the cylinder head. The Lambda sensor is temperature sensitive and hence takes approximately 90 seconds to get activated whenever the engine is started. Till the time the Lambda sensor is activated the ECU gives a preset air fuel mixture. ROLL OVER SENSOR Specification: Operating Voltage : 12V. Operating Angle : 60° + 10°. Operating Temperature : –20°C to +85°C. Assembled under the seat The Roll over sensor is also known as a bank angle sensor. If the motorcycle is banking below 60° from the road surface OR in the event of an imminent falling over in a mishap, this sensor signals the ECU which in turn will cut off the fuel supply to the injector and the ignition, thus stalling the engine to prevent further damage that may be caused if the engine is still running with the throttle stuck wide open and the gears are engaged. The Rollover Sensor is located under the seat on the vehicle-mounting strip of the frame (beside ECU). 06-9 There are three levels of identifying a malfunction in the ECU or the sensors. Level 1 Visual This is indicated by the lamp in the MIL glowing continuously. Check for any sensor loose connections and plug in properly. If still MIL GLOWS, then check for the the problem by Test Pin or by DOL TOOL. Level 2 Test pin An open single pole connector is provided close to the UCE.

Do not use any petroleum based cleaning solvents, water or detergents etc. 3 Cover motorcycle painted surfaces, plastic and rubber parts while bleeding a brake system. Do not allow brake fluid to come in contact with any parts of the motorcycle as brake fluid has highly corrosive properties. 3 Always replace brake pads as a set only. 3 Always replace banjo union washers, ‘O’ rings, diaphragm washers, dust seals and piston seals whenever the hydraulic disc brake system is overhauled. 3 Always replace damaged parts like pistons, fixing pin etc. Do not attempt to repair as it may render the disc brake to become ineffective. DISC BRAKE DRAINING OLD BRAKE FL UID FLUID GENERAL INSTRUCTIONS 3 3 Check the system for any fluid leaks at banjo union joints, damaged brake hose etc. 3 Ensure the handle bar is positioned straight and the master cylinder in the handle bar is parallel to the ground, whenever checking fluid level. 3 Clean master cylinder filler cap before removing. 3 Use only DOT 3 or DOT 4 grade brake fluid from a sealed container. Do not mix different types of brake fluid as they may not be compatible. Remove the Master Cylinder top cover screws. 07-4 3 3 Remove the Master Cylinder top cover, diaphragm plate & diaphragm. 3 Loosen the bleeder screw by 1 turn approximately 3 Depress brake lever slowly and fully and release. This will force the brake fluid out of the bleeder screw. Repeat this process till the brake fluid drains out completely from the master cylinder and the wheel calliper assembly. Remove the protective boot from the bleeder nipple on the calliper assembly. OVERHA ULING CALIPER VERHAULING AND MASTER CYLINDER 3 3 Place a clean tray or container below the calliper assembly to collect the old oil. 3 Loosen and remove the banjo bolt with the washers from the Caliper assembly. 3 Drain out the entire brake fluid from the master cylinder and brake hose by depressing and releasing the brake lever. Fix a transparent flexible tube of length 12" (30 Cms.) firmly on the bleeder nipple and insert the other end into a glass or plastic container to collect the old brake fluid. 07-5 3 3 Remove the calliper assembly from the fork leg and drain out the brake fluid 3 Fix the diaphragm, plate and top cover. Do not tighten the screws completely since it may be required to top up fluid during the bleeding process. 3 Depress the brake lever completely and release fully so as to allow the brake fluid to fill up in the brake hose and caliper. 3 When a slight firmness is felt on the lever and it depresses only halfway, hold the lever firmly in that position. DO NOT RELEASE THE LEVER. Reassemble the calliper and refit the banjo bolts after draining out the oil BLEEDING PROCEDURE NORMAL METHOD 3 Ensure the bleeding screw and the brake hose banjo is fully tight. 3 Fix a transparent flexible tube of length 12" (30 Cms.) firmly on the bleeder nipple and insert the other end into a glass or plastic container containing fresh brake fluid. Ensure the tube end is fully immersed in the fluid. This will prevent atmospheric air from getting sucked into the caliper unit during the bleeding process. 3 Fill the master cylinder with brake fluid from a sealed container, till the “MAX” level. 07-6 3 Loosen the bleeder screw by ½ turn to allow air bubbles in the brake system to escape out. 3 Check the fluid level and top up to “MAX” level and refit the diaphragm and the top cover and tighten with the screws. 3 Check for any leaks at the banjo or the bleeding screw area and ensure all mounting bolts are tightened to the correct torque. BLEEDING PROCEEDURE REVERSE BLEEDING METHOD: 3 When the bleeder screw is loosened and the air escapes out along with the brake fluid through the bleeder nipple, the brake lever will further depress. Allow the lever to depress fully and hold. DO NOT RELEASE THE LEVER. 3 Tighten the bleeder screw firmly and then only release the brake lever. 3 Ensure the bleeding screw and the brake hose banjo is fully tight. 3 Fill the master cylinder with brake fluid from a sealed container, till the “Max” level. 3 Depress the brake lever completely and release fully so as to allow the fluid to travel into the brake hose and the wheel caliper. NOTE: Check the fluid level in the master cylinder and top up if necessary till the “MAX” mark. 3 Repeat the process detailed above, till the brake lever movement is minimal and locks in applied position. Also check and ensure there are no more air bubbles being carried out by the fluid while bleeding the system. 3 Ensure the bleeder screw is tightened fully and fix the dust cap. 07-7 3 When a slight pressure “build up” is felt on the lever, depress and hold. DO NOT RELEASE THE LEVER. The air in the hydraulic system will be expelled upwards during this operation, allowing the fluid to fill up in the calliper and the brake hose completely. 3 Remove the Master Cylinder top cover, diaphragm plate & diaphragm. 3 Place a clean tray or container below the calliper assembly to collect the old brake fluid. 3 Loosen and remove the banjo bolt with the washers from the Caliper assembly. 3 Drain out the entire brake fluid from the master cylinder and brake hose by depressing and releasing the brake lever. 3 Remove the calliper assembly from the fork leg and drain out the brake fluid NOTE: The brake fluid level will go down when the air escapes out. Check level constantly and top up to “MAX” level. 3 Repeat the process detailed above, till the brake lever movement is minimal and locks in applied position.

REMOVAL AND ASSEMBLY OF REAR SHOCK ABSORBER Remove the top and bottom mounting nuts and washers. GAS FILLED SHOCK ABSORBER WORKING PRINCIPLE The pressure of the nitrogen/Air, in the reserve tube of a gas charged shock varies from 75 to 120 psi, depending on the amount of fluid in the reserve tube. The gas serves several important functions to improve the ride control characteristics of the shock absorbers. Pull out the shock absorber from bottom and slide out from frame. Assemble in the reverse of removal. ADJUSTMENT OF SHOCK ABSORBERS Adjust the Shock absorber using the special tool No. ST 25244-4 as shown in Fig. (This adjustment may be done as per customer / road condition requirement). The main function is to increase the resistance of fluid flow into the reserve tube. This improves valving performance during the beginning of rebound stroke. Another function is to minimize aeration of the shock absorber’s hydraulic fluid. The pressure of the nitrogen gas / air prevents air bubbles or foam from weakening the hydraulic effectiveness of fluid flow through both the piston and base valve systems. Foam affects performance since foam compresses, fluid does not. This is alternatively called as cavitation. The effect of foaming will result in poor riding comfort. NOTE : Ensure both side adjustment notch are in same position. 08-7 RECHARGING OF SHOCK ABSORBERS Remove the small screw with “O” Ring. Remove the rear wheel sprocket assembly (1). Remove the shock absorbers (2). 2 1 Remove the chain guard.

SCR 09-1 PRECA UTIONS : PRECAUTIONS 3 Wear rubber gloves while handling a battery. 3 Use only constant current battery charger of correct charging rate, to charge batteries. 3 Remove the filler caps only to fill distilled water OR if the battery is to be charged. Hydration may occur when atmospheric air contacts the plates. 3 Keep all the filler caps removed while charging the battery. 3 Use only distilled water to top up the level after the initial charging. 3 During charging, the electrolyte temperature should not exceed 45ºC if necessary, discontinue the charging to cool the electrolyte. 3 Ensure that the battery is placed on a nonmetallic surface while charging. 3 Keep fire and spark away from battery charging area. 3 Never run the motorcycle without connecting the battery as it may lead premature failure of electrical parts. CAUTION : It is important to ensure that the sulphuric acid is added into the distilled water and not vice versa. Stir and check the specific gravity of electrolyte and add sulphuric acid till the specific gravity becomes 1.240 Never add sulphuric acid to battery electrolyte for topping up or increasing specific gravity. It would lead to sulphation. 3 Stir with a glass rod. 3 Check the specific gravity with hydrometer. CHARGING INITIAL CHARGE (NEW BATTERY) ELECTROLYTE : 3 Diluted sulphuric acid with distilled water to a specific gravity of 1.240 PREPARATION : 3 Take required distilled water in a Hydrometer or equivalent container. 3 Slowly, add sulphuric acid to it. 09-2 TEMPERATURE OF ELECTROLYTE : 3 CAUTION : Cool the electrolyte to about 30 deg. C before filling it in the battery, just below the maximum level indicated. Always connect the positive and negative terminals of battery into the positive and negative sockets provided in the constant current battery charger. SOAKING PERIOD: 3 Always disconnect the Negative (-ve) terminal first & then the Positive (+ve). When re-connecting the battery to the vehicle after re-charging first connect Positive(+ve) terminal & then the Negative(ve) terminal. Keep the battery with electrolyte filled for about half an hour before commencement of charging. Top up the level with electrolyte if necessary. C HAR GING A NEW B ATTER Y: HARGING BA TTERY 3 Connect the battery to the charger and charge as detailed below.. Battery Duration Charging Current 12V 14AH 10Hrs 1.4 Amps RECHARGING USED B ATTERIES TTERIES:: 3 3 When the specific gravity of electrolyte is less than 1.220, drain out the electrolyte and refill with fresh electrolyte of strength 1.240 and charge the battery as detailed above. when a charged battery remains unused for more than 3 weeks, check the electrolyte for correct specific gravity, top up if required with distilled water up to maximum mark and charge the battery. Keep all battery filler caps open while charging. CHARGING procedure: 3 Switch on the mains ‘ON’. See that the charger indicator light is glowing 3 Switch on the charger ON/OFF switch 3 Disconnect the battery from the charger when fully charged. INDICATION OF FULL CHARGE: 3 Free gassing from electrolyte for more than 90 minutes. 3 3 consecutive reading taken in intervals of 30 minutes each to read constantly 1 .240 or more of specific gravity. 3 Voltage: 12.0 TO 13.2V 09-3 MAINTENANCE 3 Check the electrolyte level and top up, if necessary to the ‘MAX’ mark with distilled water every week. 3 Protect battery from direct sunlight, heat, rain and dust. 3 Keep exhaust seal cap in place to avoid deterioration of dry charge properties 3 New dry charged batteries need initial charging duration of 8 to 10 hours - Upto 3 months from the date of manufacturing. 3 Beyond 3 months the batteries may need extended duration of initial charging subject to storage conditions. 3 Charged batteries, if kept idle should be boost charged once in 3 to 4 weeks 3 It is always a good practice to boost charge the batteries before fitment to ensure full state of charge. 3 Check the terminals and cables for corrosion. Apply petroleum jelly on terminals to prevent corrosion. 3 Check specific gravity of electrolyte. The float graduation in level with the electrolyte in it, is the specific gravity of the electrolyte. CAUTION : For topping, use only distilled water. 3 Keep the battery surface clean and dry. 3 Never over charge the battery - it damages the battery & plates may buckle. 3 Remove the battery from the motorcycle and store it separately when the motorcycle is not in operation for more than one month. 09-4 Specific Gravity Fully charged Carbon deposits on the spark plug establishes a ‘shunt’ between center and earth electrodes, that prevents good sparking and causes misfiring. Clean the deposits off periodically, with a spark plug cleaning tool / machine. 3 Check spark plug for pitted out the earth and center electrodes. If the earth electrode has worn off to a knife edge and center electrode has reduced in height, replace it with new.
