Fuel and Oil Recommendations
Fuel and Oil Recommendations
Fuel
Use unleaded gasoline with an octane number 90 or higher. Unleaded
gasoline can extend spark plug life and exhaust component life.
Engine Oil
Use of high quality 4-stroke engine oil would extend the lifetime of
the engine. Grade SE or SD engine oil in API method is recommended,
whose viscosity is SAE10W-40. If this oil is not available, please purchase
appropriate substitutes according to the data listed below.
Transmission Oil
Use good quality SAE 10W-40 multi-grade motor oil.
14
Break-in of new motorcycle
Break-in of New Motorcycle
The first 1000km are the most important in the life of your motorcycle.
Proper break-in operation during this period will help ensure maximum life
and performance from your new motorcycle. The parts are manufactured of
high quality materials, and machined parts are finished to close tolerances.
Proper break-in operation allows the machined surfaces to polish each
other and mate smoothly.
Maximum Throttle Operation Recommendation
This table shows the maximum recommended throttle operation
during the break-in period.
Initial 800km
Initial 1600km
Less than 1/2 throttle
Less than 3/4 throttle
Vary the engine Speed
The engine speed should be varied and not held at a constant speed.
This allows the parts to be “loaded” with pressure, and then unloaded,
allowing the parts to cool. This aids the mating process of the parts. It is
essential that some stress be placed on the engine component during
break-in ensure this mating process. Do not, though, apply extensive load
on the engine.
Avoiding Constant Low Speed
It is not benefit to break-in the engine to operate it at a constant low
speed. Allow the engine to accelerate freely within the recommended
maximum limits. Do not, however, use full throttle for the first 1600km.
Allow the Engine Oil to Circulate before Riding
Allow sufficient idling time after warm or cold engine start up before
applying load or revving up the engine. This allows time for the lubricating
oil to reach all critical engine components.
Perform the Foremost Service
The 1000km service is the most important service your motorcycle
will receive. During break-in all of the engine components will have worn
in and all of other parts will have seated in. All adjustments will be restored,
15
Break-in of new motorcycle
all fasteners will be tightened, and the dirty oil will be replaced.
Timely performance of the 1000km service will ensure optimum
service life and performance from the engine.
Caution
The 1000km service should be performed as the outlined in the
inspection and maintenance section in this manual. Pay attention to the
caution and warning in that section.

It is most advisable to reduce the speed slowly by gradual application
of the brakes.
Caution
Single braking of the front or rear wheel may cause the danger of side
slide.
Hurried braking or sharp turning are the major causes of side slides or
overturn, and are therefore extremely dangerous.
7. Special care should be taken in rainy and snowy days.
Moist and wet road surface may cause danger. Sharp turning in the
course of acceleration should be avoided. An appropriate distance should
be kept from the vehicles ahead. Bear in mind that the braking distance in
rainy days is twice as much as in sunny days.
Side sliding is apt to occur on wet road, therefore you'd better
concentrate yourself and get ready to apply the brakes at any time.
8. Check the brakes after flushing or riding in water.
After flushing or riding in water boggles, the braking effect may be
reduced. If this occurs, slow riding and gentle braking should be observed
before the brakes restore normal function.
20

Inspection and Maintenance
Inspection and Maintenance
The maintenance schedule indicates the intervals between periodic
services in kilometers and months. At the end of each interval, be sure to
inspect, check, lubricate and service as instructed. If your motorcycle is
used under heavy load conditions such as continuous full throttle operation
or is operated in a dusty climate, certain services should be performed more
often to ensure reliability of the machine as explained in the maintenance
section. The dealer can provide you with further guidelines. Steering
components, suspensions and wheel components are key items and require
very special and careful servicing. For maximum safety we suggest that
you have these items inspected and serviced by your dealer or a qualified
service mechanic.
The first maintenance
The maintenance after first 1000 km is the most important. During
running in, all engine parts have been fitted each other, together with other
parts. Then, all parts should be readjusted; all fasteners retighten and
contaminated engine oil replaced.
To guarantee the engine with a long service life and a good
performance, carry out the 1000 km maintenance timely.
Caution
You may replace some components when you maintain your
motorcycle. We suggest you use genuine replacement parts or their
equivalent. If you are an expert or a do-it-yourself mechanic, we
recommends that those items on the maintenance schedule marked with an
asterisk (*), be performed by authorized the dealer or qualified service
mechanic. You may perform the unmarked items easily by referring to the
instructions in this section.

porcelain tip. The color can tell you whether or
25
Inspection and Maintenance
not the standard spark plug is suitable for your type of usage. If the
standard spark plug is very black, you’d better use a high-pressure hot type
of spark plug. A normal operating spark plug should be light brown or tan
in color. If the color is white or seem flashing, it is used in overheat
condition and change it with a cold type one.
Caution
Don’t tighten the spark strongly or make screw thread interlock. In
order not to damage the cylinder head, do not allow the contamination
to enter the engine through spark plug hole.
The standard spark plug for this motorcycle has been carefully
selected to meet the vast majority of all operation ranges. If the spark
plug color indicates that other than standard spark plug should be
used, it is best to consult the dealer before selecting an alternate plug
or heat range. The selection of an improper spark plug can lead to
severe engine damage.
Air Filter
The air filter element used in this motorcycle is a polyurethane foam
element. If the filter element has become clogged with dust, intake
resistance will increase with a resultant decrease in power output and
increase in fuel consumption due to the richer mixture. Check and clean the
air filter element according to the following procedure.
1. Remove the two screws.
2. Remove the two fixing slippers by sliding them rearward.
3. Remove the air filter cover.
4. Remove the filter element.

NEVER OPREATE THE ENGINE WITHOUT THE FILTER
ELEMENT. Operating the engine without the filter element will
increase engine wear. Always be sure that the filter element is in
excellent operational condition at all times. The life of the engine
depends largely on this single component.
Carburetor
Undisturbed carburetion is the basis of the performance you ought to
expect of your engine. The carburetor is factory set for the best carburetion.
Do not attempt to alter its setting. There are two items of adjustment,
however, under your care: engine idle speed and throttle cable play. Adjust
the carburetor idle speed end throttle cable play periodically.
Engine Idle Speed Adjustment
1. Start up the engine and warm it up.
2. After engine warms up, turn the throttle stop screw in or out 50
that engine may run at 1700~1900rpm.
If you have a tachometer, you can do this adjustment by referring to
the procedures described above. The engine idle speed should be adjusted
after the engine warms up.
27
Inspection and Maintenance
Throttle Cable Adjustment
1. Loosen the lock nut .
2. Adjust the cable slack by turning adjuster in or out to obtain the
correct slack of 0.5~1.0mm.
3. After adjusting the slack, tighten the lock nut.
Tires
Check the tire inflation pressure and tire treed condition. For
maximum safety and good tire life, the tire pressures should be inspected
more often.
Tire Pressure
Insufficient air pressure in the tires not only hastens tire wear but also
seriously affects the stability of the motorcycle. Under inflated tires make
smooth cornering difficult and over inflated tires decrease the amount of
tire in contact with the ground, which can lead to skids and loss of control.
Be sure that the tire pressure is within the specified limits at all times. Tire
pressure should only be adjusted when the tires are cold.
Cold inflation tire pressure
Front Wheel 225kPa(2.25bars)
Rear Wheel
280kPa(2.80bars)
Caution
Tire inflation pressures and the general tire conditions are extremely
important to the proper performance and safety of the motorcycle. Cheek
your tires frequently for both wear and inflation pressures
Tire Tread Condition
28
Error! Use the Home tab to apply 标题 1 to the text that you want to appear here.
Operating the motorcycle with excessively worn tires will decrease
riding stability and can lead to loss of control. It is recommended that a tire
be replaced when the remaining depth of tire tread becomes 1.6mm or less.
Caution
The standard tires on your motorcycle are 3.50-10 4PR in front and
rear. The use of a tire other than standard may cause trouble.
Brake circuits
The front brake tank is located in the handlebar, near the throttle grip.
The Rear brake tank is located behind the rear brake pedal.
Follow the setps indicated int this procedure:
1. Keep the vehicle in vertical position with the handlebar centered.
2. The oil level lowers because of the brake pads are worn. In case
that the level is owern than the minimun, refer to the nearest Distributor to
perform a control of the brake system.
Refilling the fluid
Use only the specified brake fluid DOT 4
Follow the next operations:
1. Keep the vehicle in vertical position with the handlebar centered.
2. Remove the tank cap by loosing the securing bolts.
3. Fill up the fluid at correct level, use only the specified liquid.
4. Install the cover in the reverse order of removal.
Warning
The circuit of the brake fluid is dangerous. In case of accidental
contact, clean immediately with water the affected parts.
Caution
Make sure there is no leakage in the circuit and check that the hoses
and the unions are not damaged and also they should not be twisted.
Warning
The adjustment of the brake pump has been done at the factory; if
necessary, go to your nearest Dealer. It is forbidden to change these
adjustments, because it can seriously damage the brake system.
Caution
The brake circuit fluid is highly corrosive, avoid contact with the
body, painted parts and and/or any plastic parts.
29
Inspection and Maintenance
Warning
The brake circuit fluid is hygroscopic( it absorbs the moisture). If the
moisture of the brake fluid is higher than its specified value, the brakes will
not work properly.
Under normal weather conditions, the brake fluid must be replaced
every 2 years. For this operation which needs an special care, go to your
nearest dealer.
Fuel Hose
Replace the fuel hoses every four years.
Fuse
The fuse is located nest to the battery. If there is any electrical system
failure, first check the fuse. In the case the fuse blows, there is a 10A spare
fuse.
Caution
Always be sure to replace the blown fuse with the correct amperage
fuse. Never use substitute, for example aluminum foil or wire, to replace a
blown fuse. If the spare fuse installed blows in a short period of time, it
means that you could have a major electrical problem. You should consult
the dealer or a qualified service mechanic immediately.

Trouble Shooting
Trouble Shooting
If the engine refuses to start, perform the following inspections to
determine the cause.
1. Is there enough fuel in the fuel tank?
2. Is there fuel reaching the carburetor from the fuel tank?
3. Loosen the carburetor drain plug and drain the fuel in the
carburetor. Refit the drain plug.
4. Depress the kick-starter lever several times.
5. Loosen the drain plug and check that the fuel is in the carburetor.
6. If it has been determined that fuel is reaching the carburetor, the
ignition system should be checked next.
Caution
Do not allow the fuel to spill. Do not allow any fuel to come in contact
with the hot engine or exhaust system. Extinguish any smoking materials
by from any other fire or heat source.
1. Remove the spark plug and reattach it to the spark plug lead.
2. While holding the spark plug firmly against the engine, crank the
engine with the ignition switch in ON position. If the ignition
system is operating properly, a blue spark should jump across the
spark plug gap. If there is no spark, consult the dealer for
repairs.
Caution
Do not hold the spark plug close to the open spark plug hole in the
cylinder head as gasoline vapor inside the cylinder could be ignited,
creating a fire hazard.
To reduce the chance of electrical shock, hold the metal shell of the
spark plug against an unpainted metal portion of the engine. Due to the
possibility of electrical shock, anyone with a heart condition or pacemaker
should avoid this check.
Engine Stalling
1. Check the fuel supply in the fuel tank.
2. Check the ignition system for intermittent spark.
3. Check the engine idle speed.
Caution
It is best to consult the dealer before attempting to troubleshoot any
problem. If the machine is still within the warranty, then the dealer should
definitely be consulted before you attempt any repairs on the machine.
Tampering with the machine by yourself while in warranty may affect
warranty consideration.
