ROAD SAFETY TIPS
SAFE RIDING
1. Before riding, you should learn to ride your motorcycle properly and all the control functions should be known
to you.
2. Remember that there are no legal “rights” when it comes to survival as far as Motorcyclists are
concerned. The fact that you may be well within your rights is no guarantee that you will avoid a collision with
a bigger vehicle whose driver fails to see you. Always ride defensively and take nothing on road for granted.
3. Develop the ability to react swiftly to any unexpected road hazards or emergencies giving yourself time to
spare for appropriate response.
4. Develop the ability to get the most out of your Motorcycle, But at the same time get to know its capabili-
ties and limitations.
5. Ride thoughtfully, planning your route well in advance.
6.Give proper Signals and use Horn and Headlights judiciously.
7. Don’t ride in another motorist’s blind spot.
8. Always make pre-ride safety checks before you start the Engine.
SAFE BRAKING
Use the basic methods of braking effectively.
1. Engine Brake : When the Throttle is released, compression backs up and acts as the Engine Brake.
If the riding condition allows, reduce speed by shifting the Gear down.
2. Front and Rear Brakes : It is important to apply equal force to the Front and Rear Brakes simultaneously.
• Use Front and Rear Brakes simultaneously.
• Be sure not to disengage the clutch while braking.
• While riding downhill always use Engine as a Brake and never ride in Neutral Gear.
• While riding down hill do not switch off ignition while Engine is in gear. CAUTION :

run for any length of time in a
closed area. The exhaust fumes
are poisonous and can cause
loss of consciousness.
Always operate your
Motorcycle in an area with
adequate ventilation.
3. Before starting out, always be
sure the side stand is up.

Idle speed adjustmentA diagnostic tachometer must be
used for this procedure.
1. Attach the tachometer. Start the
engine and warm it up for a few
minutes at approximately 1,300
to 1,500 r/min. Occasionally rev
the engine to 4,000 to 5,000
r/min. The engine is warm when it
quickly responds to the throttle.
1. Throttle stop screw2. Set the idle to the specified
engine speed by adjusting the
throttle stop screw. Turn the
screw in direction a to increase
engine speed and in direction b
to decrease engine speed.
Standard idle speed:
1,300 ~ 1,500 r/min
If the specified idle speed cannot be
obtained by performing the above
adjustment, consult a
dealer.YAMAHA
Throttle cable free play
adjustmentBefore checking the throttle cable
free play, the engine idling speed
should be adjusted.

Free play:
3 ~ 7mm
PERIODIC MAINTENANCE AND MINOR REPAIR
6-12

Drive chain lubricationThe chain consists of many parts
which work with each other. If the
chain is not maintained properly, it
will wear out quickly. Therefore, the
chain must be serviced regularly.
This service is especially necessary
when riding in dusty areas.
1. The drive chain should be
lubricated every 5,000 km.
2. To clean the chain thoroughly,
remove it from the Motorcycle,
dip it in solvent, and clean out as
much dirt as possible. Then, take
the chain out of the solvent to dry
it, and then dip the chain in oil of
20W40. Remove the chain and
hang it on a peg for a while till the
excess oil drips down completely.
Then using a clean cloth wipe the
chain.
Cable inspection and
lubricationDamage to the outer housing of
cables may lead to internal rusting
and interfere with the cable
movement. Replace damaged
cables as soon as possible to
prevent unsafe conditions.
Lubricate the cables with anti-
corrosive oil and cable ends. If a
cable does not operate smoothly,
ask a YAMAHA dealer to replace it.
Recommended lubricant:
20W40 Type SG
Throttle cable and grip
lubricationThe throttle twist grip assembly
should be greased at the time that
the cable is lubricated, since the
grip must be removed to get at the
end of the throttle cable. After
removing the screws, hold the end
of the cable up in the air and put in
several drops of lubricant. With the
throttle grip disassembled, coat the
metal surface of the grip assembly
with a suitable all purpose grease.
PERIODIC MAINTENANCE AND MINOR REPAIR

WARNING

8. Clean the seat with a vinyl
upholstery cleaner to keep the
cover pliable and glossy.
9. Automotive-type wax may be
applied to all painted and chrome-
plated surfaces. Avoid
combination cleaner waxes. Many
contain abrasive which may mar
the paint or protective finish. When
finished, start the engine and let it
idle for several minutes.
B. STORAGELong term storage (60 days or more)
of your Motorcycle will require some
preventive procedures to guard
against deterioration. After thor-
oughly cleaning the Motorcycle,
prepare for storage as follows:
1. Drain the fuel tank, fuel lines, and
carburetor float bowl.
2. Remove the empty fuel tank, pour
a cup of SAE 10W30 or 20W40
motor oil in the tank, shake the
tank to coat the inner surfaces
thoroughly and drain off the
excess oil. Reinstall the tank.
3. Remove the spark plug, pour
about one tablespoon of SAE
10W30 or 20W40 motor oil in the
spark plug hole and reinstall the
spark plug. Kick the engine over
several times (with the ignition off)
to coat the cylinder wall with oil.
4. Remove the drive chain.
Thoroughly clean the chain withsolvent and lubricate it. Reinstall
the chain or store it in a plastic bag
(tied to frame for safe-keeping).
5. Lubricate all control cables.
6. Block up the frame to raise both
wheels off the ground.
7. Tie a plastic bag over the
exhaust pipe outlet to prevent
moisture from entering.
8. If storing in a humid or salt-air
atmosphere, coat all exposed
metal surfaces with a light film of
oil. Do not apply oil to any rubber
parts or the seat cover.
9. Remove the battery and charge it.
Store it in a dry place and
recharge it once a month. Do not
store the battery in an excessively
warm or cold place (less than 0ºC
or more than Ambient).
Make any necessary repairs before
storing the Motorcycle.
