3. Thoroughly lubricate the drive chain with a
special O-ring chain lubricant.
cCDo not use engine oil or any other lubricants
for the drive chain, as they may contain sub-
stances that could damage the O-rings.

EBU00570Cable inspection and lubricationwInspect cables frequently and replace if dam-
aged. Corrosion can result when the outer
covering of control cables becomes dam-
aged. Cables can also become frayed or
kinked. Operation of controls could be
restricted, which could cause an accident or
injury.Lubricate the inner cables and the cable ends. If
the cables do not operate smoothly, ask a
Yamaha dealer to replace them.
Recommended lubricant:
Engine oil

Engine overheatingWait until the
engine has cooled.
Check the coolant level in the
reservoir tank and/or radiator.
Level is OK.Level is low, check the
cooling system for leakage.
No
leakage.Leakage.
Ask a Yamaha dealer
to inspect and repair
the cooling system.Add coolant.
(See NOTE.)
Restart the engine. If the engine overheats
again, ask a Yamaha dealer to inspect and
repair the cooling system.
NOTE:If it is difficult to get recommended coolant, tap water can be temporarily used, provided that it is
changed to the recommended coolant as soon as possible.wWait for the engine and radiator to cool before removing the radiator cap. You could be burned
by hot fluid and steam blown out under pressure. Always put a thick rag over the cap when
opening. Allow any remaining pressure to escape before completely removing the cap.

CLEANING AND STORAGE
A. CLEANING
Frequent, thorough cleaning of your machine
will not only enhance its appearance but will
improve its general performance and extend the
useful life of many components.
1. Before cleaning the machine:
a. Block off the end of the exhaust pipe to
prevent water entry. A plastic bag and
strong rubber band may be used.
b. Make sure the spark plugs and all filler
caps are properly installed.
2. If the engine case is excessively greasy,
apply degreaser with a paint brush. Do not
apply degreaser to the chain, sprockets or
wheel axles.
3. Rinse the dirt and degreaser off with a gar-
den hose. Use only enough pressure to do
the job.

7. Clean the seat with a vinyl upholstery
cleaner to keep the cover pliable and
glossy.
8. Automotive type wax may be applied to all
painted and chrome plated surfaces.
Avoid combination cleaner-waxes. Many
contain abrasives which may mar the paint
or protective finish.
When finished, start the engine and let it
idle for several minutes.wWet brakes may have reduced stopping abili-
ty, increasing the chance of an accident.
Test the brakes after washing. Apply the
brakes several times at slow speeds to let
friction dry out the linings.

EBU00529B. STORAGE
Long term storage (60 days or more) of your
machine will require some preventive proce-
dures to guard against deterioration. After thor-
oughly cleaning the machine, prepare for stor-
age as follows:
1. Drain the fuel tank, fuel lines and carbure-
tor float bowls.
2. Remove the spark plugs, pour about one
tablespoon of SAE 10W30 or 20W40
motor oil in the spark plug holes and rein-
stall the spark plugs. Ground the spark
plug wires and turn the engine over several
times to coat the cylinder walls with oil.
3. Clean the drive chain thoroughly and lubri-
cate it. (See page 8-95 for details.)
Reinstall the chain or store it in a plastic
bag tied to frame for safekeeping.
4. Lubricate all control cables.

cCBe sure to use motor oils that do not contain
anti-friction modifiers. Passenger car motor
oils (often labeled “Energy Conserving”)
contain anti-friction additives which will
cause clutch and/or starter clutch slippage,
resulting in reduced component life and poor
engine performance.
