Engine oil
1. Engine oil level measurement
a. Place the machine on a level place.
b. Warm up the engine for several minutes
and stop it.
c. With the engine stopped, check the oil lev-
el through the level window located at the
lower part of the left side crankcase cover.
NOTE:
Wait a few minutes until the oil level settles be-
fore checking.
d. The oil level should be between the maxi-
mum and minimum marks. If the level is
low, fill engine with sufficient oil to raise it
to the specified level.
CAUTION:
Be sure no foreign material enters the crank-
case.

3. Remove the air filter element, and sepa-
rate it from the guide.
4. Wash the element gently but thoroughly
in solvent.
WARNING
Always use parts cleaning solvent to clean the
air filter element. Never use low flash point
solvents or gasoline to clean the air filter ele-
ment because the engine could catch fire or
explode.
5. Squeeze the excess solvent out of the fil-
ter and let it dry.
CAUTION:
Do not twist the filter element when squeez-
ing it.
6. Inspect the element. If damaged, replace
it.
7. Apply SAE10W30 motor oil to the ele-

Cable inspection and lubrication
WARNING
Inspect cables frequently and replace if dam-
aged. Corrosion can result when the outer
covering of control cables becomes damaged.
Cables can also become frayed or kinked. Op-
eration 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.

Engine oil
Recommended lubricant:
Lithium-soap-based grease
(all-purpose grease)

B. STORAGE
Long term storage (60 days or more) of your
machine will require some preventive proce-
dures to guard against deterioration. After
thoroughly cleaning the machine, prepare for
storage as follows:
1. Fill the fuel tank with fresh fuel and add
fuel stabilizer (if available).
NOTE:
Use of fuel stabilizer eliminates the need to
drain the fuel system. Consult a Yamaha dealer
if the fuel system is to be drained instead.
2. Remove the spark plug, pour about one
tablespoon of SAE 10W30 or 20W40 mo-
tor oil in the spark plug hole and reinstall
the spark plug. Ground the spark plug
wire and turn the engine over several
times to coat the cylinder wall with oil.
3. Lubricate all control cables.
4. Block up the frame to raise all wheels off
the ground.

CAUTION:
Be 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.
