Oil pressure check
1. Put a cloth around the cylinder.
2. Slightly loosen the oil gallery bolt in the
cylinder head.
3. Start the engine and keep it idling until oil
begins to seep from the oil gallery. If no oil
comes out after one minute, turn the en-
gine off so it will not seize and find the
cause.
4. Start the engine, and then check the oil
pressure.
5. After checking, tighten the oil gallery bolt
to the specified torque.CAUTION:Be sure to check the oil pressure after replac-ing the engine oil. Tightening torque:
Oil gallery bolt:
7 Nm (0.7 m·kg)

6. Inspect the element. If damaged, replace
it.
7. Apply SAE 10W30 motor oil to the ele-
ment.NOTE:The element should be wet but not dripping.
8. Apply all-purpose grease to the air filter
element seat.
9. Reinstall the element to the element
guide.
10. Reinstall the element assembly and parts
removed for access.NOTE:The air filter element should be cleaned every
20 ~ 40 hours. It should be cleaned and lubri-
cated more often if the machine is operated in
extremely dusty areas. Each time filter element
maintenance is performed, check the air inlet
to the filter case for obstructions. Check the air
cleaner rubber joint to the carburetor and man-
ifold fittings for an airtight seal. Tighten all fit-
tings securely to avoid the possibility ofunfiltered air entering the engine.

3. Refill with the same type of brake fluid.
Mixing fluids may result in a harmful
chemical reaction and lead to poor brake
performance.
4. Be careful that water does not enter the
master cylinder when refilling. Water will
significantly lower the boiling point of the
fluid and may result in vapor lock.
5. Brake fluid may deteriorate painted sur-
faces or plastic parts. Always clean up
spilled fluid immediately.
6. Have a Yamaha dealer check the cause if
the brake fluid level goes down.

Drive chain cleaning and lubrication
The drive chain is equipped with rubber
O-rings between the chain plates. Steam clean-
ing, high-pressure washes, and certain sol-
vents can damage these O-rings. Use only
kerosene to clean the drive chain. Wipe it dry,
and thoroughly lubricate it with SAE 30 ~ 50
motor oil. Do not use any other lubricants on
the drive chain. They may contain solvents that
could damage the O-rings.

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, whichcould 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.

WARNING
Battery electrolyte is poisonous and danger-
ous, causing severe burns, etc. It contains sul-
furic acid. Avoid contact with skin, eyes or
clothing.
Antidote:
EXTERNAL: Flush with water.
INTERNAL: Drink large quantities of water or
milk. Follow with milk of magnesia, beaten
egg or vegetable oil. Call a physician immedi-
ately.
EYES: Flush with water for 15 minutes and get
prompt medical attention. Batteries produce
explosive gases. Keep sparks, flame, ciga-
rettes or other sources of ignition away. Venti-
late when charging or using in an enclosed
space. Always shield your eyes when working
near batteries. KEEP OUT OF REACH OF CHIL-DREN.

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. Clean the drive chain thoroughly and lu-
bricate it. (See page 8-61.)
4. Lubricate all control cables.

5. Block up the frame to raise all wheels off
the ground.
6. Tie a plastic bag over the exhaust pipe
outlet to prevent moisture from entering.
7. If storing in a humid or salt-air atmo-
sphere, coat all exposed metal surfaces
with a light film of oil. Do not apply oil to
any rubber parts or the seat cover.
8. 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 ex-
cessively warm or cold place (less than
0 ˚C or more than 30 ˚C).
NOTE:

Make any necessary repairs before storing the
machine.
