Replenishing the battery fluid
A poorly maintained battery will corrode
and discharge quickly. The battery fluid
should be checked at least once a month.
The level should be between the minimum
and maximum marks. Use only distilled
water if refilling is necessary.
EUU33800
cC
Normal tap water contains minerals which
are harmful to a battery; therefore, refill
only with distilled water.
EUU65901
w
Take care not to spill battery fluid on the
chain. Battery fluid may weaken the chain
causing shorter chain life and possibly re-
sult in an accident.

Fuse replacement
1. The fuse case is located inside the
right sidecover.
2. If a fuse is blown, turn off the ignition
switch and the switch of the circuit in
question. Install a new fuse of proper
amperage. Turn on the switches and
see if the electrical device operates. If
the fuse immediately blows again,
consult a Yamaha dealer.
EUU34400
cC
Do not use fuses of higher amperage rating
than those recommended. Substitution of a
fuse of improper rating can cause extensive
electrical system damage and possibly a
fire.

Troubleshooting
Although Yamaha motorcycles receive a
rigid inspection before shipment from the
factory, trouble may occur during opera-
tion. If your motorcycle requires any repair,
bring it to a Yamaha dealer. The skilled
technicians at a Yamaha dealership have
the tools, experience, and know-how to
properly service your motorcycle. Use only
genuine Yamaha parts on your motorcycle.
Imitation parts may look like Yamaha parts,
but they are often inferior. Consequently,
they have a shorter service life and can
lead to expensive repair bills.

CLEANING AND
STORAGE
EAK01302*
A. CLEANING
Frequent, thorough cleaning of your mo-
torcycle will not only enhance its appear-
ance but will improve its general perfor-
mance and extend the useful life of many
components.
1. Rinse the dirt and degreaser off with a
garden hose.
EUU34602
cC
Excessive hose pressure may cause water
seepage and deterioration of wheel bear-
ings, front fork, brakes, transmission seals
and electrical parts.
2. After cleaning the motorcycle, dry all
surfaces with a chamois, clean towel,
or soft absorbent cloth.3. Dry the chain and lubricate it to pre-
vent rust.
4. Automotive-type wax may be applied
to all painted and chrome-plated sur-
faces. When finished, start the engine
and let it idle for several minutes.
EAK00700
B. STORAGE
Long term storage (60 days or more) of
your motorcycle will require some preven-
tive procedures to guard against deteriora-
tion. After thoroughly cleaning the motor-
cycle, prepare for storage as follows:
1. Drain the fuel tank, fuel lines, and car-
buretor float bowl(s).
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.
67

3. Remove the drive chain. Thoroughly
clean the chain with solvent and lubri-
cate it. Reinstall the chain or store it in
a plastic bag (tied to frame for safe-
keeping).
4. Lubricate all control cables.
5. Block up the frame to raise both
wheels off the ground.
6. Tie a plastic bag over the exhaust pipe
outlet to prevent moisture from enter-
ing.
7. If storing in a humid or salt-air atmos-
phere, 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 bat-
tery in an excessively warm or cold
place (less than 0°C (32°F) or more
than 30°C (86°)).
EUU05800
NOTE:
Make any necessary repairs before storing
the motorcycle.
