Steering inspectionPeriodically inspect the condition of the
steering. Worn out or loose steering
bearings may be dangerous. Place a
stand under the engine to raise the
front wheel off the ground. Hold the
lower end of the front forks and try to
move them forward and backward. If
any free play can be felt, ask a Yamaha
dealer to inspect and adjust the steer-
ing. Inspection is easier if the front
wheel is removed.

WARNING
@ Securely support the motorcycle so
there is no danger of it falling over. @
EAU01144
Wheel bearingsIf there is play in the front or rear wheel
hub or if the wheel does not turn
smoothly, have a Yamaha dealer in-
spect the wheel bearings.

BatteryThis motorcycle is equipped with a
sealed-type battery. Therefore it is not
necessary to check the electrolyte or fill
the battery with distilled water.l
If the battery seems to have dis-
charged, consult a Yamaha deal-
er.

If the motorcycle is equipped with
optional electrical accessories, the
battery tends to discharge more
quickly, so be sure to recharge it
periodically.

Fuse replacementThe fuse box is located under the seat.
(See page 3-11 for seat removal and
installation procedures.)
If any fuse is blown, turn off the main
switch and the switch of the circuit in
question. Install a new fuse of specified
amperage. Turn on the switches and
see if the electrical device operates. If
the fuse immediately blows again, con-
sult a Yamaha dealer.
EC000103
CAUTION:@ Do not use fuses of higher amper-
age rating than those recommend-
ed. Substitution of a fuse of
improper rating can cause extensive
electrical system damage and pos-
sibly a fire. @

7-MOTORCYCLE CARE AND STORAGECareThe exposure of its technology makes
a motorcycle charming but also vulner-
able. Although high-quality compo-
nents are used, they are not all rust-re-
sistant. While a rusty exhaust pipe may
remain unnoticed on a car, it does look
unattractive on a motorcycle. Frequent
and proper care, however, will keep
your motorcycle looking good, extend
its life and maintain its performance.
Moreover, the warranty states that the
vehicle must be properly taken care of.
For all these reasons, it is recommend-
ed that you observe the following
cleaning and storing precautions.Before cleaning
1. Cover up the muffler outlets with
plastic bags.
2. Make sure that all caps and covers
as well as all electrical couplers
and connectors, including the
spark plug caps, are tightly in-
stalled.
3. Remove extremely stubborn dirt,
like oil burnt onto the crankcase,
with a degreasing agent and a
brush, but never apply such prod-
ucts onto seals, gaskets, sprock-
ets, the drive chain and wheel
axles. Always rinse the dirt and
degreaser off with water.Cleaning
After normal use
Remove dirt with warm water, a neutral
detergent and a soft clean sponge,
then rinse with plenty of clean water.
Use a tooth or bottle brush for hard-to-
reach parts. Tougher dirt and insects
will come off more easily if the area is
covered with a wet cloth for a few min-
utes before cleaning.
