If any damage or unsmooth move-
ment is found with the front fork,
consult a Yamaha dealer.
EAU00794Steering inspection
Periodically inspect the condition
of the steering. Worn out or loose
steering bearings may be danger-
ous. 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
steering. Inspection is easier if the
front wheel is removed.

EAU01008Troubleshooting
Although Yamaha motorcycles
receive a rigid inspection before
shipment from the factory, trouble
may occur during operation.
Any problem in the fuel, compres-
sion, or ignition systems can cause
poor starting and loss of power.
The troubleshooting chart
describes a quick, easy procedure
for making checks.
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 expen-
sive repair bills.

EAU01301A. CLEANING
Frequent, thorough cleaning of
your motorcycle will not only
enhance its appearance but will
improve its
general performance and extend
the useful life of many compo-
nents.
ECA00002

8Improper cleaning can damage
the cowlings, panels and other
plastic parts. Use only a soft,
clean cloth or sponge with
mild detergent and water to
clean plastic.
8Do not use any harsh chemical
products on plastic parts. Be
sure to avoid using cloths or
sponges which have been in
contact with strong or abra-
sive cleaning products, solvent
or thinner, fuel (gasoline), rust
removers or inhibitors, brake
fluid, antifreeze or electrolyte.
EC000111
cC
Excessive hose pressure may
cause water seepage and deterio-
ration of wheel bearings, front
fork, brakes, transmission seals
and electrical parts.
Many expensive repair bills have
resulted from improper high pres-
sure detergent applications such
as those available in coin-operated
car washers.
4. After riding on salted roads,
wash the motorcycle with cold
water immediately. Do not use
warm water as it increases the
chemical reaction of the salt.
5. Once the majority of the dirt
has been hosed off, wash all
surfaces with warm water and
mild, detergent-type soap. An
old toothbrush or bottle brush
is handy for hard-to-get-at
places. 1. Before cleaning the motorcy-
cle:
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 plug and
all filler caps are properly
installed.
2. If the engine case is excessive-
ly 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 garden hose. Use
only enough pressure to do
the job.
