TroubleshootingAlthough Yamaha motorcycles
receive a rigid inspection before ship-
ment 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, experi-
ence, and know-how to properly ser-
vice your motorcycle. Use only gen-
uine 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.

Improper cleaning can damage
windshields, cowlings, panels
and other plastic parts. Use
only a soft, clean cloth or
sponge with mild detergent
and water to clean plastic.
8 8
Do 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, sol-
vent or thinner, fuel (gasoline),
rust removers or inhibitors,
brake fluid, antifreeze or elec-
trolyte.8 8
Do not use high-pressure
washers or steam-jet cleaners
since they cause water seep-
age and deterioration in the
following areas: seals (of
wheel bearings, swingarm
bearings, forks and brakes),
electric components (cou-
plers, connectors, instru-
ments, switches and lights),
breather hoses and vents.
8 8
For motorcycles equipped
with a windshield: Do not use
strong cleaners or hard
sponges as they will cause
dulling or scratching. Some
cleaning compounds for plas-
tic may leave scratches on the
windshield. Test the product
on a small hidden part of the
windshield to make sure they
do not leave any marks. If the
windshield is scratched, use a
quality plastic polishing com-
pound after washing.
After riding in the rain, near the seaor on salt-sprayed roadsSince sea salt or salt sprayed on the
roads in the winter are extremely cor-
rosive in combination with water,
carry out the following steps after
each ride in the rain, near the sea or
on salt-sprayed roads. (Salt sprayed
in the winter may remain on the roads
well into spring.)
1.Clean your motorcycle with cold
water and soap after the engine
has cooled down.
ECA00012
cCDo not use warm water since it
increases the corrosive action of
the salt.2.Be sure to apply a corrosion pro-
tection spray on all (even
chrome- and nickel-plated) metal
surfaces to prevent corrosion.

9After cleaning
1.Dry the motorcycle with a
chamois or an absorbing cloth.
2.Immediately dry the drive chain
and lubricate it to prevent it from
rusting.
3.Use a chrome polish to shine
chrome, aluminum and stainless-
steel parts, including the exhaust
system. (Even the thermally
induced discoloring of stainless-
steel exhaust systems can be
removed through polishing.)
4.To prevent corrosion, it is recom-
mended to apply a corrosion pro-
tection spray on all (even
chrome- and nickel-plated) metal
surfaces.
5.Use spray oil as a universal
cleaner to remove any remaining
dirt.
6.Touch up minor paint damage
caused by stones, etc.
7.Wax all painted surfaces.
8.Let the motorcycle dry complete-
ly before storing it or covering it.
EWA00001
wMake sure that there is no oil or
wax on the brakes and tires. If nec-
essary, clean the brake discs and
linings with a regular brake disc
cleaner or acetone, and wash the
tires with warm water and mild
soap. Then, carefully test the
motorcycle for its braking perfor-
mance and cornering behavior.

Apply spray oil and wax spar-
ingly and wipe off any excess.
8 8
Never apply oil or wax on rub-
ber and plastic parts, but treat
them with a suitable care prod-
uct.
8 8
Avoid using abrasive polish-
ing compounds as they wear
away the paint.
NOTE:
Consult a Yamaha dealer for advice
on what products to use.
