TroubleshootingAlthough Yamaha motorcycles receive
a rigid inspection before shipment from
the factory, trouble may occur during
operation.
Any problem in the fuel, compression,
or ignition systems can cause poor
starting and loss of power. The trou-
bleshooting 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 motor-
cycle. 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.

ECA00010CAUTION:
l
Avoid using strong acidic
wheel cleaners, especially on
spoked wheels. If you do use
such products for hard-to-re-
move dirt, do not leave it on any
longer than instructed, then
thoroughly rinse it off with wa-
ter, immediately dry the area
and apply a corrosion protec-
tion spray.
l
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.
l
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 abrasive
cleaning products, solvent or
thinner, fuel (gasoline), rust re-
movers or inhibitors, brake flu-
id, antifreeze or electrolyte.
l
Do not use high-pressure
washers or steam-jet cleaners
since they cause water seep-
age and deterioration in the fol-
lowing areas: seals (of wheel
bearings, swingarm bearings,
forks and brakes), electric com-
ponents (couplers, connectors,
instruments, switches and
lights), breather hoses and
vents.
l
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 plastic may
leave scratches on the wind-
shield. Test the product on a
small hidden part of the wind-
shield to make sure they do not
leave any marks. If the wind-
shield is scratched, use a quali-
ty plastic polishing compound
after washing.
After riding in the rain, near the sea or
on salt-sprayed roadsSince sea salt or salt sprayed on the
roads in the winter are extremely corro-
sive 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.)

Storage
Short-term
Always store your motorcycle in a cool,
dry place and, if necessary, protect it
against dust with a porous cover.
ECA00014
CAUTION:

l
Storing the motorcycle in a
poorly ventilated room or cov-
ering it with a tarp while it is still
wet will allow water and humid-
ity to seep in and cause rust.
l
To prevent corrosion, avoid
damp cellars, stables (because
of the presence of ammonia)
and areas where strong chemi-
cals are stored.Long-term
Before storing your motorcycle for sev-
eral months:
1. Follow all the instructions in the
“Care” section of this chapter.
2. Drain the carburetor float cham-
bers by loosening the drain bolts;
this will prevent fuel deposits from
building up. Pour the drained fuel
into the fuel tank.
3. Only for motorcycles equipped
with a fuel cock which has an
“OFF” position: Turn the fuel cock
to “OFF”.
4. Fill up the fuel tank and add fuel
stabilizer (if available) to prevent
the fuel tank from rusting and the
fuel from deteriorating.
5. Perform the following steps to
protect the cylinders, piston rings,
etc. from corrosion.
a. Remove the spark plug caps and
spark plugs.
b. Pour a teaspoonful of engine oil
into each spark plug bore.c. Install the spark plug caps onto
the spark plugs and place the
spark plugs on the cylinder head
so that the electrodes are ground-
ed. (This will limit sparking during
the next step.)
d. Turn the engine over several
times with the starter. (This will
coat the cylinder walls with oil.)
e. Remove the spark plug caps from
the spark plugs, install the spark
plugs and then the spark plug
caps.
EWA00003
WARNING

When turning the engine over, be
sure to ground the spark plug elec-
trodes to prevent damage or injury
from sparking.
6. Lubricate all control cables and
the pivoting points of all levers and
pedals as well as of the side-
stand/centerstand.

CAUTION:Be sure to use motor oils that do not contain anti-fric-
tion modifiers. Passenger car motor oils (often labeled
“Energy Conserving”) contain anti-friction additives
which will cause clutch and/or starter clutch slippage,
resulting in reduced component life and poor engineperformance.
