inspectionThere should be a free play of 4 ~
6 mm at the throttle grip. If the free play
is incorrect, ask a Yamaha dealer to
make this adjustment.

Valve clearance adjustmentThe correct valve clearance changes
with use, resulting in improper fuel/air
supply or engine noise. To prevent this,
the valve clearance must be adjusted
regularly. This adjustment however,
should be left to a professional
Yamaha service technician.

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 trouble-
shooting 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 of-
ten inferior. Consequently, they have a
shorter service life and can lead to ex-
pensive repair bills.

CAUTION:@ l
Avoid using strong acidic wheel
cleaners, especially on spoked
wheels. If you do use such
products for hard-to-remove
dirt, do not leave it on any long-
er than instructed, then thor-
oughly rinse it off with water,
immediately dry the area and
apply a corrosion protection
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 wash-
ers or steam-jet cleaners since
they cause water seepage and
deterioration in the following ar-
eas: seals (of wheel bearings,
swingarm bearings, forks and
brakes), electric components
(couplers, connectors, instru-
ments, 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.

CAUTION:@ l
Apply spray oil and wax spar-
ingly and wipe off any excess.
l
Never apply oil or wax on the
drive belt.
l
Never apply oil or wax on rub-
ber and plastic parts, but treat
them with a suitable care prod-
uct.
l
Avoid using abrasive polishing
compounds as they wear away
the paint.
@NOTE:@ Consult a Yamaha dealer for advice on
what products to use. @
StorageShort-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 cover-
ing it with a tarp while it is still
wet will allow water and humidi-
ty 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
several 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 pro-
tect the cylinders, piston rings, etc.
from corrosion.

“Energy Conserving”) contain anti-friction additives which
will cause clutch and/or starter clutch slippage, resulting in
reduced component life and poor engine performance.
