Checking the throttle grip free
play The throttle grip free play should mea-
sure 3.0–5.0 mm (0.12–0.20 in) at the
inner edge of the throttle grip. Periodi-
cally check the throttle grip free play
and, if necessary, have a Yamaha deal-
er adjust it.
EAU21401
Valve clearance The valve clearance changes with use,
resulting in improper air-fuel mixture
and/or engine noise. To prevent this
from occurring, the valve clearance
must be adjusted by a Yamaha dealer
at the intervals specified in the periodic
maintenance and lubrication chart.
Engine idling speed: 1100–1300 r/min

If a fuse is blown, replace it as follows.
TIPInclude steps 2, 3, 7 and 8 only for the
fuel injection system fuse.1. Turn the key to “OFF” and turn off
the electrical circuit in question. 2. Unhook the battery band, and then
remove the battery cover.
3. Remove the starter relay cover by pulling it upward. 4. Remove the blown fuse, and then
install a new fuse of the specified
amperage. WARNING! Do not
use a fuse of a higher amperage
rating than recommended to
avoid causing extensive dam-
age to the electrical system and
possibly a fire.

To install the rear wheel1. Install the wheel and the brake cal- iper bracket by inserting the wheel
axle from the left-hand side.TIP●
Make sure that the slot in the brake
caliper bracket is fit over the retain-
er on the swingarm.
●
Make sure that there is enough
space between the brake pads be-
fore installing the wheel.
2. Install the drive chain onto the rearsprocket.
3. Install the axle nut. 4. Lower the rear wheel so that it is
on the ground, and then put the
sidestand down.
5. Adjust the drive chain slack. (See page 6-25.)
6. Tighten the axle nut, and then tighten the locknuts to the speci-
fied torques.

Troubleshooting Although Yamaha motorcycles receive
a thorough inspection before shipment
from the factory, trouble may occur dur-
ing operation. Any problem in the fuel,
compression, or ignition systems, for
example, can cause poor starting and
loss of power.
The following troubleshooting charts
represent quick and easy procedures
for checking these vital systems your-
self. However, should your motorcycle
require any repair, take it to a Yamaha
dealer, whose skilled technicians have
the necessary tools, experience, and
know-how to service the motorcycle
properly.
Use only genuine Yamaha replace-
ment parts. Imitation parts may look like
Yamaha parts, but they are often inferi-
or, have a shorter service life and can
lead to expensive repair bills.
WARNING
EWA15141
When checking the fuel system, do
not smoke, and make sure there are
no open flames or sparks in the ar-
ea, including pilot lights from water

7off any detergent residue using
plenty of water, as it is harmful
to plastic parts.
●
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.
●
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 and swing-
arm bearings, fork and brakes),
electric components (couplers,
connectors, instruments,
switches and lights), breather
hoses and vents.
●
For motorcycles equipped with
a windshield: Do not use strong
cleaners or hard sponges as
they will cause dulling or
scratching. Some cleaning com-
pounds for plastic may leave
scratches on the windshield. Test the product on a small hid-
den part of the windshield to
make sure that it does not leave
any marks. If the windshield is
scratched, use a quality plastic
polishing compound after
washing.
After normal useRemove dirt with warm water, a mild
detergent, and a soft, clean sponge,
and then rinse thoroughly with clean
water. Use a toothbrush or bottlebrush
for hard-to-reach areas. Stubborn dirt
and insects will come off more easily if
the area is covered with a wet cloth for
a few minutes before cleaning.
After riding in the rain, near the sea oron salt-sprayed roadsSince sea salt or salt sprayed on roads
during winter are extremely corrosive in
combination with water, carry out the
following steps after each ride in the
rain, near the sea or on salt-sprayed
roads.
TIPSalt sprayed on roads in the winter may
remain well into spring.1. Clean the motorcycle with cold wa-
ter and a mild detergent, after the
engine has cooled down.
NOTICE: Do not use warm water
since it increases the corrosive
action of the salt.
[ECA10791]
2. Apply a corrosion protection spray on all metal, including chrome- and
nickel-plated, surfaces to prevent
corrosion.
After 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 in-
duced discoloring of stainless-
steel exhaust systems can be re-
moved through polishing.)

72. Fill up the fuel tank and add fuel
stabilizer (if available) to prevent
the fuel tank from rusting and the
fuel from deteriorating.
3. Perform the following steps to pro- tect 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 then place
the spark plugs on the cylinder
head so that the electrodes are
grounded. (This will limit spark-
ing during the next step.)
d. Turn the engine over several times with the starter. (This will
coat the cylinder walls with oil.)
WARNING! To prevent dam- age or injury from sparking,
make sure to ground the
spark plug electrodes while
turning the engine over.
[EWA10951]
e. Remove the spark plug caps from the spark plugs, and then
install the spark plugs and the
spark plug caps.
4. Lubricate all control cables and the pivoting points of all levers and
pedals as well as of the side-
stand/centerstand.
5. Check and, if necessary, correct the tire air pressure, and then lift
the motorcycle so that both of its
wheels are off the ground. Alterna-
tively, turn the wheels a little every
month in order to prevent the tires
from becoming degraded in one
spot.
6. Cover the muffler outlet with a plastic bag to prevent moisture
from entering it.
7. Remove the battery and fully charge it. Store it in a cool, dry
place and charge it once a month.
Do not store the battery in an ex-
cessively cold or warm place [less
than 0 °C (30 °F) or more than 30
°C (90 °F)]. For more information
on storing the battery, see page
6-30.
TIPMake any necessary repairs before
storing the motorcycle.
