push down on the handlebars
several times and check if the
fork rebounds smoothly.

the specified tightening torque.
Tighten the upper nuts first and
then lower ones. When tightened
in this sequence, there should be
a gap formed at the bottom of

Front wheel installation1.Install the speedometer gear unit
housing into the wheel hub.
Make sure the speedometer gear
unit housing is installed with the
projections meshed into the
slots.
2.Lift up the wheel between the
front fork legs and guide the
brake disc between the brake
pads. Make sure there is enough
gap between the brake pads
before inserting the brake disc.
3.Make sure the slot in the
speedometer gear unit fits over
the stopper on the front fork
outer tube.
4.Install the wheel axle and tighten
it to the specified torque.

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. Conse-quently, they have a
shorter service life and can lead to
expensive repair bills.
5.Push the wheel forward and
remove the drive chain.
6.Pull out the wheel axle, then
remove the wheel assembly by
pulling backwards.NOTE:
8Do not depress the brake pedal
when the disc and caliper are
separated.
8You do not have to disassemble
the chain in order to remove or
install the rear wheel.
EAU01136*
Rear wheel installation1.Install the rear wheel and chain.
Guide the brake disc between
the brake pads. Make sure there
is enough gap between the
brake pads before inserting the
brake disc.
2.Make sure the wheel axle is
inserted from the left-hand side
and that the chain adjusting
plates are installed with the
punched side outward.
3.Install the swingarm end bolts.
4.Adjust the drive chain.
5.Tighten the following parts to the
specified torque.
Tightening torque:
Axle nut:
105 Nm (10.5 m
0kg)
Caliper bracket bolt:
48 Nm (4.8 m
0kg)
Swingarm end bolt:
2.5 Nm (0.25 m0kg)

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 roads.Since 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.

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.

Never apply oil or wax on rub-
ber and plastic parts, but treat
them with a suitable care prod-
uct.

Avoid using abrasive polish-
ing compounds as they wear

NOTE:
Consult a Yamaha dealer for advice
on what products to use.
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
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.
