Fuel tank cap
To remove the fuel tank cap
1. Insert the key into the lock and turn
it counterclockwise as shown.
2. Turn the fuel tank cap counter-
clockwise and pull it off.
To install the fuel tank cap
1. Insert the fuel tank cap into the
tank opening with the key inserted
in the lock, and then turn the cap
clockwise.
2. Turn the key clockwise, and then
remove it.
TIP

The fuel tank cap cannot be installed
unless the key is in the lock. In addition,
the key cannot be removed if the cap is
not properly installed and locked.
WARNING

EWA10121
Make sure that the fuel tank cap is
properly closed and locked before
riding. Leaking fuel is a fire hazard.
EAU13212
Fuel
Make sure there is sufficient gasoline in
the tank.
WARNING

EWA10881
Gasoline and gasoline vapors are
extremely flammable. To avoid fires
and explosions and to reduce the
risk of injury when refueling, follow
these instructions.
1. Before refueling, turn off the en-
gine and be sure that no one is sit-
ting on the vehicle. Never refuel
while smoking, or while in the vi-
cinity of sparks, open flames, or
other sources of ignition such as
the pilot lights of water heaters and
clothes dryers.
2. Do not overfill the fuel tank. Stop
filling when the fuel reaches the
bottom of the filler tube. Because
fuel expands when it heats up,
heat from the engine or the sun
can cause fuel to spill out of the
fuel tank.

NOTICE:
Immediately wipe
off spilled fuel with a clean, dry,
soft cloth, since fuel may deteri-
orate painted surfaces or plastic
parts.

4. Be sure to securely close the fuel
tank cap.
WARNING

EWA15151
Gasoline is poisonous and can
cause injury or death. Handle gaso-
line with care. Never siphon gaso-
line by mouth. If you should swallow
some gasoline or inhale a lot of gas-
oline vapor, or get some gasoline inyour eyes, see your doctor immedi-
ately. If gasoline spills on your skin,
wash with soap and water. If gaso-
line spills on your clothing, change
your clothes.
EAU13390
NOTICE

ECA11400
Use only unleaded gasoline. The use
of leaded gasoline will cause severe
damage to internal engine parts,
such as the valves and piston rings,
as well as to the exhaust system.
Your Yamaha engine has been de-
signed to use premium unleaded gaso-
line with a research octane number of
95 or higher. If knocking (or pinging) oc-
curs, use a gasoline of a differentbrand. Use of unleaded fuel will extend
spark plug life and reduce maintenance
costs.

Catalytic converter
This model is equipped with a catalytic
converter in the exhaust system.
WARNING

EWA10862
The exhaust system is hot after op-
eration. To prevent a fire hazard or
burns:

Do not park the vehicle near
possible fire hazards such as
grass or other materials that
easily burn.

Park the vehicle in a place
where pedestrians or children
are not likely to touch the hot
exhaust system.

Make sure that the exhaust sys-
tem has cooled down before do-
ing any maintenance work.

Do not allow the engine to idle
more than a few minutes. Long
idling can cause a build-up of
heat.
NOTICE

ECA10701
Use only unleaded gasoline. The use
of leaded gasoline will cause unre-pairable damage to the catalytic
converter.

helmet attached to the helmet hold-
er, since the helmet may hit objects,
causing loss of control and possibly
an accident.

Adjusting the front fork
WARNING

EWA10180
Always adjust both fork legs equal-
ly, otherwise poor handling and loss
of stability may result.
This front fork is equipped with rebound
damping force adjusting screws and
compression damping force adjusting
screws.
NOTICE

ECA10101
To avoid damaging the mechanism,
do not attempt to turn beyond the
maximum or minimum settings.

To increase the rebound damping force
and thereby harden the rebound damp-
ing, turn the adjusting screw on each
fork leg in direction (a). To decrease the
rebound damping force and thereby
soften the rebound damping, turn the
adjusting screw on each fork leg in di-
rection (b).
Compression damping force
1. Remove the rubber cap by pulling
it out of the front fork leg.
2. To increase the compression
damping force and thereby harden
the compression damping, turn the
adjusting screw on each fork leg in
direction (a). To decrease the
compression damping force and
thereby soften the compression
damping, turn the adjusting screw
on each fork leg in direction (b).3. Install the rubber cap.
TIP

Although the total number of clicks of a
damping force adjusting mechanism
may not exactly match the above spec-
ifications due to small differences in
production, the actual number of clicks

it would be advisable to check the num-

Front fork bleeding
WARNING

EWA10200
Always bleed both fork legs, other-
wise poor handling and loss of sta-
bility may result.
When riding in extremely rough condi-
tions, the air temperature and pressure
in the front fork will rise. This will in-
crease the spring preload and harden
the front suspension. If this occurs,
bleed the front fork as follows.
1. Elevate the front wheel by placing
a suitable stand under the engine.
TIP

When bleeding the front fork, thereshould be no weight on the front end of
the vehicle.
2. Remove the bleed screws and al-
low all of the air to escape from
each fork leg.
3. Install the bleed screws.

Adjusting the shock absorber
assembly
This shock absorber assembly is
equipped with a spring preload adjust-
ing ring, a rebound damping force ad-
justing dial and a compression
damping force adjusting screw.
NOTICE

ECA10101
To avoid damaging the mechanism,
do not attempt to turn beyond the
maximum or minimum settings.
Spring preload
Spring preload adjustment should be
made by a Yamaha dealer, since this
service requires special tools and tech-
nical skills. The specified settings are
listed below.
The spring preload setting is deter-
mined by measuring distance A, shown
in the illustration. The shorter the dis-
tance A is, the higher the spring pre-
load; the longer distance A is, the lower
the spring preload.
Rebound damping force
To increase the rebound damping force
and thereby harden the rebound damp-
ing, turn the adjusting dial in direction
(a). To decrease the rebound damping
force and thereby soften the rebound
damping, turn the adjusting dial in di-
rection (b).
Compression damping force
To increase the compression damping
force and thereby harden the compres-
sion damping, turn the adjusting screw
in direction (a). To decrease the com-
pression damping force and thereby
soften the compression damping, turn

TIP

To obtain a precise adjustment, it is ad-
visable to check the actual total number
of clicks or turns of each damping force
adjusting mechanism. This adjustment
range may not exactly match the spec-ifications listed due to small differences
in production.
WARNING

EWA10221
This shock absorber assembly con-
tains highly pressurized nitrogen
gas. Read and understand the fol-
lowing information before handling
the shock absorber assembly.

Do not tamper with or attempt to
open the cylinder assembly.

Do not subject the shock ab-
sorber assembly to an open
flame or other high heat source.
This may cause the unit to ex-
plode due to excessive gas
pressure.

Do not deform or damage the
cylinder in any way. Cylinder
damage will result in poor
damping performance.

Do not dispose of a damaged or
worn-out shock absorber as-
sembly yourself. Take the shock
absorber assembly to a Yamaha
dealer for any service.
EAU41940
EXUP system
This model is equipped with Yamaha’s
EXUP (EXhaust Ultimate Power valve)
system. This system boosts engine
power by means of a valve that regu-
lates the diameter of the exhaust pipe.
The EXUP system valve is constantly
adjusted in accordance with the engine
speed by a computer-controlled servo-
motor.
NOTICE

ECA15610
The EXUP system has been set and
extensively tested at the Yamaha
factory. Changing these settings
without sufficient technical knowl-
edge may result in poor perfor-
mance of or damage to the engine.
