1. Insert the fuel tank cap into the
tank opening with the key inserted
in the lock and with the mark on the
cap aligned with the mark on the
fuel tank.
2. Turn the key counterclockwise to
the original position, and then re-
move it.
3. Return the backrest to the original
position.
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

EWA10131
Make sure that the fuel tank cap is
properly installed 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.

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

[ECA10071]

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.
EAU43421
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 converters
This vehicle is equipped with catalytic
converters 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.

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 spring
preload adjusting bolts, rebound damp-
ing force adjusting knobs and compres-
sion damping force adjusting screws.
NOTICE

ECA10101
To avoid damaging the mechanism,
do not attempt to turn beyond the
maximum or minimum settings.Spring preload
To increase the spring preload and
thereby harden the suspension, turn
the adjusting bolt on each fork leg in di-
rection (a). To decrease the spring pre-
load and thereby soften the
suspension, turn the adjusting bolt on
each fork leg in direction (b).
Align the appropriate groove on the ad-
justing mechanism with the top of the
front fork cap bolt.

soften the rebound damping, turn the
adjusting knob on each fork leg in direc-
tion (b).
Compression damping force
To increase the compression damping
force and thereby harden the compres-
sion damping, turn the adjusting screw
on each fork leg in direction (a). To de-
crease the compression damping force
and thereby soften the compression
damping, turn the adjusting screw on
each fork leg in direction (b).

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
always represents the entire adjusting
range. To obtain a precise adjustment,
it would be advisable to check the num-
ber of clicks of each damping force ad-
justing mechanism and to modify the
specifications as necessary.
