TIPThe fuel tank cap cannot be closed un-
less the key is in the lock. In addition,
the key cannot be removed if the cap is
not properly closed and locked.
WARNING
EWA11091
Make sure that the fuel tank cap is
properly closed after filling fuel.
Leaking fuel is a fire hazard.
EAU13221
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. When
refueling, be sure to insert the
pump nozzle into the fuel tank filler
hole. 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 in
your eyes, see your doctor immedi-1. Fuel tank filler tube

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.

Fuel tank breather/overflow
hose Before operating the motorcycle:
Check the fuel tank breather/over-
flow hose connection.
Check the fuel tank breather/over-
flow hose for cracks or damage,
and replace it if damaged.
Make sure that the end of the fuel
tank breather/overflow hose is not
blocked, and clean it if necessary.
Recommended fuel:
Premium unleaded gasoline only
Fuel tank capacity:
21.0 L (5.55 US gal, 4.62 Imp.gal)

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.

under the seat. (See page 3-15.)
When storing the Owner’s Manual or
other documents in the storage com-

plastic bag so that they will not get wet.
When washing the vehicle, be careful
not to let any water enter the storage
compartment.

Adjusting the shock absorber
assembly
WARNING
EWA10210
Always adjust both shock absorber
assemblies equally, otherwise poor
handling and loss of stability may
result.Each shock absorber assembly is
equipped with a spring preload adjust-
ing ring and rebound and compression
damping force adjusting knobs.
Spring preload
Adjust the spring preload as follows.
1. Loosen the lock screw 1/2 turn
counterclockwise.2. To increase the spring preload and
thereby harden the suspension,
turn the adjusting ring in direction
(a). To decrease the spring pre-
load and thereby soften the sus-
pension, turn the adjusting ring in
direction (b).
Use the special wrench in-
cluded in the owner’s tool kit
to make this adjustment.
The spring preload setting is
determined by measuring dis-
tance A, shown in the illustra-
tion. The longer distance A is,
the higher the spring preload;
the shorter distance A is, the
lower the spring preload. With
each complete turn of the ad-
justing ring, distance A chang-
es by 1.5 mm (0.06 in).
Be sure to turn the adjusting
ring so that the lock screw is
facing outward.

To increase the rebound damping force
and thereby harden the rebound damp-
ing, turn the adjusting knob in direction
(a). To decrease the rebound damping
force and thereby soften the rebound
damping, turn the adjusting knob in di-
rection (b).Compression damping force
To increase the compression damping
force and thereby harden the compres-
sion damping, turn the adjusting knob
in direction (a). To decrease the com-
pression damping force and thereby
soften the compression damping, turn

When checking the fluid level,
make sure that the top of the brake
or clutch fluid reservoir is level.
Use only the recommended quality
brake fluid, otherwise the rubber
seals may deteriorate, causing
leakage and poor braking or clutch
performance.
Refill with the same type of brake
fluid. Mixing fluids may result in a
harmful chemical reaction and
lead to poor braking or clutch per-
formance.
The brake or clutch fluid reservoir
diaphragm will lose its shape from
the negative pressure if the fluid
level goes down too far. Be sure to
return the diaphragm to its original
shape before installing it into the
brake or clutch fluid reservoir.
Be careful that water does not en-
ter the brake or clutch fluid reser-
voir when refilling. Water willsignificantly lower the boiling point
of the fluid and may result in vapor
lock.
Brake fluid may deteriorate paint-
ed surfaces or plastic parts. Al-
ways clean up spilled fluid
immediately.
As the brake pads wear, it is nor-
mal for the brake fluid level to grad-
ually go down. However, if the
brake fluid level goes down sud-
denly, have a Yamaha dealer
check the cause.
EAU22751
Changing the brake and
clutch fluids Have a Yamaha dealer change the
brake and clutch fluids at the intervals
specified in the TIP after the periodic
maintenance and lubrication chart. In
addition, have the oil seals of the brake
and clutch master cylinders and cali-
pers as well as the brake and clutch
hoses replaced at the intervals listed
below or whenever they are damaged
or leaking.
Oil seals: Replace every two
years.
Brake and clutch hoses: Replace
every four years.

id:

Drive chain slack The drive chain slack should be
checked before each ride and adjusted
if necessary.
EAU22793
To check the drive chain slack
1. Place the motorcycle on the cen-
terstand.
2. Shift the transmission into the neu-
tral position.
3. Spin the rear wheel several times
to locate the tightest portion of the
drive chain.
4. Measure the drive chain slack as
shown.5. If the drive chain slack is incorrect,
adjust it as follows.
EAU49311
To adjust the drive chain slack
1. Take the motorcycle off the center-
stand, and then put the sidestand
down.
2. Loosen the axle nut and the lock-
nut on each side of the swingarm.
3. Place the motorcycle on the cen-
terstand.
4. To tighten the drive chain, turn the
drive chain slack adjusting bolt on
each side of the swingarm in direc-
tion (a). To loosen the drive chain,
turn the adjusting bolt on each side
of the swingarm in direction (b),
and then push the rear wheel for-
ward. NOTICE: Improper drive
chain slack will overload the en-
gine as well as other vital parts
of the motorcycle and can lead
to chain slippage or breakage.To prevent this from occurring,
keep the drive chain slack with-
in the specified limits.

TIPUsing the alignment marks on each
side of the swingarm, make sure that
both drive chain pullers are in the same
