FuelMake sure there is sufficient gasoline in
the tank.
WARNING
EWA10882
Gasoline and gasoline vapors are
extremely flammable. To avoid fires
and explosions and to reduce the
risk of injury when refueling, followthese 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.
[ECA10072]
4. Be sure to securely close the fuel tank cap.
WARNING
EWA15152
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-
ately. If gasoline spills on your skin,
wash with soap and water. If gaso-
line spills on your clothing, change
your clothes.
EAU75320
NOTICE
ECA11401
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.

TIP
This mark identifies the recom-
mended fuel for this vehicle as
specified by European regulation
(EN228).

Check that gasoline nozzle has thesame identifier when fueling.
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 different
brand. Use of unleaded fuel will extend
spark plug life and reduce maintenance
costs.
Gasohol
There are two types of gasohol: gaso- hol containing ethanol and that contain-
ing methanol. Gasohol containing
ethanol can be used if the ethanol con-
tent does not exceed 10% (E10). Gas-
ohol containing methanol is not
recommended by Yamaha because it
can cause damage to the fuel system
or vehicle performance problems.
EAU80200
Fuel tank overflow hoseBefore operating the vehicle:
Check the fuel tank overflow hose
connection.

Check the fuel tank overflow hose
for cracks or damage, and replace
it if necessary.

Make sure that the end of the fuel
tank overflow hose is not blocked,
and clean it if necessary.

Make sure that the end of the fuel
tank overflow hose is positioned as
shown.

Catalytic converterThis model is equipped with a catalytic
converter in the exhaust system.
WARNING
EWA10863
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 ofheat.
NOTICE
ECA10702
Use only unleaded gasoline. The use
of leaded gasoline will cause unre- pairable damage to the catalytic
converter.

Document storageA document storage space is located
under panel C. (See page 7-9.)
When storing the owner’s manual or
vehicle registration and insurance doc-
uments in the document storage space,
be sure to wrap them in a plastic bag so
that they will not get wet. When wash-
ing the vehicle, avoid letting water enter
the document storage space.NOTICE

Adjusting the front forkThis model is equipped with adjustable
suspension. The spring preload, re-
bound damping force, and compres-
sion damping force of each leg can be
adjusted.
WARNING
EWA10181
Always adjust both fork legs equal-
ly, otherwise poor handling and lossof stability may result.NOTICE


Use extra care to avoid scratch-
ing the gold-anodized finish
when making suspension ad-
justments.

To avoid damaging the suspen-
sion’s internal mechanisms, do
not attempt to turn beyond themaximum or minimum settings.
Spring preload
To increase the spring preload and
thereby harden the suspension, turn
the adjusting nut on each fork in direc-
tion (a). To decrease the spring preload and thereby soften the suspension,
turn the adjusting nut on each fork in di-
rection (b).

Adjusting th e shock absorber
assemblyThis model is equipped with adjustable
suspension. The spring preload, re-
bound damping force, fast compres-
sion damping force, and slow
compression damping force can be ad-
justed.NOTICE
ECA10102
To avoid damaging the mechanism,
do not attempt to turn beyond themaximum or minimum settings.
Spring preload
1. Loosen the locknut.
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).
The spring preload setting is deter-
mined by measuring distance A.
The longer distance A is, the high-
er the spring preload; the shorter distance A is, the lower the spring
preload.

Use the special wrench includ-
ed in the tool kit to make the ad-
justment.
3. Tighten the locknut to the specifiedtorque. NOTICE: Always tighten
the locknut against the adjust-
ing ring, and then tighten the
locknut to the specified
torque.

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.

EXUP systemThis model is equipped with Yamaha’s
EXUP (EXhaust Ultimate Power valve)
system. This system boosts engine
power by means of a valve that controls
exhaust flow within the exhaust cham-
ber.NOTICE
ECA15611
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.
