Leaking fuel is a fire hazard.
EAU13221
Fuel
Make sure there is sufficient gasoline
in the tank.
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 engi-
ne and be sure that no one is sit-
ting on the vehicle. Never refuel
while smoking, or while in the
vicinity 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.
1. Fuel tank filler tube
2. Maximum fuel level
3. Wipe up any spilled fuel imme-
diately. NOTICE: Immediately
wipe off spilled fuel with a cle-
an, dry, soft cloth, since fuel
may deteriorate painted surfa-
ces or plastic parts.
[ECA10071]
4. Be sure to securely close the fuel
tank cap.
EWA15151
Gasoline is poisonous and can cau-
se injury or death. Handle gasoline
with care. Never siphon gasoline by

If gasoline spills on your skin, wash
with soap and water. If gasoline
spills on your clothing, change your
clothes.

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 sys-
tem.
Your Yamaha engine has been desig-
ned to use regular unleaded gasoline
with a research octane number of 91
or higher. If knocking (or pinging)
occurs, use a gasoline of a different
brand or premium unleaded fuel. Use
of unleaded fuel will extend spark plug
life and reduce maintenance costs.
EAU13445
Catalytic converters
This vehicle is equipped with catalytic
converters in the exhaust system.
EWA10862
The exhaust system is hot after
operation. 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
system has cooled down befo-
re doing any maintenance
work.
Do not allow the engine to idle
more than a few minutes. Long
idling can cause a build-up of
heat.
ECA10701
Use only unleaded gasoline. The
use of leaded gasoline will cause
unrepairable damage to the cataly-
tic converter.

Adjusting the shock
absorber assemblies
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 adjus-
ting ring.
ECA10101
To avoid damaging the mechanism,
do not attempt to turn beyond the
maximum or minimum settings.
Adjust the spring preload as follows.
To increase the spring preload and
thereby harden the suspension, turn
the adjusting ring on each shock
absorber assembly in direction (a). To
decrease the spring preload and the-
reby soften the suspension, turn the
adjusting ring on each shock absor-

Sidestand
1. Sidestand switch
The sidestand is located on the left
side of the frame. Raise the sidestand
or lower it with your foot while holding
the vehicle upright.
TIP
The built-in sidestand switch is part of
the ignition circuit cut-off system,
which cuts the ignition in certain
situations. (See page 3-22 for an
explanation of the ignition circuit cut-
off system.)
EWA10240
The vehicle must not be ridden with
the sidestand down, or if the sides-
tand cannot be properly moved up
(or does not stay up), otherwise the
sidestand could contact the ground
and distract the operator, resulting
in a possible loss of control. Yama-
ha’s ignition circuit cut-off system
has been designed to assist the
operator in fulfilling the responsibi-
lity of raising the sidestand before
starting off. Therefore, check this
system regularly as described
below and have a Yamaha dealer
repair it if it does not function pro-
perly.
EAU45051
Ignition circuit cut-off
system
The ignition circuit cut-off system
(comprising the sidestand switch and
brake light switches) has the following
functions.
It prevents starting when the
sidestand is up, but neither brake
is applied.
It prevents starting when either
brake is applied, but the sides-
tand is still down.
It cuts the running engine when
the sidestand is moved down.
Periodically check the operation of
the ignition circuit cut-off system
according to the following procedure.
