Throttle OverRide System
If during operation, the carburetor or the throttle ca-
ble should malfunction and will not close fully, take
your thumb off the throttle lever.
The throttle override system immediately cuts off
the ignition.
WARNING

EWB00260
Riding with a malfunction increases the
chance for an accident and injury. Make sure
that the cause of the malfunction is corrected
before restarting the engine or have the ATV in-
spected by a Yamaha dealer.
EBU18323
Speed limiter
Your ATV is equipped with an adjustable speed
limiter. The speed limiter keeps the throttle from
fully opening, even when the throttle lever is
pushed to the maximum.
1. Loosen the locknut.
2. To increase the maximum engine power avail-
able and the maximum speed of the ATV, turn
the adjusting screw in direction (a). To de-
crease the maximum engine power available
and the maximum speed of the ATV, turn the
adjusting screw in direction (b). Do not turn
the adjusting screw out more than 12 mm
(0.47 in) or the throttle cable could be dam-
aged. Always make sure the throttle lever free
play is adjusted to 4.0–6.0 mm (0.16–0.24 in).

expectedly if the parking brake is not ap-
plied. This could cause loss of control or a
collision.

Always be sure you have released the park-
ing brake before you begin to ride. The brake
could overheat if you ride the ATV without re-
leasing the parking brake. You could lose
braking performance which could cause an
accident. You could also wear out the brakes

Fuel
Make sure there is sufficient gasoline in the tank.
WARNING

EWB02521
Gasoline and gasoline vapors are extremely
flammable. To avoid fires and explosions and
to reduce the risk of injury when refueling, fol-
low these instructions.
1. Before refueling, turn off the engine and be
sure that no one is sitting on the vehicle. Nev-
er refuel while smoking, or while in the vicinity
of sparks, open flames, or other sources of ig-nition 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 reach-
es the bottom of the filler tube. Because fuel
expands when it heats up, heat from the en-
gine or the sun can cause fuel to spill out of
the fuel tank.

3. Wipe up any spilled fuel immediately.
NOTICE:
Immediately wipe off spilled fuel
with a clean, dry, soft cloth, since fuel may
deteriorate painted surfaces or plastic
parts.
[ECB00981]

4. Turn the fuel tank cap fully clockwise to make
sure it is securely closed.
WARNING

EWB02531
Gasoline is poisonous and can cause injury or
death. Handle gasoline with care. Never siphon
gasoline by mouth. If you should swallow
some gasoline or inhale a lot of gasoline vapor,
or get some gasoline in your eyes, see your
doctor immediately. If gasoline spills on your
skin, wash with soap and water. If gasoline
spills on your clothing, change your clothes.
NOTICE

ECB00060
Use only unleaded gasoline. The use of leaded
gasoline will cause severe damage to internal
engine parts, such as the piston rings, as well
as to the exhaust system.
Your Yamaha engine has been designed to use
premium unleaded gasoline with a research oc-
tane number of 95 or higher. If knocking (or ping-
ing) occurs, use a gasoline of a different brand.
Use of unleaded fuel will extend spark plug life and
reduce maintenance costs.

buretors while also filtering it.

lows and shown in the illustrations. Recommended fuel:
