wise, the engine will misfire, preventing normal op-
eration.
WARNING

EWB00220

Always set the parking brake before starting
the engine. The ATV could start moving un-
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

speed transmission. The shift pedal is located on
the left side of the engine and is used in combina-
tion with the clutch when shifting.

Fold out the kickstarter lever, move it down lightly
with your foot until the gears engage, and thenpush it down smoothly but forcefully. This model is
equipped with a primary kickstarter, allowing the
engine to be started in any gear if the clutch is dis-
engaged. However, shifting the transmission into
the neutral position before starting is recommend-
ed.

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.
EBU18830
Fuel cock
The fuel cock supplies fuel from the tank to the car-
buretors while also filtering it.
The fuel cock lever positions are explained as fol-
lows and shown in the illustrations. Recommended fuel:
PREMIUM UNLEADED GASOLINE ONLY
For Europe: PREMIUM UNLEADED GASO-
LINE ONLY with a research octane number
of 95 or higher.
Fuel tank capacity:
12.0 L (3.17 US gal, 2.64 Imp.gal)
Fuel reserve amount:

Fuel and 2-stroke engine oil mixing
ratio
If Yamalube “R” oil is not available, select an oil
from the following list.
NOTICE

ECB00140
Never mix two types of 2-stroke engine oil in
the same batch. Always use the same type of
oil to ensure maximum engine performance.
EBU19580
Transmission oil
Make sure that the transmission oil is at the speci-
fied level. Add oil as necessary. (See page 8-10.)
EBU19631
Coolant
Make sure that the coolant is at the specified level.
Add coolant as necessary. (See page 8-13.)
TIP

The coolant level must be checked on a cold en-
gine since the level varies with engine tempera-
ture.
EBU19711
Front and rear brakes
Brake lever and brake pedal

Check that there is no free play in the brake le-
ver. If there is free play, have a Yamaha dealer
check the brake system.

Check for correct brake pedal height. (See
page 8-38.) If the pedal height is incorrect, have
a Yamaha dealer adjust it.

Check the operation of the lever and pedal. They
should move smoothly and there should be a
firm feeling when the brakes are applied. If not,
have a Yamaha dealer check the brake system.
Brake fluid level
Check the brake fluid level. Add fluid if necessary. Recommended 2-stroke engine oil:
Yamalube “R” (Yamalube Racing 2-cycle oil)
Mixing ratio:

6. Completely close the throttle lever and start
the engine by kicking the kickstarter.
7. If the engine is started with the starter (choke)
in position (1), the starter (choke) should be
returned to position (2) to warm up the engine.

in position (2), keep the starter (choke) in this
position to warm up the engine.
8. Continue warming up the engine until it idlessmoothly, then return the starter (choke) to
position (3) before riding.TIP

The engine is warm when it responds quickly to
the throttle with the starter (choke) turned off.

When the parking brake is applied, engine
speed is limited to 2300 r/min. Make sure the
parking brake is released before moving the
throttle lever; otherwise, the engine will misfire,
preventing normal operation.NOTICE

ECB00163
For maximum engine life, never accelerate
hard when the engine is cold!
EBU20291
Starting a warm engine
Follow the same procedure as for starting a cold
engine, with the exception that the starter (choke)
is not required when the engine is warm. Instead,
start the engine with the throttle slightly open.
