Power reduction plate
Your motorcycle was delivered with a
power reduction plate. Yamaha recom-
mends that all beginning riders start off
with the power reduction plate installed
to limit the amount of power available
while they learn.
Parents should decide when to adjust
the motorcycle for more power as their
youngster’s riding skills improve. Once
the rider can operate with skill at the top
speed with the power reduction plate
installed, the power reduction plate can
be removed. (See page 6-6.)

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 inyour 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.
EAU41960
NOTICE

ECA15590
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 de-
signed to use regular unleaded gaso-
line with a research octane number of
91 or higher. If knocking (or pinging) oc-

curs, use a gasoline of a different brand

and reduce maintenance costs.

Fuel tank breather hose
Before operating the motorcycle:

Check the fuel tank breather hose
connection.

Check the fuel tank breather hose
for cracks or damage, and replace
it if damaged.

Make sure that the fuel tank

tion, add a sufficient amount of the rec-
ommended 2-stroke engine oil as
follows.
TIP

Make sure that the motorcycle is posi-
tioned straight up when checking the
2-stroke engine oil level. A slight tilt to

tank to the carburetor while filtering it al-
so.
The fuel cock has three positions:

not flow. Always return the lever to this
position when the engine is not running.
ON
With the lever in this position, fuel flows
to the carburetor. Normal riding is done
with the lever in this position.

Shock absorber assembly
WARNING

EWA10221
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.
