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 that there is sufficient fuel in
the tank. When refueling, be sure to in-
sert the pump nozzle into the fuel tank
filler hole and to fill the tank to the bot-
tom of the filler tube as shown.
WARNING
EWA10880
Do not overfill the fuel tank, oth-
erwise it may overflow when the
fuel warms up and expands.
Avoid spilling fuel on the hot en-
gine.
CAUTION:
ECA10070
Immediately wipe off spilled fuel
with a clean, dry, soft cloth, since
fuel may deteriorate painted surfac-
es or plastic parts.
EAU41960
CAUTION:
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 of91 or higher. If knocking (or pinging) oc-
curs, use a gasoline of a different brand
or premium unleaded fuel. Use of un-
leaded fuel will extend spark plug life
and reduce maintenance costs.

tioned straight up when checking the
2-stroke engine oil level. A slight tilt to
the side can result in a false reading.
1. Remove the seat. (See page 3-6.)
2. Remove the 2-stroke engine oiltank cap and add the recommend-
ed oil.

Fuel cock
The fuel cock supplies fuel from the
tank to the carburetor while filtering it al-
so.
The fuel cock has three positions:
OFF
With the lever in this position, fuel will
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.
RES
This indicates reserve. If you run out of
fuel while riding, move the lever to this
position. Fill the tank at the first oppor-
tunity. Be sure to set the lever back to
“ON” after refueling!

Shock absorber
WARNING
EWA10220
This shock absorber contains highly
pressurized nitrogen gas. For prop-
er handling, read and understand
the following information before
handling the shock absorber. The
manufacturer cannot be held re-
sponsible for property damage or
personal injury that may result from
improper handling.
Do not tamper with or attempt to
open the gas cylinder.
Do not subject the shock ab-
sorber to an open flame or other
high heat sources, otherwise it
may explode due to excessive
gas pressure.
Do not deform or damage the
gas cylinder in any way, as this
will result in poor damping per-
formance.
Always have a Yamaha dealer
service the shock absorber.

PRE-OPERATION CHECKS
EAU15593
The condition of a vehicle is the owner’s responsibility. Vital components can start to deteriorate quickly and unexpectedly,
even if the vehicle remains unused (for example, as a result of exposure to the elements). Any damage, fluid leakage or loss
of tire air pressure could have serious consequences. Therefore, it is very important, in addition to a thorough visual inspec-
tion, to check the following points before each ride.
NOTE:
Pre-operation checks should be made each time the vehicle is used. Such an inspection can be accomplished in a very short
time; and the added safety it assures is more than worth the time involved.
WARNING
EWA11150
If any item in the Pre-operation check list is not working properly, have it inspected and repaired before operating
the vehicle.
