sWARNING
Make sure that the fuel and 2-stro-
ke engine oil tank caps are properly
installed before riding the scooter.
Leaking fuel is a fire hazard.
EAU13212
Fuel
Make sure there is sufficient gasoline
in the tank.
EWA10881
sWARNING
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. 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. 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
sWARNING
Gasoline is poisonous and can cau-
se injury or death. Handle gasoline
with care. Never siphon gasoline by

NOTICE
See page 5-4 for engine break-in
instructions prior to operating the
vehicle for the first time.
1. Turn the key to “ ”, and when
the oil level warning light comes
on, turn it to “ ”.
ECA10240
NOTICE
If the oil level warning light does
not come on, have a Yamaha dealer
check the electrical circuit.
2. Close the throttle completely.3. While applying the front or rear
brake, start the engine by pus-
hing the start switch or by pus-
hing the kickstarter lever down.
NOTICE: For maximum engine
life, never accelerate hard
when the engine is cold!
[ECA11041]
If the engine fails to start by pus-
hing the start switch, release the
switch, wait a few seconds, and
then try again. Each starting
attempt should be as short as
possible to preserve the battery.
Do not crank the engine more
than 5 seconds on any one
attempt. If the engine does not

TIP
If a torque wrench is not available
when installing a spark plug, a good
estimate of the correct torque is
1/4–1/2 turn past finger tight. Howe-
ver, the spark plug should be tighte-
ned to the specified torque as soon
as possible.
EAU20064
Final transmission oil
The final transmission case must be
checked for oil leakage before each
ride. If any leakage is found, have a
Yamaha dealer check and repair the
scooter. In addition, the final trans-
mission oil must be changed as
follows at the intervals specified in the
periodic maintenance and lubrication
chart.
1. Start the engine, warm up the
final transmission oil by riding the
scooter for several minutes, and
then stop the engine.
2. Place the scooter on the centers-
tand.
3. Place an oil pan under the final
transmission case to collect the
used oil.
4. Remove the final transmission oil
filler cap and final transmission
drain bolt to drain the oil from the
final transmission case.

5. Install the final transmission oil
drain bolt, and then tighten it to
the specified torque.
