Oil level warning light “ ”
This warning light comes on when the
key is in the “ ” position or if the oil
level in the 2-stroke engine oil tank is
low during operation. If the warning
light comes on during operation, stop
immediately and fill the oil tank with
Yamalube 2 or equivalent 2-stroke
engine oil of either JASO grade “FC”
or ISO grades “EG-C” or “EG-D”. The
warning light should go off after the 2-
stroke engine oil tank has been refi-
lled.
TIP
If the warning light does not come on
when the key is in the “ ” position
or does not go off after the 2-stroke
engine oil tank has been refilled, have
a Yamaha dealer check the electrical
circuit.

NOTICE
Do not operate the vehicle until you
know that the engine oil level is suf-
ficient.

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
●The air filter needs more frequent service if you are riding in unusually wet or dusty areas.
●Hydraulic brake service
• Regularly check and, if necessary, correct the brake fluid level.
• Every two years change the brake fluid.
• Replace the brake hoses every four years and if cracked or damaged.

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