Final transmission oilFinal transmission oilThe 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 fol-
lows at the intervals specified in the
periodic maintenance and lubrication
chart.
1. Start the engine, warm it up by
riding the scooter for several
minutes, and then stop the
engine.
2. Place the scooter on the center-
stand.
3. Place an oil pan under the final
transmission case to collect the
used oil.4. Remove the oil filler cap and
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.
6. Add the specified amount of the
recommended final transmission
oil, and then install and tighten
the oil filler cap.

w8Have a Yamaha dealer replace
excessively worn tires.
Besides being illegal, operat-
ing the scooter with exces-
sively worn tires decreases
riding stability and can lead to
loss of control.
8The replacement of all wheel
and brake related parts,
including the tires, should be
left to a Yamaha dealer, who
has the necessary profession-
al knowledge and experience.
NOTE:
The tire tread depth limits may differ
from country to country. Always com-
ply with the local regulations.Tire information

less tires.FRONT

Cast wheelsWheelsTo maximize the performance, dura-
bility, and safe operation of your
scooter, note the following points
regarding the specified wheels.
8The wheel rims should be
checked for cracks, bends or
warpage before each ride. If any
damage is found, have a
Yamaha dealer replace the
wheel. Do not attempt even the
smallest repair to the wheel. A
deformed or cracked wheel must
be replaced.
8The wheel should be balanced
whenever either the tire or wheel
has been changed or replaced.
An unbalanced wheel can result
in poor performance, adverse
handling characteristics, and a
shortened tire life.

cCBe sure to use motor oils that do not contain anti-friction
modifiers. Passenger car motor oils (often labeled “ENERGY
CONSERVING
II”) contain anti-friction additives which will
cause clutch and/or starter clutch slippage, resulting in
reduced component life and poor engine performance.
