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.

CoolantCoolantThe coolant reservoir is located
under the battery cover. (See page
6-34 for battery cover removal and
installation procedures.)
To check the coolant level
1. Place the scooter on a level sur-
face and hold it in an upright
position.NOTE:
8The coolant level must be
checked on a cold engine since
the level varies with engine tem-
perature.
8Make sure that the scooter is
positioned straight up when
checking the coolant level. A
slight tilt to the side can result in
a false reading.
2. Check the coolant level in the
coolant reservoir.NOTE:
The coolant should be between the
minimum and maximum level marks.

maximum level mark, and then
install the reservoir cap.

cC8If coolant is not available, use
distilled water or soft tap water
instead. Do not use hard water
or salt water since it is harmful
to the engine.
8If water has been used instead
of coolant, replace it with
coolant as soon as possible,
otherwise the engine may not
be sufficiently cooled and the
cooling system will not be pro-
tected against frost and corro-
sion.
8If water has been added to the
coolant, have a Yamaha dealer
check the antifreeze content of
the coolant as soon as possi-
ble, otherwise the effective-
ness of the coolant will be
reduced.
NOTE:
The radiator fan is automatically
switched on or off according to the
coolant temperature in the radiator. If
the engine overheats, see page 6-44
for further instructions.

filter elementsAir filter and V-belt case air filter elements, cleaningThe air filter and V-belt case air filter
elements should be cleaned at the
intervals specified in the periodic
maintenance and lubrication chart.
Clean both filter elements more fre-
quently if you are riding in unusually
wet or dusty areas.

cC8Make sure that each filter ele-
ment is properly seated in its
case.
8The engine should never be
operated without the filter ele-
ments installed, otherwise the
piston and/or cylinder may
become excessively worn.

TiresTiresTo maximize the performance, dura-
bility, and safe operation of your
scooter, note the following points
regarding the specified tires.
Tire air pressure
The tire air pressure should be
checked and, if necessary, adjusted
before each ride.
EW000082
w8The tire air pressure must be
checked and adjusted on cold
tires (i.e., when the tempera-
ture of the tires equals the
ambient temperature).
8The tire air pressure must be
adjusted in accordance with
the riding speed and with the
total weight of rider, passen-
ger, cargo, and accessories
approved for this model.

wBecause loading has an enormous
impact on the handling, braking,
performance and safety character-
istics of your scooter, you should
keep the following precautions in
mind.
8NEVER OVERLOAD THE
SCOOTER! Operation of an
overloaded scooter may result
in tire damage, loss of control,
or severe injury. Make sure
that the total weight of rider,
cargo, and accessories does
not exceed the specified maxi-
mum load for the vehicle.
8Do not carry along loosely
packed items, which can shift
during a ride.
8Securely pack the heaviest
items close to the center of the
scooter and distribute the
weight evenly on both sides.Tire inspection
The tires must be checked before
each ride. If the center tread depth
reaches the specified limit, if the tire
has a nail or glass fragments in it, or
if the sidewall is cracked, have a
Yamaha dealer replace the tire imme-
diately.

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.
