NOTE:
If the engine oil is changed before the
oil change indicator light comes on
(i.e. before the periodic oil change
interval has been reached), the indi-
cator light must be reset after the oil
change for the next periodic oil
change to be indicated at the correct
time. To reset the oil change indicator
light before the periodic oil change
interval has been reached, follow the
above procedure, but note that the
indicator light will come on for 1.4
seconds after releasing the reset but-
ton, otherwise repeat the procedure.

Final gear oilThe final gear 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 gear oil
must be changed as follows 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.NOTE:
Make sure that the scooter is posi-
tioned straight up when checking the
oil level. A slight tilt to the side can
result in a false reading.3.Place an oil pan under the final
gear case to collect the used oil.

CoolantThe coolant reservoir is located
under the battery cover. (See page
6-31 for battery cover removal proce-
dures.)
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.

EC000080
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.

Cleaning the air filter element
1.Place the scooter on the center-
stand.
2.Remove the air filter case cover
by removing the screws.
3.Pull the sponge material out
along with the mesh sheet, clean
it with solvent, and then squeeze

Air filter and V-belt case air
filter elementsThe air filter and V-belt case air filter
elements should be cleaned at the
intervals specified in the periodic

Clean both filter elements more fre-
quently if you are riding in unusually
wet or dusty areas.
EC000092
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(s) and/or cylinder(s)
may become excessively
worn.

Changing the brake fluidHave a Yamaha dealer change the
brake fluid at the intervals specified in
the periodic maintenance and lubrica-
tion chart. In addition, have the oil
seals of the master cylinder and
caliper as well as the brake hoses
replaced at the intervals listed below
or whenever they are damaged or
leaking.
8Oil seals: Replace every two
years.
8Brake hoses: Replace every four
years.

Checking and lubricating the
cablesThe operation of all control cables
and the condition of the cables
should be checked before each ride,
and the cables and cable ends
should be lubricated if necessary. If
a cable is damaged or does not move
smoothly, have a Yamaha dealer
check or replace it.
EW000112
wDamage to the outer sheath may
interfere with proper cable opera-
tion and will cause the inner cable
to rust. Replace a damaged cable
as soon as possible to prevent
unsafe conditions.
Recommended lubricant:
Engine oil
EAU03118
Lubricating the front and
rear brake leversThe pivoting points of the front and
rear brake levers must be lubricated
at the intervals specified in the peri-
odic maintenance and lubrication
chart.
Recommended lubricant:

Checking the steeringWorn or loose steering bearings may
cause danger. Therefore, the opera-
tion of the steering must be checked
as follows at the intervals specified in
the periodic maintenance and lubrica-
tion chart.
1.Place a stand under the engine
to raise the front wheel off the
ground.
EW000115
wSecurely support the scooter so
that there is no danger of it falling
over.
2.Hold the lower ends of the front
fork legs and try to move them
forward and backward. If any
free play can be felt, have a
Yamaha dealer check or repair
the steering.
