TIP
Be sure to wipe off spilled oil on any
parts after the engine and exhaust sys-
tem have cooled down.
NOTICE
ECA11621
 In or der to prevent clutch slip-
pa ge (since the en gine oil also
lu bricates the clutch), do not
mix any chemical additives. Do
not use oils with a diesel speci-
fication of “CD” or oils of a hi gh-
er quality than specifie d. In
a ddition, do not use oils la bele d
“ENERGY CONSERVING II” or
hi gher.
 Make sure that no forei gn mate-
rial enters the crankcase.
8. Start the engine, and then let it idle for several minutes while checking
it for oil leakage. If oil is leaking,
immediately turn the engine off
and check for the cause.
9. Turn the engine off, and then check the oil level and correct it if
necessary.
10. Reset the oil change tripmeter and oil change indicator “OIL”. (See
page 3-6 for reset procedures.)
EAU20067
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 transmis-
sion 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 center- stand.
3. Place an oil pan under the final transmission case to collect the
used oil.
4. Remove the final transmission oil filler cap and its O-ring from the fi-
nal transmission case.
5. Remove the final transmission oil drain bolt and its gasket to drain
the oil from the final transmission
case.
Recommen ded en gine oil:
See page 8-1.
Oil quantity: 0.90 L (0.95 US qt, 0.79 Imp.qt)

6. Install the final transmission oil
drain bolt and its new gasket, and
then tighten the bolt to the speci-
fied torque.
7. Refill with the specified amount of the recommended final transmis-
sion oil. WARNING! Make sure
that no forei gn material enters
the final transmission case.
Make sure that no oil gets on
the tire or wheel.

Coolant
The coolant level should be checked
before each ride. In addition, the cool-
ant must be changed at the intervals
specified in the periodic maintenance
and lubrication chart.
EAUN1090To check the coolant level1. Place the vehicle on the center- stand.
TIP
The coolant level must be
checked on a cold engine since
the level varies with engine tem-
perature.
 Make sure that the vehicle is posi-
tioned straight up when checking
the coolant level. A slight tilt to the
side can result in a false reading.
2. Check the coolant level through
the check window.
TIP
The coolant should be between the
minimum and maximum level marks.
