Oil change indicator
This indicator changes from green to
red every 2000 km (1200 mi) to indicate
that the engine oil should be changed.
After changing the engine oil, push the
oil change indicator reset switch in with
the main switch key.
If the engine oil is changed before the
2000 km (1200 mi) interval, the indica-
tor must be reset after the oil change for
the next periodic oil change to be indi-
cated at the correct time.
NOTE:After resetting the oil change indicator
reset switch, the indicator changesfrom red to green.CAUTION:
ECA10280
After 1000 km (600 mi) of operation,the engine oil must be changed.

when an electrical circuit monitoring the
engine is defective. When this occurs,
have a Yamaha dealer check the self-
diagnosis system.
The electrical circuit of the warning light
can be checked by turning the key to
“ON”. If the warning light does not come
on for a few seconds, then go off, have
a Yamaha dealer check the electrical
circuit.

62. Clean the surface of the spark plug
gasket and its mating surface, and
then wipe off any grime from the
spark plug threads.
3. Install the spark plug with the
spark plug wrench, and then tight-
en it to the specified torque.
NOTE: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. However, the spark
plug should be tightened to the speci-fied torque as soon as possible.
4. Install the spark plug cap.
5. Install the panel.
EAU45480
Engine oil The engine oil level should be checked
before each ride. In addition, the oil
must be changed at the intervals spec-
ified in the periodic maintenance and
lubrication chart.
The engine oil must also be changed at
the initial 1000 km (600 mi) and when
the oil change indicator color changes
from green to red. The oil change indi-
cator must be reset after the initial 1000
km (600 mi). (See page 3-2 for reset
procedures.)
To check the engine oil level
1. Place the vehicle on the center-
stand.NOTE:Make sure that the vehicle is positioned
straight up when checking the oil level.
A slight tilt to the side can result in afalse reading.
2. Start the engine, warm it up for
several minutes, and then turn it
off.

CAUTION:
ECA11670
Do not use oils with a diesel
specification of “CD” or oils of a
higher quality than specified. In
addition, do not use oils labeled
“ENERGY CONSERVING II” or
higher.
Be sure no foreign material en-ters the crankcase.
7. Start the engine, and then let it idle
for several minutes while checking
it for oil leakage. If oil is leaking, im-
mediately turn the engine off and
check for the cause.8. Turn the engine off, and then
check the oil level and correct it if
necessary.
9. Reset the oil change indicator.
(See page 3-2 for reset proce-
dures.)
NOTE:If the engine oil is changed before the
oil change indicator color changes from
green to red (i.e. before the periodic oil
change interval has been reached), the
oil change indicator must be reset after
the oil change for the next periodic oil
change to be indicated at the correcttime.
EAU20063
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 final transmission
drain bolt to drain the oil from the fi-
nal transmission case.
