TIPIf 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.

Engine oil and oil filter car-
tridge The engine oil level should be checked
before each ride. In addition, the oil
must be changed and the oil filter car-
tridge replaced at the intervals speci-
fied in the periodic maintenance and
lubrication chart.
To check the engine oil level
1. Place the vehicle on the center-
stand. A slight tilt to the side can
result in a false reading.
2. Start the engine, warm it up for
several minutes, and then turn it
off.
3. Wait a few minutes until the oil set-
tles, and then check the oil level
through the check window located
at the bottom-left side of the crank-
case.TIPThe engine oil should be between theminimum and maximum level marks.4. If the engine oil is below the mini-
mum level mark, add sufficient oil
of the recommended type to raise
it to the correct level.
To change the engine oil (with or
without oil filter cartridge replace-
ment)
1. Place the vehicle on a level sur-
face.
2. Start the engine, warm it up for
several minutes, and then turn it
off.
3. Place an oil pan under the engine
to collect the used oil.

then tighten it to the specified
torque.
TIPCheck the washer for damage and re-place it if necessary.
9. Refill with the specified amount of
the recommended engine oil, and
then install and tighten the oil filler
cap.
TIPBe sure to wipe off spilled oil on any
parts after the engine and exhaust sys-tem have cooled down.NOTICE
ECA11620
In order to prevent clutch slip-
page (since the engine oil also
lubricates the clutch), do not
mix any chemical additives. Do
not use oils with a diesel speci-
fication of “CD” or oils of a high-
er quality than specified. In
addition, do not use oils labeled
“ENERGY CONSERVING II” or
higher.
Make sure that no foreign mate-rial enters the crankcase.10. 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.
TIPAfter the engine is started, the engine
oil level warning light should go off if theoil level is sufficient.NOTICE

If the oil level warning light flickers
or remains on, immediately turn the
engine off and have a Yamaha dealercheck the vehicle.

Final gear oil The final gear case must be checked
for oil leakage before each ride. If any
leakage is found, have a Yamaha deal-
er check and repair the vehicle. In addi-
tion, the final gear oil must be changed
as follows at the intervals specified in
the periodic maintenance and lubrica-
tion chart.
WARNING
EWA10370
Make sure that no foreign mate-
rial enters the final gear case.
Make sure that no oil gets on thetire or wheel.
To check the final gear oil level
1. Place the vehicle on the center-
stand.
TIP
The final gear oil level must be
checked on a cold engine.
Make sure that the vehicle is posi-
tioned straight up when checking
the oil level. A slight tilt to the sidecan result in a false reading.2. Remove the final gear oil filler bolt,
and then check the oil level in the
final gear case.
TIPThe oil level should be at the brim of thefiller hole.
3. If the oil is below the brim of the fill-
er hole, add sufficient oil of the rec-
ommended type to raise it to the
correct level.

specified in the periodic maintenance
and lubrication chart.

To check the coolant level
1. Place the vehicle on the center-

the coolant level. A slight tilt to theside can result in a false reading.
2. Check the coolant level in the cool-
ant reservoir.

YCC-S clutch This model is equipped with a hydraulic
clutch, therefore, it is necessary to
check the YCC-S clutch fluid level and
check the hydraulic system for leakage
before each ride. If the YCC-S clutch
plates wear out, shifting becomes
rough or clutch slippage will occur,
causing poor acceleration. If any of the
above occurs, have a Yamaha dealer
check the YCC-S clutch.
