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
specified torque as soon as possible.NOTICE
ECA10841
Do not use any tools to remove or in-
stall the spark plug cap, otherwise
the i gnition coil coupler may get
d amag ed . The spark plu g cap may
b e difficult to remove because the
ru bber seal on the en d of the cap fits
ti g htly. To remove the spark plu g
cap, simply twist it back an d forth
while pullin g it out; to install it, twist
it back an d forth while pushin g it in.

En gine oil an d oil filter car-
tri dgeThe 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 en gine oil level
1. Place the vehicle on a level sur- face and hold it in an upright posi-
tion. A slight tilt to the side can
result in a false reading.
2. Start the engine and warm it up for ten minutes until the engine oil has
reached a normal temperature of
60 °C (140 °F), and then turn the
engine off.
3. Wait a few minutes until the oil set- tles, and then check the oil level
through the engine oil level check
window located at the bottom-
right side of the crankcase.TIPThe engine oil should be between the
minimum 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 chan ge the en gine oil (with or
without oil filter cartri dge 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.

14. 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.TIPAfter the engine is started, the engine
oil level warning light should go off if
the oil level is sufficient.NOTICE

then check the oil level and cor-
rect it if necessary.

Final g ear oilThe 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 ad-
dition, the final gear oil level must be
checked and the oil changed as fol-
lows at the intervals specified in the
periodic maintenance and lubrication
chart.
WARNING
EWA10371
Make sure that no forei gn mate-
rial enters the final g ear case.
Make sure that no oil gets on
the tire or wheel.To check the final gear oil level
1. Place the vehicle on a level sur- face and hold it in an upright posi-
tion.TIPMake sure that the vehicle is posi-
tioned straight up when checking the
oil level. A slight tilt to the side can re-
sult in a false reading.
2. Remove the final gear oil filler boltand its gasket, and then check the
oil level in the final gear case.TIPThe oil level should be at the brim of
the filler hole.3. If the oil is below the brim of thefiller hole, add sufficient oil of the
recommended type to raise it to
the correct level.
4. Check the gasket for damage, and replace it if necessary.

the final gear case.
3. Install the final gear oil drain bolt and its new gasket, and then tight-
en the bolt to the specified torque. 4. Refill with the recommended final
gear oil to the brim of the filler
hole.
5. Check the oil filler bolt gasket for damage, and replace it if neces-
sary.

CoolantThe coolant level should be checked
before each ride. In addition, the cool-

To check the coolant level1. Place the vehicle on a level sur- face and hold it in an upright posi-
tion.TIPThe 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 in the
coolant reservoir.TIPThe coolant should be between the
minimum and maximum level marks.

TiresTires are the only contact between the
vehicle and the road. Safety in all con-

at the appropriate time with the speci-
fied tires.

centerstand, follow these precautions
when removing the front and rear
wheel or performing other mainte-
nance requiring the motorcycle to
stand upright. Check that the motorcy-
cle is in a stable and level position be-
fore starting any maintenance. A
strong wooden box can be placed un-
der the engine for added stability.
To service the front wheel
1. Stabilize the rear of the motorcy- cle by using a motorcycle stand
or, if an additional motorcycle
stand is not available, by placing a
jack under the frame in front of the
rear wheel.
2. Raise the front wheel off the ground by using a motorcycle
stand.
To service the rear wheel
Raise the rear wheel off the ground by
using a motorcycle stand or, if a motor-
