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.

Engine oil and oil filter
element The engine oil level should be checked
before each ride. In addition, the oil
must be changed and the oil filter ele-
ment replaced at the intervals specified
in the periodic maintenance and lubri-
cation chart.
To check the engine oil level
1. Place the motorcycle on a level
surface and hold it in an upright
position.NOTE:_ Make sure that the motorcycle is posi-
tioned straight up when checking the oil
level. 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.
NOTE:_ The 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. Tightening torque:

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 motorcycle. In
addition, the final gear oil level must be
checked and the oil changed as follows
at the intervals specified in the periodic
maintenance and lubrication chart.
EW000066
WARNING
_
Make sure that no foreign mate-
rial enters the final gear case.
Make sure that no oil gets on
the tire or wheel.
_To check the final gear oil level
1. Place the motorcycle on a level
surface and hold it in an upright
position.
NOTE:_
The final gear oil level must be
checked on a cold engine.
Make sure that the motorcycle is
positioned straight up when
checking the oil level. A slight tilt to
the side can result in a false read-
ing.
_2. Remove the oil filler bolt, and then
check the oil level in the final gear
case.
NOTE:_ The oil level should be at the brim of
the filler 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.
To change the final gear oil
1. Place an oil pan under the final
gear case to collect the used oil.
2. Remove the oil filler bolt and drain
bolt to drain the oil from the final
gear case.
3. Install the final gear oil drain bolt,
and then tighten it to the specified
torque.
4. Add the recommended final gear
oil to the brim of the filler hole.

Checking the brake fluid level Insufficient brake fluid may allow air to
enter the brake system, possibly caus-
ing it to become ineffective.
Before riding, check that the brake fluid
is above the minimum level mark and
replenish if necessary. A low brake flu-
id level may indicate worn brake pads
and/or brake system leakage. If the
brake level is low, be sure to check the
brake pads for wear and the brake sys-
tem for leakage.Observe these precautions:
When checking the fluid level,
make sure that the top of the brake
fluid reservoir is level.
Use only the recommended quali-
ty brake fluid, otherwise the rubber
seals may deteriorate, causing
leakage and poor braking perfor-
mance.
Refill with the same type of brake
fluid. Mixing fluids may result in a
harmful chemical reaction and
lead to poor braking performance.
Be careful that water does not en-
ter the brake fluid reservoir when
refilling. Water will significantly
lower the boiling point of the fluid
and may result in vapor lock.
Brake fluid may deteriorate paint-
ed surfaces or plastic parts. Al-
ways clean up spilled fluid
immediately.
As the brake pads wear, it is nor-
mal for the brake fluid level to
gradually go down. However, if the
brake fluid level goes down sud-
denly, have a Yamaha dealer
check the cause.

CAUTION:Be sure to use motor oils that do not contain anti-friction
modifiers. Passenger car motor oils (often labeled
“ENERGY CONSERVING II”) contain anti-friction additives
which will cause clutch and/or starter clutch slippage, result-
