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 sev-
eral 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.To change the engine oil without oil
filter element replacement
1. Start the engine, warm it up for
several minutes, and then turn it
off.
2. Place an oil pan under the engine
to collect the used oil.
3. Remove the engine oil filler cap
and drain bolt to drain the oil from
the crankcase.4. Install the engine oil drain bolt, and
then tighten it to the specified
torque.
5. Add the specified amount of the
recommended engine oil, and
then install and tighten the oil filler
cap.

6 To check the final gear oil level
1. Place the motorcycle on a level
surface and hold it in an upright
position.
NOTE:@ l
The final gear oil level must be
checked on a cold engine.
l
Make sure that the motorcycle is
positioned straight up when check-
ing the oil level. A slight tilt to the
side can result in a false reading.
@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.
NOTE:@ GL4 is a quality rating. Hypoid gear oils
rated GL5 or GL6 may also be used. @5. Install and tighten the filler bolt to
the specified torque.
6. Check the final gear case for oil
leakage. If oil is leaking, check for
the cause.

3. Proper oil level
Tightening torque:
Final gear oil drain bolt:

Recommended final gear oil:
Hypoid gear oil SAE 80 (API GL4)
or multigrade hypoid gear oil SAE
80W-90
Oil quantity:
0.2 L

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:
l
When checking the fluid level,
make sure that the top of the mas-
ter cylinder or brake fluid reservoir
is level.
l
Use only the recommended quali-
ty brake fluid, otherwise the rubber
seals may deteriorate, causing
leakage and poor braking perfor-
mance.
l
Refill with the same type of brake
fluid. Mixing fluids may result in a
harmful chemical reaction and
lead to poor braking performance.
l
Be careful that water does not en-
ter the master cylinder when refill-
ing. Water will significantly lower
the boiling point of the fluid and
may result in vapor lock.
l
Brake fluid may deteriorate paint-
ed surfaces or plastic parts. Al-
ways clean up spilled fluid
immediately.
l
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-fric-

“ENERGY CONSERVING II”) contain anti-friction addi-
tives which will cause clutch and/or starter clutch slip-
page, resulting in reduced component life and poor
engine performance.
