65. 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.
NOTE:@ When adding oil, be careful not to over-
fill the engine; the oil level rises faster
starting from the half level portion on
the dipstick. @6. Insert the dipstick into the oil filler
hole, and then tighten the oil filler
cap.
7. Install the rider seat.

Transfer case oil The transfer case oil level should be
checked before each ride. In addition,
the oil must be changed at the intervals
specified in the periodic maintenance
and lubrication chart.
To check the transfer case 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. Remove the oil check bolt, and
then check the oil level in the
transfer case.NOTE:@ The oil should be at the brim of the
check hole. @3. If the oil is below the brim of the
check hole, remove the oil filler
cap, add sufficient oil of the rec-
ommended type to raise it to the
correct level, and then install the
oil filler cap.
4. Install the oil check bolt, and then
tighten it to the specified torque.To change the transfer case oil
1. Place an oil pan under the transfer
case to collect the used oil.
2. Remove the drain bolt and the
check bolt to drain the oil from the
transfer case.
3. Install the drain bolt and the check
bolt, and then tighten the drain bolt
to the specified torque.

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-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-
ing in reduced component life and poor engine performance.
