5. Fill the differential gear case with the speci-
fied amount of the recommended oil.NOTE:_

Do not exceed the specified differential gear
oil quantity when filling. Overfilling will cause
the oil to seep out of the breather hose during
and after riding.


The differential gear oil level cannot be
checked. The differential gear case capacity
is greater than the recommended oil quantity,
therefore the oil level cannot be accurately
checked from the oil filler cap hole.
_
Recommended oil:
SAE 80 API GL-4 Hypoid gear oil
Oil quantity:
0.35 L

Refill with the same type of brake fluid. Mixing
fluids may result in a harmful chemical reaction
and lead to poor brake performance.


Be careful that water does not enter the brake
fluid reservoir when refilling. Water will signifi-
cantly lower the boiling point of the fluid and
may result in vapor lock.


Brake fluid may deteriorate painted surfaces or
plastic parts. Always clean up spilled fluid im-
mediately.


Have a Yamaha dealer check the cause if the
brake fluid level goes down.
