CAUTION:_

In order to prevent clutch slippage (since
the engine oil also lubricates the clutch),
do not mix any chemical additives. Do not
use oils with a diesel specification of
“CD” or oils of a higher quality than spec-
ified. In addition, do not use oils labeled
“ENERGY CONSERVING II” or higher.


Make sure that no foreign material enters
the crankcase.
_12. Start the engine and warm it up for several
minutes. While warming up, check for oil
leakage. If oil leakage is found, turn the en-
gine off immediately and check for the cause.
13. Turn the engine off, and then check the oil
level and correct it if necessary.
14. Install panel F.

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 master
cylinder reservoirs when refilling. Water will sig-
nificantly 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.
