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.

level and correct it if necessary.

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.
