8In 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 specified. In
addition, do not use oils labeled “ENERGY
CONSERVING II” or higher.
8Make sure that no foreign material enters
the crankcase.
14. Start the engine, and then let it idle for sev-
eral minutes while checking it for oil leak-
age. If oil is leaking, immediately turn the
engine off and check for the cause.
15. Turn the engine off, and then check the oil
level and correct it if necessary.
16. Install the engine guard by installing the
bolts, and then tighten them to the speci-
fied torque.

Observe these precautions:
8When checking the brake fluid level, make
sure the top of the brake fluid reservoir is
level.
8Use only the designated quality brake fluid,
otherwise, the rubber seals may deteriorate,
causing leakage and poor brake performance.
8Refill with the same type of brake fluid. Mixing
fluids may result in a harmful chemical reac-
tion and lead to poor brake performance.
8Be 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.
8Brake fluid may deteriorate painted surfaces
or plastic parts. Always clean up spilled fluid
immediately.
8Have a Yamaha dealer check the cause if the
brake fluid level goes down.Recommended brake fluid: DOT 4
