TIPBe sure to wipe off spilled oil on any parts af-
ter the engine and exhaust system have
cooled down. NOTICEECB00301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
specified. In addition, do not use oils la-
beled “ENERGY CONSERVING II” or
higher.
 Make sure that no foreign material en-
ters the crankcase. 14. Start the engine, and then let it idle for
several minutes while checking it for oil
leakage. If oil is leaking, immediately turn
the engine off and check for the cause.

the brim of the filler hole. 3. If the oil is below the brim of the filler hole,
add sufficient oil of the recommended
type to raise it to the correct level.
NOTICE: Be sure no foreign material
enters the final gear case.

Clean the filler cap before removing. Use
only DOT 4 brake fluid from a sealed
container.
 Use only the specified brake fluid; other-
wise, the rubber seals may deteriorate,
causing leakage.
 Refill with the same type of brake fluid.
Adding a brake fluid other than DOT 4
may result in a harmful chemical reac-
tion.
 Be careful that water does not enter the
brake fluid reservoir when refilling. Wa-
ter will significantly lower the boiling
point of the fluid and may result in vapor
lock. NOTICEECB01161Brake fluid may damage painted surfaces
or plastic parts. Always clean up spilled
fluid immediately.
As the brake pads wear, it is normal for the
brake fluid level to gradually go down. A low
brake fluid level may indicate worn brake
pads and/or brake system leakage; therefore,
be sure to check the brake pads for wear and
the brake system for leakage. If the brake fluid
level goes down suddenly, have a Yamaha
dealer check the cause before further riding.EBU32520Brake fluid replacementComplete fluid replacement should be done
only by trained Yamaha service personnel.
Have a Yamaha dealer replace the following
components during periodic maintenance or
when they are damaged or leaking.
Replace the oil seals every two years.
 Replace the brake hoses every four years.EBU32530Checking the brake pedalHave a Yamaha dealer check the brakes at
the intervals specified in the periodic mainte-
nance and lubrication chart. There should be
