EBU32460Valve clearanceThe correct valve clearance changes with
use, resulting in improper fuel/air supply or
engine noise. To prevent this, the valve clear-
ance must be adjusted regularly. This adjust-
ment however, should be left to a
professional Yamaha service technician.EBU32470BrakesReplacement of brake components requires
professional knowledge. Brake service
should be performed by a Yamaha dealer.
WARNING
EWB02572Operating with improperly serviced or ad-
justed brakes could lead to a loss in brak-
ing ability and an accident.
EBU32480Checking the front and rear brake padsEach brake pad is provided with wear indica-
tor grooves, which allow you to check the
brake pad wear without having to disassem-
ble the brake. To check the brake pad wear,
check the wear indicator grooves. If a brake
pad has worn to the point that the wear indi-
cator grooves have almost disappeared, have
a Yamaha dealer replace the brake pads as a
set.
The wheels need to be removed to check the
brake pads. (See pages 8-44, 8-46 for wheel
removal and installation procedures.)

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
