Air filter
This model’s air filter is equipped with a disposable oil-coated paper element, which must not be cleaned with com-
pressed air to avoid damaging it.
The air filter element needs to be replaced more frequently when riding in unusually wet or dusty areas.

Clutch lever Since this model is equipped with a hy-
draulic clutch, adjusting the clutch lever
free play is not needed. However, it is
necessary to check the clutch fluid level
and check the hydraulic system for
leakage before each ride. If the clutch
lever free play does become excessive,
and shifting becomes rough or clutch
slippage occurs, causing poor acceler-
ation, there may be air in the clutch sys-
tem. If there is air in the hydraulic
system, have a Yamaha dealer bleed
the system before operating the motor-
cycle.
EAU22270
Adjusting the rear brake light
switch The rear brake light switch, which is ac-
tivated by the brake pedal, is properly
adjusted when the brake light comes
on just before braking takes effect. If
necessary, adjust the brake light switch
as follows.
Turn the adjusting nut while holding the
rear brake light switch in place. To
make the brake light come on earlier,
turn the adjusting nut in direction (a). To
make the brake light come on later, turn
the adjusting nut in direction (b).

Checking the front and rear
brake pads The front and rear brake pads must be
checked for wear at the intervals spec-
ified in the periodic maintenance and
lubrication chart.
EAU22430
Front brake pads
Each front brake pad is provided with
wear indicator grooves, which allow
you to check the brake pad wear with-
out having to disassemble 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

peared, have a Yamaha dealer replace
the brake pads as a set.
EAU22500
Rear brake pads
Check each rear brake pad for damage
and measure the lining thickness. If a
brake pad is damaged or if the lining
thickness is less than 0.8 mm (0.03 in),
have a Yamaha dealer replace the
brake pads as a set.

Checking the brake and clutch
fluid levels Front brake

Insufficient brake or clutch fluid may al-
low air to enter the brake or clutch sys-
tems, possibly causing them to become
ineffective.
NOTE:The rear brake fluid reservoir is locatedunder the rider seat. (See page 3-15.)
Before riding, check that the brake and
clutch fluids are above the minimum
level marks and replenish if necessary.
A low brake or clutch fluid level may in-
dicate brake or clutch system leakage
and/or worn brake pads. If the brake or
clutch levels are low, be sure to check
the brake or clutch systems for leakage
and the brake pads for wear.

6 Observe these precautions:


When checking the brake and
clutch fluid levels, make sure that
the top of each reservoir is level.


Use only the recommended quality
brake fluid, otherwise the rubber
seals may deteriorate, causing
leakage and poor braking or clutch
performance.


Refill with the same type of brake
fluid. Mixing fluids may result in a
harmful chemical reaction and
lead to poor braking or clutch per-
formance.


Be careful that water does not en-
ter the brake or clutch fluid reser-
voir when refilling. Water will
significantly lower the boiling point
of the fluid and may result in vapor
lock.


Brake fluid may deteriorate paint-
ed surfaces or plastic parts. Al-
ways clean up spilled fluid
immediately.


As the brake pads wear, it is nor-
mal for the brake fluid level to grad-
ually go down. However, if the
brake fluid level goes down sud-
denly, have a Yamaha dealer
check the cause.
EAU22750
Changing the brake and
clutch fluids Have a Yamaha dealer change the
brake and clutch fluids at the intervals
specified in the NOTE after the periodic
maintenance and lubrication chart. In
addition, have the oil seals of the brake
and clutch master cylinders and cali-
pers as well as the brake and clutch
hoses replaced at the intervals listed
below or whenever they are damaged
or leaking.

Oil seals: Replace every two
years.


Brake and clutch hoses: Replace
every four years.

Checking and lubricating the
brake and clutch levers Brake lever
Clutch lever
The operation of the brake and clutch
levers should be checked before each
ride, and the lever pivots should be lu-
bricated if necessary.

Checking and lubricating the
sidestand The operation of the sidestand should
be checked before each ride, and the
sidestand pivot and metal-to-metal
contact surfaces should be lubricated if
necessary.
WARNING

If the sidestand does not move up
and down smoothly, have a Yamahadealer check or repair it.
