the adjusting bolt in direction (a). To decrease
the throttle cable free play, turn the adjusting

EBU24060Valve clearance The valve clearance changes with use, resulting in
improper air-fuel mixture and/or engine noise. To
prevent this from occurring, the valve clearancemust be adjusted by a Yamaha dealer at the inter-
vals specified in the periodic maintenance and lu-
brication chart.
EBU24070Adjusting the drive select lever safety
system cable The drive select lever safety system cable stretch-
es with use, which can result in improper function.
Therefore, the safety system cable should be
checked and adjusted at the intervals specified in
the periodic maintenance and lubrication chart.EBU27470Checking the front and rear brake pads The front and rear brake pads must be checked for
wear at the intervals specified in the periodic main-
tenance and lubrication chart. Each brake pad is
provided with a wear indicator groove, which al-
lows you to check the brake pad wear without hav-
ing to disassemble the brake. If a brake pad has
worn to the point that the wear indicator groove has
almost disappeared, have a Yamaha dealer re-
place the brake pads as a set.

tors The rear brake hoses protectors must be checked
for wear at the intervals specified in the periodic
maintenance and lubrication chart. Each brake
hose protector is provided with a wear indicator. If
a protector wears to the point that its indicator be-
comes visible, have a Yamaha dealer replace the
protector.

brake system, possibly causing it to become inef-
fective.Before riding, check that the brake fluid is above
the minimum level mark and replenish if neces-
sary. A low brake fluid level may indicate worn
brake pads and/or brake system leakage. If the
brake fluid level is low, be sure to check the brake
pads for wear and the brake system for leakage.

Observe these precautions:

When checking the fluid level, make sure that
the top of the brake fluid reservoir is level.
Use only the recommended quality brake fluid,
otherwise the rubber seals may deteriorate,
causing leakage and poor braking performance.
Refill with the same type of brake fluid. Mixing
fluids may result in a harmful chemical reaction
and lead to poor braking performance.

Be 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.
Brake fluid may deteriorate painted surfaces or
plastic parts. Always clean up spilled fluid imme-
diately.
As the brake pads wear, it is normal for the brake
fluid level to gradually go down. However, if the
brake fluid level goes down suddenly, have a
Yamaha dealer check the cause.EBU24290Changing the brake fluid Have a Yamaha dealer change the brake fluid at
the intervals specified in the NOTE after the peri-
odic maintenance and lubrication chart. In addi-
tion, have the oil seals of the master cylinders and
calipers as well as the brake hoses replaced at the
intervals listed below or whenever they are dam-
aged or leaking.
Oil seals: Replace every two years.
Brake hoses: Replace every four years.

EBU27770Checking the front and rear brake lever
free play The front and rear brake lever free play must be
checked at the intervals specified in the periodic
maintenance and lubrication chart. Each brake le-
ver should have a free play of zero mm (zero in) as
shown. If the free play is incorrect, have a Yamaha
dealer check the brake system.

WARNING
EWB02070Operating with improperly serviced or adjust-
ed brakes could cause loss of braking ability,
which could lead to an accident.
After servicing:
Make sure the brakes operate smoothly and
that the free play is correct.
Make sure the brakes do not drag.
Make sure the brakes are not spongy. All air
must be bled from the brake system.

the following order whenever adjusting the rear
brake.
Before adjusting the brake pedal free play and
checking the brake pedal position, check therear brake pads for wear.
Adjusting the brake pedal free play
The brake pedal free play should measure 0.0–5.0
mm (0.00–0.20 in) as shown. If the free play is in-
correct, adjust it as follows.1. Remove panel H. (See page 8-8.)
