6fore operating the motorcycle. Air in
the hydraulic system will diminish
the braking performance, which may
result in loss of control and an acci-
dent.
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).
EAU22390
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.
EAU22410
Front brake pads
Each front brake pad is provided with a
wear indicator, which allows you to
check the brake pad wear without hav-
ing to disassemble the brake. To check
the brake pad wear, check the position
of the wear indicator while applying the
brake. If a brake pad has worn to the

6 point that the wear indicator almost
touches the brake disc, 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 1.0 mm (0.04 in),
have a Yamaha dealer replace the
brake pads as a set.
EAU22580
Checking the brake fluid level Front brake
Rear brake
Insufficient brake fluid may allow air to
enter the brake system, possibly caus-
ing it to become ineffective.Before riding, check that the brake fluid
is above the minimum level mark and
replenish if necessary. 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 perfor-
mance.


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 en-
ter the brake fluid reservoir 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.
EAU22730
Changing the brake fluid Have a Yamaha dealer change the
brake fluid at the intervals specified in
the NOTE after the periodic mainte-
nance and lubrication chart. In addition,
have the oil seals of the master cylin-
ders and calipers as well as the brake
hoses replaced at the intervals listed
below or whenever they are damaged
or leaking.

Oil seals: Replace every two
years.


Brake hoses: Replace every four
years.
EAU22760
Drive chain slack The drive chain slack should be
checked before each ride and adjusted
if necessary.
EAU22770
To check the drive chain slack
1. Place the motorcycle on a level
surface and hold it in an upright po-
sition.NOTE:When checking and adjusting the drive
chain slack, the motorcycle should be
positioned straight up and there shouldbe no weight on it.
2. Shift the transmission into the neu-
tral position.
3. Move the rear wheel by pushing
the motorcycle to locate the tight-
est portion of the drive chain, and
then measure the drive chain slack
as shown.Drive chain slack:
35.0–45.0 mm (1.38–1.77 in)

Do not apply the brake after the
brake calipers have been removed,
otherwise the brake pads will beforced shut.

To install the front wheel
1. Lift the wheel up between the fork
legs.
2. Insert the wheel axle.
3. Lower the front wheel so that it is
on the ground.
4. Install the brake calipers by install-
ing the bolts, and then tightening
them to the specified torque.
NOTE:Make sure that there is enough space
between the brake pads before install-
ing the brake calipers onto the brakediscs.
5. Install the brake hose holders by
installing the bolts.
6. Secure the wheel axle by installing
the axle bolt, and then tightening
the wheel axle to the specified
torque.NOTE:While tightening the wheel axle, holdthe axle bolt to keep it from turning.
7. Tighten wheel axle pinch bolt B,
and then tighten pinch bolt A to the
specified torque.8. Retighten pinch bolt B to the spec-
ified torque.
9. Tap the outer side of the left fork
leg with a rubber mallet to align it
with the end of the wheel axle.
10. Tighten wheel axle pinch bolt D,
and then tighten pinch bolt C to the
specified torque.
11. Retighten pinch bolt D to the spec-
ified torque.

To install the rear wheel
1. Install the wheel and the brake cal-
iper bracket by inserting the wheel
axle from the left-hand side.NOTE:

Be sure to insert the retainer on the
brake caliper bracket into the slot
in the swingarm.


Make sure that there is enough
space between the brake pads be-fore installing the wheel.
2. Install the drive chain onto the rear
sprocket, and then adjust the drive
chain slack. (See page 6-26.)
3. Install the axle nut, and then lower
the rear wheel so that it is on the
ground.
4. Tighten the axle nut to the speci-
fied torque.

Troubleshooting Although Yamaha motorcycles receive
a thorough inspection before shipment
from the factory, trouble may occur dur-
ing operation. Any problem in the fuel,
compression, or ignition systems, for
example, can cause poor starting and
loss of power.
The following troubleshooting charts
represent quick and easy procedures
for checking these vital systems your-
self. However, should your motorcycle
require any repair, take it to a Yamaha
dealer, whose skilled technicians have
the necessary tools, experience, and
know-how to service the motorcycle
properly.
Use only genuine Yamaha replace-
ment parts. Imitation parts may look like
Yamaha parts, but they are often inferi-
or, have a shorter service life and can
lead to expensive repair bills.
