wA soft or spongy feeling in the
brake pedal can indicate the pres-
ence of air in the brake system.
This air must be removed by
bleeding the brake system before
the motorcycle is operated. Air in
the system will cause greatly
diminished braking capability and
can result in loss of control and an
accident. Have a Yamaha dealer
inspect and bleed the system if
necessary.

Checking the front and rear
brake padsA wear indicator is provided on each
brake. This indicator allows checking
of brake pad wear without disassem-
bling the brake. Apply the brake and
inspect the wear indicator. If the
brake pads are worn to wear limit,
have a Yamaha dealer to replace the
pads.

Front brake
Wear indicator grooves are provided
on each brake pad. These indicators
allow checking of brake pad wear
without disassembling the brake.
Inspect the grooves. If they have
almost disappeared, ask a Yamaha
dealer to replace the pads.

Inspecting the brake fluid
levelInsufficient brake fluid may let air
enter the brake system, possibly
causing the brakes to become inef-
fective.
Before riding, check that the brake
fluid is above the minimum level and
replenish when necessary.
Observe these precautions:
8When checking the fluid level,
make sure the top of the master
cylinder is level by turning the
handlebars.1.Minimum level mark

8Refill with the same type of brake
fluid. Mixing fluids may result in a
harmful chemical reaction and
lead to poor brake performance.
8Be careful that water does not
enter the master cylinder when
refilling. Water will significantly
lower the boiling point of the fluid
and may result in vapor lock.
8Brake fluid may deteriorate paint-
ed surfaces or plastic parts.
Always clean up spilled fluid
immediately.
8Have a Yamaha dealer check
the cause if the brake fluid level
goes down.

Drive chain slack checkNOTE:
Spin the wheel several times and find
the tightest position of the chain.
Check and/or adjust the chain slack
while itÕs in this tightest position.To check the chain slack the motor-
cycle must be held straight up with
both wheels on the ground and with-
out rider. Check the slack at the posi-
tion shown in the illustration. Normal
slack is approximately 30 ~ 40 mm. If
the slack exceeds 40 mm, adjust.

Drive chain lubricationThe chain consists of many parts
which work with each other. If the
chain is not maintained properly, it
will wear out quickly. Therefore, the
chain must be serviced regularly.
This service is especially necessary
when riding in dusty areas. This
motorcycle is equipped with a sealed
type chain. Steam cleaning, high-
pressure washers, and solvents can
damage the drive chain, so do not
use these for cleaning it. Use only
kerosene to clean the drive chain.
Wipe it dry, and thoroughly lubricate it
with SAE 30 ~ 50W motor oil. Do not
use any other lubricants on the drive
chain. They may contain solvents
that could damage the sealed chain. Tightening torque:
Axle nut:
105 Nm (10.5 m
0kg)
Caliper bracket bolt:
48 Nm (4.8 m
0kg)

Throttle cable and grip
lubricationThe throttle twist grip assembly
should be greased at the time that
the cable is lubricated, since the grip
must be removed to get at the end of
the throttle cable. After removing the
screws, hold the end of the cable up
in the air and put in several drops of
lubricant. With the throttle grip disas-
sembled, coat the metal surface of
the grip assembly with a suitable all-
purpose grease.

If a cable does not operate smoothly,
ask a Yamaha dealer to replace it.

Wheel bearingsIf there is play in the front or rear
wheel hub or if the wheel does not
turn smoothly, have a Yamaha dealer
inspect the wheel bearings.

Steering inspectionPeriodically inspect the condition of
the steering. Worn out or loose steer-
ing bearings may be dangerous.
Place a stand under the engine to
raise the front wheel off the ground.
Hold the lower end of the front forks
and try to move them forward and
backward. If any free play can be felt,
ask a Yamaha dealer to inspect and
adjust the steering. Inspection is eas-
ier if the front wheel is removed.
