8Use only the designated quality
brake fluid. Otherwise, the rub-
ber seals may deteriorate, caus-
ing leakage and poor brake per-
formance.NOTE:

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

Remove the cap and inspect the
pads. If the thickness is less than the
specified value, have a Yamaha deal-
er replace the pads.1.Wear limit: 0.8 mm

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.

replace the following components
during periodic maintenance or when
they are damaged or leaking:

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)

in the same position for proper
wheel alignment. To tighten the

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.

BatteryThis motorcycle is equipped with a
sealed-type battery. Therefore it is
not necessary to check the elec-
trolyte or fill the battery with distilled
water.

If the battery seems to have dis-
charged, consult a Yamaha deal-
er.

If the motorcycle is equipped
with optional electrical acces-
sories, the battery tends to dis-
charge more quickly, so be sure
to recharge it periodically.

cCNever try to remove the sealing
caps of the battery cells. The bat-
tery will be damaged.

Completely recharge the bat-
tery before storing. Storing a
discharged battery can cause
permanent battery damage.
8 8
Use a battery charger
designed for a sealed-type
(MF) battery. Using a conven-
tional battery charger will
cause battery damage. If you
do not have a sealed-type bat-
tery charger, contact your
Yamaha dealer.
8 8
Always make sure the connec-
tions are correct when rein-
stalling the battery.

EYES: Flush with water for 15
minutes and get prompt med-
ical attention.
Batteries produce explosive
gases. Keep sparks, flame, ciga-
rettes etc., away. Ventilate when
charging or using in an enclosed
space. Always shield your eyes
when working near batteries.
