WARNING
l
Check the brake lever free play.
Be sure the brake is working
properly.
l
A soft or spongy feeling in the
brake lever can indicate the
presence of air in the brake
system. This air must be re-
moved by bleeding the brake
system before the motorcycle
is operated. Air in the system
will cause greatly diminished
braking capability and can re-
sult in loss of control and anaccident. Have a Yamaha dealer
inspect and bleed the system if
necessary.

EAU00731
Inspecting the brake fluid
levelInsufficient brake fluid may let air enter
the brake system, possibly causing the
brakes to become ineffective.
Before riding, check that the brake flu-
id is above the minimum level and re-
plenish when necessary. Observe
these precautions:l
When checking the fluid level,
make sure the top of the master
cylinder is level by turning the
handlebars.
l
Use only the designated quality
brake fluid. Otherwise, the rubber
seals may deteriorate, causing
leakage and poor brake perfor-
mance.
l
Refill with the same type of brake
fluid. Mixing fluids may result in a
harmful chemical reaction and
lead to poor brake performance.
l
Be careful that water does not en-
ter the master cylinder when refill-
ing. Water will significantly lower
the boiling point of the fluid and
may result in vapor lock.
l
Brake fluid may deteriorate paint-
ed surfaces or plastic parts. Al-
ways clean up spilled fluid
immediately.
l
Have a Yamaha dealer check the
cause if the brake fluid level goes
down. Recommended brake fluid: DOT 4
EAU00742
Brake fluid replacementThe brake fluid should be replaced
only by trained Yamaha service per-
sonnel. Have the Yamaha dealer re-
place the following components during
periodic maintenance or when they are
damaged or leaking:l
oil seals (every two years)
l
brake hoses (every four years)

Cable inspection and
lubrication
EW000112
WARNING
Damage to the outer housing of ca-
bles may lead to internal rusting
and interfere with the cable move-
ment. Replace damaged cables as
soon as possible to prevent unsafeconditions.
Lubricate the cables and cable ends. If
a cable does not operate smoothly,
ask a Yamaha dealer to replace it.
Recommended lubricant:
Engine oil
EAU00773
Throttle cable and grip lubri-
cationThe throttle twist grip assembly should
be greased at the time that the cable is
lubricated, since the grip must be re-
moved 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 disassembled, coat the
metal surface of the grip assembly with
a suitable all-purpose grease.

ment is found with the front fork,consult a Yamaha dealer.
EAU00794
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 easier if the
front wheel is removed.

If the motorcycle is equipped with
optional electrical accessories,
the battery tends to discharge
more quickly, so be sure to re-
charge it periodically.
