To ensure maximum performance,
long service, and safe operation, note
the following:
8Always inspect the wheels
before a ride. Check for cracks,
bends, or warpage of the wheels.
If any abnormal condition exists
in a wheel, consult a Yamaha
dealer. Do not attempt even
small repairs to the wheel. If a
wheel is deformed or cracked, it
must be replaced.
8Tires and wheels should be bal-
anced whenever either one is
changed or replaced. Failure to
have a wheel balanced can
result in poor performance,
adverse handling characteristics,
and shortened tire life.
8Ride at moderate speeds after
changing a tire since the tire sur-
face must first be broken in for it
to develop its optimal character-
istics.

working properly.

A soft or spongy feeling in the
brake lever can indicate the
presence 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.

98Refill 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.
EAU00742Brake fluid replacement
The brake fluid should be replaced
only by trained Yamaha service per-
sonnel. Have the Yamaha dealer
replace the following components
during periodic maintenance or when
they are damaged or leaking:
8oil seals (every two years)
8brake hoses (every four years)
EAU00744Drive chain slack check
NOTE:
Spin the wheel several times and find
the tightest position of the chain.
