9Owners are personally responsible for their vehicle’s condition. Your motorcycle/scooter’s vital functions can start to
deteriorate quickly and unexpectedly, even if it remains unused (for instance, if it is exposed to the elements). Any dam-
age, fluid leak or loss of tire pressure could have serious consequences. Therefore, it is very important that, in addition
to a thorough visual inspection, you check the following points before each ride.

Always check the tires before operat-
ing the motorcycle. If center tread
depth reaches the limit as shown, if
the tire has a nail or glass fragments
in it, or if the side wall is cracked,
contact a Yamaha dealer immediate-
ly and have the tire replaced.

Operating the motorcycle with
excessively worn tires decrease
riding stability and can lead to loss
of control. Have excessively worn
tires replaced by a Yamaha dealer
immediately. Brakes, tires, and
related wheel parts replacement
should be left to a Yamaha Service
Technician.

EAU00687Wheels
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.

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.
Check and/or adjust the chain slack
while it’s in this tightest position.

9 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 25 ~ 40 mm. If
the slack exceeds 40 mm, adjust.
EAU00762Drive chain slack adjustment
1. Loosen the axle nut.
2. Loosen the locknuts on each
side. To tighten the chain, turn
the chain adjusting nuts in direc-
tiona. To loosen the chain, turn
the adjusting nuts in directionb
and push the wheel forward.

Too little chain slack will overload
the engine and other vital parts.
Keep the slack within the specified
limits.
3. After adjusting, tighten the lock-
nuts. Then tighten the axle nut to
the specified torque.
