Inspecting the brake fluid level
Insufficient brake fluid may let air enter the brake system,
possibly causing the brakes to become ineffective. Before
riding, check that the brake fluid is above the lower level
and replenish when necessary. Observe these precautions:
1. When checking the fluid level, make sure the top of the
master cylinder is level by turning the handlebars.
2. Use only the designated quality brake fluid. Otherwise,
the rubber seals may deteriorate, causing leakage and
poor brake performance.
Recommended brake fluid:
DOT #4
NOTE:
If DOT #4 is not available, #3 can be used.
1. Lower level
3. Refill with the same type of brake fluid. Mixing fluids
may result in a harmful reaction and lead to poor brake
performance.
4. Be 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.
5. Brake fluid may deteriorate painted surfaces or plastic
parts. Always clean up spilled fluid immediately.
6. Have a Yamaha dealer check the cause if the brake
fluid level goes down.

Brake fluid replacement
1. Complete fluid replacement should be done only bytrained service personnel.
2. Have a Yamaha dealer replace the following components during periodic maintenance or when they
are damaged or leaking.
a. Replace all rubber seals every two years.
b. Replace all hoses every four years.
!%Clutch adjustment
The clutch lever free play should be adjusted to 10 ~ 15
mm (0.4 ~ 0.6 in) at the clutch lever end. If the free play is
incorrect, adjust as follows.
1. Loosen the locknut at the handlebar.
2. Turn the adjuster in or out until proper lever free play is
obtained.
3. Tighten the locknut.
4. If the free play is still incorrect, make an adjustment at the crankcase side.
NOTE:
If proper adjustment cannot be obtained or the clutch does
not work correctly, ask a Yamaha dealer to inspect the

2. Loosen the axle nut.
3. Loosen the chain adjusting locknuts on each chainpuller. To tighten the chain, turn the chain adjusting nuts
in direction .To loosen the chain turn the chain
adjusting nuts in direction and push the wheel
forward. Turn each chain adjusting nut exactly the same
amount to maintain correct axle alignment. There are
marks on each chain puller. Use these marks to align
the rear wheel. Too little chain slack will overload the engine and other vital
parts. Keep the slack within the specified limits.
To maintain correct axle alignment, Ensure the notch on
the adjuster is on the same mark on left and right side
4. After adjusting, be sure to tighten each chain adjusting
locknut. The tighten the axle nut to the specified torque
Axle nut torque: 91 N.m (9.1 Kgf.m, 66 lbf.ft)
Locknut torque: 15 N.m (1.5 Kgf.m, 11 lbf.ft)
