BRAKE AIR BLEEDING
Any air which may have been trapped in the brake
fluid circuit must be bled completely. If the brake lever
feels spongy or weak, then most likely there is air in
the hydraulic circuit. To bleed the air from the front
brake, use the following procedure.
Connect a clear hose to the air bleeder valve and run
the hose into a suitable clear container. Pour approxi-
mately 1/2 in of brake fluid into the container so that
the end of the clear hose is submerged and cannot
draw any additional air back into the circuit during the
air bleeding servicing. Then close the valve, pump
and squeeze the lever, and open the valve while
squeezing brake lever. Repeat this process until the
fluid flowing into the receptacle no longer contains air
bubbles.
After bleeding the brake circuit, tighten the bleeder
valve to the specified torque. Replace the rubber pro-
tective cap. Be sure to check the brake fluid level in
the reservoir tank.

THROTTLE CABLE
Check the throttle cable play at the throttle grip.
Throttle cable play: 2.0–4.0 mm (0.08–0.16 in)
If adjustment is necessary, carry out the procedure
below:
1. Loosen the throttle cable adjuster lock nut
A
.
2. Turn the adjuster
B
in or out until the correct play.
3. Tighten the lock nut
A
while holding the adjuster.

NOTE:
Do not drop brake fluid level below lower level
line while bleeding air.
After the adjustment is completed, check that
handlebar movement does not raise the
engine idle speed and that the throttle grip
returns smoothly and automatically.
