Adjustment
Loosen the rear axle nut and locknut, turn both adjusting bolts until the chain slack
meets the standard, and make sure left and right adjusters align with the same index marks.
After checking, tighten up the rear axle nut with a torque of 50
60N.m.
NOTE Turning the adjusting nut in direction A will increase the chain slack, and in
direction B decrease the slack.
Check the chain for slack
If slack of chain is changed, it is necessary to relocate the rear wheel, for adjustment
will affect the rear brake pedal free play.
Lubrication
Pull out the chain clip with pliers, remove the joint and chain. Wash the chain in cleansing
solution and dry it in the air. Check the chain including link plates, bushings, and rollers
for damage, cracks, wear-out. Replace if necessary. Lubricate the chain, then reinstall and
adjust it.
CAUTION The chain clip should be so installed as to make sure that its closed end faces
the direction of wheel rotation.
FRONT BRAKE
Front Disk Brake (Fig. 35)
Fr. brake lever Brake main cylinder Sight glass Screw Cover Brake calliper
The front brake lever is located at the right handlebar. The distance the front brake lever
moves before the brake starts to engage is called free play, which should be 10-20mm
(Fig.
35).
Place the motorcycle on the level ground. Check the brake fluid level through the sight
glass. If the fluid level is below the LOWER, loosen the cylinder cover screws, remove
the cover, add brake fluid up to the UPPER level mark.
Air Bleeding
If the brake lever free play becomes excessive and the brake pads are not worn beyond its
minimum depth, there is probably air in the brake system and bleed it as follows:
Pump the front brake lever, then gently loosen the bleed valve while holding the lever.
Take care to tighten up the bleed valve as soon as flowing fluid. Repeat above the proce-
dure until the system is completely bled.
Apply the breke several times and check for free wheel rotation after the brake lever is
released.
WARNING Apply only specified brake fluid, or braking effectiveness and riding
safety will be affected adversely. Do not allow contaminants such as dirt or water to
enter the brake fluid tank. Brake fluid may cause irritation. Avoid contact with skin
or eyes. In case of contact, flush thoroughly with water.
