Adjusting the clutch
For proper operation the clutch must be engaged with a set minimum clearance. To achieve the
minimum clearance use the 2 adjusters, one of which is located on the handlebars (Fig. 9) and the
other on the engine casing (Fig. 6, Figure 12).
Adjusting the brakes
Front brake (putting back into operation after maintenance or repairs)
Tighten all sealing joints, pour brake fluid into the brake master cylinder.
Repeatedly pressing the lever front brakes delivers brake fluid to the entire brake system
(to speed up the operation, carefully open and close the caliper brake fluid bleed screw while
operating the brake lever). To fill the entire system with fluid, the brake must be properly bled. Fit a
length of transparent tube to the bleed screw on the left side of the caliper brake slide and place the
other end of the tube into a glass of brake fluid. After operating the brake lever tighten the bleed
screw again. This operation must be performed until only clear fluid without bubbles is seen in the
transparent tube while brake lever is being operated. Ensure that the master cylinder is kept topped-
up during this operation. Adjust the stop-switch adjust so that it is just in contact with the brake lever
while not in use, but does not trigger the brake light.
ATTENTION!
Repairing front disc brakes: for safety reasons refer to a workshop.
Rear brake
1
st
:
Adjust rear brake by turning the wing nut (Fig. 19).
2
nd
:
Wing nut is to be tightened until brake shoes begin to operate. Then, about 1.5 turns is
released.
Proper adjustment of the rear brake is a prerequisite for proper operation of the brake switch.
Adjusting the front brake-lever screw to adjust the bias control of the main cylinder, free play of
between 0.3 and 0.5 mm. There should be no sponginess in the system. Adjust the brake light switch
so that the brake light comes on before the brake is applied.
Adjusting the rear brake light switch
1st
Remove the locking pin of the double-ended Bowden cable, which is attached to the gear
lever and rear brake (see Figure 6, Figure 13).
2nd
by resetting the appropriate endings of the double-ended find the location at which the switch
turns on the brake light as the brake lever is being operated, and still reliably returns to the OFF
position when pressure is removed.
3
rd
:
Ensure proper fitting of cotter pins.
Chain Tensioning and lubrication
Place the motorcycle on its stand, loosen the rear wheel spindle nut and the nut on the rear sprocket
side. Then loosen the chain tensioners on both sides. Tension the chain gradually by tightening bolt
tensioners to the same value. The chain should be tensioned so that when lifted up at the lateral
reinforcement on the swinging arm its deflection should be 20 - 30 mm (Fig. 16, Figure 17).
ATTENTION!
It is necessary to maintain alignment (make sure front and rear wheels are in line to avoid biasing the
rear wheel to one side or the other). Alignment has an effect on driving the motorcycle.
