8.15. Rear Stop Light Switch
The stop light switch must be set in such a way that the stop light goes on immediately at the start of the brake
control lever travel.
It is not possible to adjust the stop light switch. Replace it, if need be, or contact the special service.
8.16. Front Stop Light Switch
The stop light must go on immmediately. when pressing the hand lever of the front wheel brake.
It is not possible to adjust the stop light switch. Replace it, if need be, or contact the special service.
8.17. Chain Tightening
It is necessary to check the chain tightening during operation.
Before the chain tightening check or adjustment, turn the wheel several times. During this turning
check the chain tightening and find the point, where the chain is tightened most of all. (Carry out its
adjustment in this position.)
At the check the motorcycle must stand vertically to the ground, with both wheels on it, and without a
driver.
It must be possible to slag the chain within 20 to 30 mm with the unloaded motorcycle. If the sag
exceeds 30 mm, adjust it (Figure 34).
Tighten the chain as follows:
Release the wheel axle nut on the right side.
Shift both chain tighteners simultaneously (e.g. by 1/2 of nut turns) to maintain the wheel trace (Figure
35).
Excessive tightening of the chain will overload the engine and other movable parts.
After the adjustment check the mutual position of front and rear wheels by means of a straight bar (The
bar is attached onto the front and rear wheels). Make a correction, if need be, by the chain tighteners.
After the adjustment tighten properly the tighteners locking nuts as well as the wheel axle nuts.
The rear wheel brake must be readjusted (see Section 8.13.).
