Adjust the carburetors for in-step operation of engine cylinders as follows:
- Start the engine and set a speed of 1,500 to 1,800 min;
- By cutting off alternately each cylinder determine by
ear whether both cylinders ensure the
same speed. Adjust the engine speed to be the same to each cylinder.
Turning in or off the cable sheath guides altering the throttle valves lift performs the adjustment
of carburetors.
After completing the adjustment, lock the control cable sheath guides.
With the throttle valves fully lowered there should be a clearance within 2
-
3 mm between the
cable sheaths and the sheath guides, almost; the same for the right- and left-hand carburetors.
Having adjusted the carburetors for in-step operation, lock the guides in place.
Adjustment of the mixture composition under partial load duties is performed by shifting of the
throttle-metering needle in relation to the lath and is described in detail in the motorcycle service
Manual.
In the course of running-in, check to reveal:
- Oil leaks in the joints;
- Abnormal noises;
- Local heating of parts.
- The engine performance at different speeds and loads.
Remedy all the detected troubles at once.
