Adjustment of system of idling is carried out on the heated-up engine. To warm up, it is enough to ride a motorcycle for 10 minutes. The adjustment knob is located under the fuel tank, between the carburetors of the second and third cylinders.
The idle speed is controlled by a tachometer and should be 1200±100 min-1 on a warm engine. Turning the adjusting knob clockwise decreases the speed, counterclockwise increases it.
