Extended data:

There are two screws on the engine of motorcycle, one is to adjust the idle speed and the other is to adjust the mixture. The screw for adjusting the idle speed is located at the cable damper on the carburetor side, and the position is obvious. The screw for mixing gas is located at the longest place on the left side of the engine at the top cable.

Idle oil holes and idle air holes are set in the idle oil circuit to control the oil quantity and foam the fuel. Idle speed can be adjusted by idle speed screw.

Because the mixture required for idling is small and thick, it is sensitive to the running condition of the engine. In order to realize the idle state with stability and minimum speed, it is necessary to adjust the fuel quantity control and the minimum throttle opening.
