Good carburetion is the key of engine performance. 

Keep the original condition of the carburetor, as set 

in the factory. Pay attention to these two items for 

adjustment: throttle cable clearance and idling.

IDLE SPEED

1. Keep the vehicle on flat surface. 

2.Start the engine and warm up the engine for sever-

al  minutes.

3. Clip the digital Tachometer to the spark plug cable.

4. Adjust the idle screw and  keep the revolution of 

engine stable.

IDLING ADJUSTMENT

The valve clearance changes with use, resulting in 

improper air-fuel mixture and/or engine noise. To 

prevent this from occurring, the valve clearance must 

be adjusted by a dealer at the intervals specified in 

the periodic maintenance and lubrication chart.

The engine is required to be in normal operating 

temperature for accurate idling adjustment.
