How to adjust the valve Quan Song of Cg 125 motorcycle injector?

1. When the timing is good, adjust the valve clearance again. If you have no experience, you can buy a feeler gauge and adjust it.

Remember, don't start the engine until it is transferred back.

3. Remove the two small observation covers on the left cover. The way to align the timing is to turn the crankshaft until the T mark can be seen from the position of the observation cover, and then remove the cylinder head, which is the valve adjusting bolt.

First, open the two maintenance covers on the left side of the crankcase, rotate the magneto rotor counterclockwise with a socket wrench, and the sign of piston top dead center appears from the upper observation hole. At this time, there should be a gap between lifting the two adjusting screws up and down by hand, and then adjusting the valve clearance by hand. The method is to loosen the lock nut and turn the screw, and then tighten the lock nut.

What matters is the gap value: most manufacturers' instructions indicate 0.08 mm (8 lines). But this is not the best value, and the best value should be 0.02 mm (2 wires).
