QJ250-3 Motorcycle Valve Clearance Adjustment

Generally, the intake and exhaust are 0.0 1 to 0.02 larger than the intake valve, but the parameters of engine intake and exhaust above 125CC are all 0.0120.02mm..

First measure with a feeler gauge. If the standard is not adjusted, select feeler gauges with different thicknesses according to the parameters specified by their respective models. For example, if the specified value is 0. 12mm, two feelers, 0. 1 and 0.02, are selected to add up to 0. 12. Plug it in and pull it back and forth, using 0. 1+0. Hope to adopt
