How do you adjust haojue 125 valve clearance?

To adjust the valve clearance on a Haojue 125, first, ensure the engine is cool and disconnect the battery. Remove the valve cover to access the valves, then rotate the engine to set it at top dead center (TDC) on the compression stroke for the cylinder you are adjusting. Use a feeler gauge to measure the clearance between the valve stem and rocker arm; adjust the clearance by loosening the lock nut and turning the adjusting screw until the desired clearance is achieved. Finally, reassemble the components and check the clearance once more to ensure it's within specifications.
