Re: Valve Adjustment

Forget "cams" etc. The only thing you need to determine is that the valve you are adjusting is closed.

Remove the spark plugs and rotate the engine until both valves on the cylinder you are working on, are closed.

Look into the cylinder with a light, if the piston is right there, rotate slightly to be sure it is at its all the way "up" and stop there. You can do those valves when both are closed when the piston is at the very top of the cylinder. Repeat on the other if this is a twin.

Recheck after some run time.

Take your time and be logical. You can do this.
