Valve clearances

I bought a YS 140 DZ and want to readjust valves before running it (the engine has been used a little).

I can hear there is some play when I turn the engine over and think it is valves that are not adjusted.

Any recommendations would be appreciated.

VALVE CLEARANCE

Most 4-stroke engines make some clicking sounds when turned over. It is probably the cam and gear area making the sound. The clearance in the valves is so small that you won't hear it. For setting the valve clearance, a setting of 0.0015-0.004 inches is normally used. I set all of mine at 0.003 inches.
