Need to adjust cam chain tension on an OHC 200cc engine - Page 2

So there is no need to adjust it ever??

What about the valves??

Sounds like it doesn't need adjustment. The valve adjustment is in the manual that came with the bike. Set engine to TDC, then set valve lash. I am assuming the valves are lashed with the engine cold. Of course the manual that came with my bike was for the pushrod engine, but I assume the valve lash would be the same for the OHC.

Hi All
Valve adjustment is on a cold engine at TDC, both intake and exhaust valves should be set at .002-.003 thousandths.

Thanks Bruce! Is it better to have these OHC engines closer to .003 than to .002 ? Something I remember reading about them working there way closed or something.

Hi Guys
Adjust them between .002-.003 and you'll be Ok. This goes both of these engines, Push-rod & OHC {Over Head Cam}. Valves wear and so do the seats this is why they need to be adjusted. I tighten then at a tight .003.
