My personal lash specs are .05mm intake and .07mm exhaust. You can also simply use the Zongshen valve lash spec of .07mm for both, with a check interval of 2500 miles. They will still be a bit clattery as that is just the nature of the beast with these engines, but it shouldn't sound like gnomes with hammers are on your top end opening the valves.

Makes sense. I used .002" and .003"and while close, i think those are a hair bigger than .05mm and .07mm.

You are correct. .05mm is .001968 inches, so minutely smaller than .002. .07mm is .0027559 inches, also sightly smaller.
