Can anyone give me the cylinder to piston clearances on a XR80 honda dirt bike?I need the max I dont want to have to bore this old bike out it is .0025 after I honed the bad spots out.Does anyone think it will run ok long enough for the boy to learn a clutch if I just ring it.It would run before but wouldnt idle checked comp and it was only 60lbs oiled the cyl and rechecked at 120lbs.Any advice is welcomed.
