Since I have it apart I'm baking the crankcase, cambox, and front housing to get the bearings out so they can be measured. The liner was stuck anyway, so I figured it would be a good time to heat it up and get it out along with the bearings. For peace of mind's sake, I'll replace the bearings. .. I do not believe they are bad yet, but peace of mind is cheap. The ring gap is .003-.004" and looks to be in good shape so for now I'll leave it in. I'll get a spare though. This engine has very little time on it.
