Thanks GrandPaulZ,

To answer your question, yes, the bike was smoking and yes, I do need four new valve guides. They definitely are worn. The manual states that the exhaust valve stems call for .3090 to .3095 inches whereas I am reading .3085 on the main stem.
I guess I was wondering if 5 thou was significant enough on valve stems? This stem wear is the only defect

I think that I will definitely change the exhaust valves. The inlet valves look like new. Where does it end? Ideally the con rod shims should be changed out as well. new wrist pins etc.I am at the limit of having to oversize.
