Re: 71' CB500 monoshock with no name.
That was my exact thought Teazer. I've called around and am waiting on 2 quotes for having a shop do 3 angle valve seat cutting and having them do it. Prices they showed on the net were about $160 to do that (if I read that correctly) which I don't see as TOO bad. I also bought all the stuff to do a quick lapping, but read all the horror stories on here about ruining valves etc. I know not to use a drill, and to do it slowly by hand while picking it up several times ----neat video on here somewhere. Anyways, thanks for the info, it confirms my lack of knowledge in headwork! Will a quick lap like that ruin the valves? Or do these not really have coatings like the new ones?
