[QUOTE="not2shabby, post: 1010430, member: 18615"] Ok, since I have the bottom end of the original motor that dropped a valve, I split the cases to check it out. There was a little bit of crap in there from the piston so I sprayed the hell out of it with WD40 and all the bearings seem ok. Now I just have to get the tranny back in the way it was and seal it back up. Last night I pulled the top end off the knocker and hmmm, that piston looks bigger than the other one that got demolished. Hey, it's 86mm and stock is only 79. The piston hardly has any carbon on the crown and the rings are clean as can be. Evidently someone put a big bore kit in it and then it probably sheared the rotor key and they let it sit. Guess I don't need a new piston/rings set after all. The bore looked really good too, I'll just hit it with a hone [/QUOTE]
