Oh, and the cause...

PO said he was riding along at 50 and heard a death rattle. Bike would crank and make a horrible noise. Then at some point the starter would click, and nothing moved. When i tore into it the piston was at TDC with a chunk of valve seat pinned between the piston and head, preventing full rotation.

The guy at the head shop assumes unadjusted exhaust valves overheating, which i believe. There was a bit of an exhaust leak between the cylinder head and head, which makes me think the thing was running with wicked tight/overheating exhaust valves for a bit before detonation.
