Everyone who replied,
Thanks for all the advice and help, but now I've got a huge problem. When we had the work done (by the most reputed shop in jacksonville), they forgot to machine the the dome where the spark is created, so the larger piston was BEATING on the the dome, since it (the flange that starts the curve towards the top where the spark plug is) wasn't made larger for the larger piston. The piston repeatedly beat itself off the top of the dome, smashing the electrode into the spark plug, loosening the connecting rod, breaking a pin valve (looks like a finger ring with pin like bearings on the sides) and sending the pieces through engine, leaving shavings everywhere, gouging the cylinder walls and the piston, and out the exhaust. God knows what happened in the crankcase, but we gave them the unsplit case, piston, and top end, along with all the pieces that came out of the pipe. My dad basically told them pay for it all, and they're going to redo everything. A trained motorcyle mechanic and machinist, dave, came over and told us exactly what happened. Even someone who has the slightest idea (if any) what they're doing when it comes to working on motorcycles can figure this out. It's not CSI. But anyway, we'll have the bike working this weekend (I'll do everything I can to have it working by friday blah blah blah please don't sue me) and I'll let you know how I fare.
thanks again,
cliff
