Bike is in great shape. Alot of upgrades. Only like 80-90 pounds on each side though. I'm not sure on the bore size, I'm going to have to measure that when I pull it apart. Guessing that it has the stock bore, or maybe slightly larger than stock, can I just order that size top end kit with pistons, rings, gaskets, etc.? I think I read somewhere that pistons for a stroker crank are different than the normal ones, in which case, could I just order a set of rings and gaskets and get some decent compression?
