Big Drag, don't take offense! Lots of Folks read things on this forum or ask absolutely silly questions and then admit they don't even have a bike or their ride is a 49cc pedal moped or someone contemplating his or her first bike, a 200HP superbike--believe me, we have seen it all BUT we always help, when we can.
I built some big bore HD bikes, all aftermarket and I also did big bore kits for single cylinder, 4 stroke desert, Baja and track bikes and it gets fairly technical as in Deck height, Piston and valve clearance interference, compression ratio, Jetting, exhaust flow, on and on, so for the average person, it can be daunting. If that piston at either top or bottom dead center even slightly touches the CASE or the Crankshaft, or the Cylinder head, the fun is over and the real expense begins!
Have fun and let us know how it all turns out!
