I recently had my cylinder bored to .010". I purchased a new wiseco piston kit. I rebuilt my carb and installed oil block kit and tors delete. Upon assembly of engine I install a new fixed stator. Quad started on third kick while being choked. After letting I'd run for a good while I pulled in clutch lever and put into first gear. Quad lunged foward and stalled. Anybody have any idea on what's wrong?
