I have recently aquired an older model banshee (i think 90) that needed a new top and bottom end. It has 68 mm pistons and stock stroke. when its running, the pipe jumps down and flames are visible. It smoked alot and has no top end. It wont rev up and the pipe continues to pop. I put new reeds and tried re jetting the carbs. I went from 200 mains down to 180, but still does same(not smoking as much though). The stator is stock and i am out of ideas. Oh, i forgot to mention that i rounded off the sleeve since it was square for better flow. The sleeve was so large that it was into transfer ports so figured it might do it some good.Please help. any info will be greatly appreciated.
