Some quick and inexpensive mods are; go up a a tooth on the front sprocket, good rear tires, Razrs come to mind, advance your timing with an adjustable plate, lighten your flywheel, carbon fiber reeds and port your own reed cages, or just get some V-Force. After that, get er ported, buy some CPI's, Rockets or T-5's, get bigger carbs, yada, yada, yada. Rydas' post really hit home. Once you start you cant stop. Your shee will never be fast enough, quick enough or shiny enough. Welcome to our misery.
