Yes it will be faster that a "Vito's" 240 kit. My logic is buy the 240 kit, carb, reeds, and good pide. Run it like that if you still want to make it faster than just get it ported. If you just port your cylinder and want to go faster your kinda stuck. I would never buy the Vito's 240 it anyway. It makes more sense to press a la 240 sleeve in the stock cylinder. Much cheaper.
