Now that I have got my K77 registered (mechanically it's an Ace), need to think about trying to make it go properly: My Ace has 'sports' exhaust (which does make a lot of noise but does not seem to make it go faster), I am looking at the 150cc kit but what can I really expect in performance? Does anyone know what difference the gas flowed head makes? Is there an exhaust out there that actually allows the engine to breathe without scaring the animals too much?
