OK...I put the 13/13 carb w/ a Mallousi Red AirFilter...Polini Top Mod One exhaust.....PLUS a 43mm Polini cylinder kit, but I'm breakin it in and haven't tried to top out yet. A Beamer next to me clocked me at 37 mph...and thats not even my peak. Its goin a whole hell of a lot faster...and when ridin today i felt that rush...SMILE>>> what else can I do to my bike???????????hehehe
