Had my Busa four years now, decided to get it bored to 1400, HC pistons, gas flowed head, HD starter gear, lock up clutch, yoshi cams, yoshi RS3 system, billet cam chain tensioner,12mm head studs, HI vol oil pump gear + loads of other bits
genuine 200 + mph bike, 192 bhp with 120 lbs of torque.
more than happy with it.
