my banshee has dmc pipes, delta v force reed system, k&ns, 60 over wiesco pistons, and 34 mm keihin flat slides with 215 mains. it runs great, it hauls ass up to half throttle, but if I twist it all the way open, it doesnt increase power at all.. it still runs great, but its like that extra 50% of the carb opening doesnt add any power.. it doesnt bog or act like its starving for fuel,, but it doesnt add any extra kick.. didnt know if maybe with my setup, that perhaps its starving for more air.. like maybe it needs ported or something.. maybe the stock intake ports arent big enough..
