Ok I have an aggresive trail port,boost bottle,+4 degree key,fmf fatties with turbine core 2 silencers,running br9es plugs, 300 main jet and stock 25 pilot jet. It is running at little shabby like when you first press the gas it kinda wants to bog down a little bit then it open up and runs good when you give it like 1/4 throttle. Anyone got any tips? Also what are the carb needles?
