All I have is a aggresive dune port, fmf fattys and silencers, advance timing, boyesen reeds adn some other stuff I cant think of right now. I ran the 20x10x10 10 paddles on a stock 00 with only fmf pipes and silencers and boyesen reeds and was beatin a crap load of built bikes. Right now I have 8 paddles sand sharks but want more bite and more of a holeshot get to much tire spin.
