need to pick the brains of the pro's. I have a 03 FLSTS, I've installed screaming ignition,dual exhaust,s&s 570 easy start cam,600 lift valve springs, 10.5 to 1 pistons,milled heads .050.oil cooler and modified the existing carb,(42mm CV). I know I need more air flow, the question is what size carb venturi in your opinion would I need. thanks for any input.
