ok here is the deal I have an 05 banshee with the following mods. T6 pipes, shaved head, +4 timing, taper bored carbs, k+n pods, boysen rad valve reeds. It ran really good till I overheated it. I am going to tear the motor down and do the following, agressive dune port from kevin at herr juggs 4mm stroker crank and noss head. I know my pipes are not the preferred for this set-up but I am going to try them before I get something different if not just out of curiosity. also I wanted to know what size and brand of carb is best for this set-up. I was looking at some keihin 30mm carbs but think maybe 33s? or should I just give the stockers a chance? I would like to retain some low end
