What controls 1/2 to 3/4? Jetting

[01bansheefox]

I seem a have everything dialed in pretty good, plugs a tad lean on the wot end but if I cruise at half throttle and just slowly accelerate it hesitates, but if I open it up you better hang on!, what's something to look at?

needles control jetting. if you're a tad lean at wot try bumping the mains up a size or 2 and see if the hesitation goes away.

maybe lean. bump up the mains a size or two. since u say ur lean at wot u probably are lean at 1/2-3/4 also. u could raise the needle to see if that helps. then if it does, but not enough go up on main jet.

I thought hesitation was from being to rich? Do you mean move the clip on needle? I'm at 300 main now, I'm gonna jump to a 320.

hesitation can be lean or rich. rich hesitation last longer than lean.
