what jet do i need with a whitebros pipe?

[polcat1p]

Im thinking of get a white bros titanium full system, but dont know what size jet to run? other than the pipe, my motor is stock. I was also thinking on removing my choke at the same time.
Thanks Chad

its kinda hard to just pick a jet and call it the right one, jetting is trial and error. Talk to whitebrothers to see what they have to say.
