I got my kdx running great but layed it down on the trails.too fast in greasy sloppy muddy conditions.but anyhoo I layed it down and cracked the dyno port header.I went ahead and ordered the pro circuit platinum pipe for bling factor and from what I've read pretty good.problem is I can't find much info on the dyno port and I don't know if ill need to rejet.as of right now I'm running the pwk35mm carb with a CGL needle 2nd clip from bottom and a 45/158 jetting and its running great.is anyone familiar with these motors and pipes?which is a better pipe?and will I need to rejet?
