Dear needle heads, I have tried going through the old posts and find the right jetting for my bike but every time I do I get a headache from all the nygcyuerbc34726736 if ya know what I mean. Yes, I am asking for the easy out so if you could help me out I would really appreciate it. I have a 2000 WR400, throttle stop trimmed, yz timing, pro circuit exhaust and all of the jetting is stock. I live at sealevel and am looking for year round jetting if possible. I do know that I need to richen it, I think, and the studder/hiccup is from the acc. pump, right? All info on needle-clip-jets-airbox-airscrew is very appreciated. Thank you!!!!!
