I have 2001 KDX 200 and it has issues idling. The initial startup is a little difficult, but not that bad. If the bike dies, I can start it right back up with no problem. If the bike is on the kickstand, which makes it lean to the left (obviously), it idles fine. I can stand it up level and/or to the right and it will die (not instantaneous, but fairly quick). I can lean it back very quickly to the left and it will start back idling if I catch it quick enough. Likewise, when I am in the woods riding and back off or engage the clutch it will die…I can release the clutch and it starts right back up (I would assume due to the momentum of the bike and not a clutch issue)
What can cause this? I have had several ideas from several people, but am hoping that someone has more insight into this. Should I change the jets? Is it a float issue? Top end need rebuilding? Please help this is very annoying to deal with in the woods!!! Below I have listed the setup of my bike.
