CDN,Im starting to think something is wrong in the design of the kehin.I think there are different slides available with a different cut around the air passage for the bottom of the slide?Or maybe the case induction gas gas design ports are to radical for a good idle?I dislike anything that dosnt idle it gets me pissed.Those trials bikes they make must idle or those guys probibly wouldnt ride them -right?My 01 ec250 is almost right but it still screws up and peeders out here and there.It likes to be super low or a tad to high.If i can get my hands on a MIC im going to try it unless i hear of a positive fix
