[QUOTE="biglou, post: 127026"] The KTM's are jetted extremely rich when stock. It's not the same as when I do 1/2 lap and it dies because I forgot to turn the petcock on, and this happens more often than I'd like to admit! There is no missing/sputtering when I just let the throttle go. It's very similar to when you hit the kill switch. When I'm coming into a corner, or a similar situation where the motor is "freewheeling", it is still running/firing (corrrect terminology?). Doesn't the vacuum created by this continue to pull fuel into the cylinder to perpetuate this running condition? If the clutch is pulled in, THEN it will fall off and die if the throttle isn't blipped. Isn't the physical position of the slide off of it's end of travel, not the pilot jet, what dictates the idle speed? Inquiring minds want to know! :think Any experts on the theory of operation of these circuits? [/QUOTE]
