I have an '07 250 Bayou that I got for my wife. We're at 7000ft so I got a DynoJet kit for it as it ran way to rich. Followed all the instructions for the hi altitude and I notice when I ride it and get up to full throttle that I get a pop when I let off the throttle. Otherwise, it's running very strong. They suggested the needle clip be in the top spot. I lowered the needle clip one spot to richen the mid throttle (figuring that was the problem) and I'm still getting some pop though not as bad. Should I go down 1 more clip? Could the DynoJet guys be that far off? Or am I working the wrong circuit? Oh yea, the DynoJet guide states the settings for hi altitude as above 5500ft.
