I installed blue needle clip 4, rest of carb stock. Took bike out and fouled plug in 5 minutes. Temp was maybe high 70's, but humid, ride in michigan around 1000ft. So I'm guessing that I need to try the red needle clip 4. Could there be another problem why I am fouling plugs. I think I might try to put the eln clip #3 needle back in to see if it still fouls so quick. Tctrailrider if your out there, I can't understand if setup works for you and your in Traverse City area, and it won't work for me and I'm in Gaylord. Thats why I'm starting to wonder if there's something else going on. (My air jets were not clogged from the air cleaner foam oil).
