[QUOTE="Rhodester, post: 824863, member: 42241"] I'm intimately acquainted with your problem! The quickest fix to try is a richer main. Go fat enough and the hesitation will go away...but, you MAY end up too rich on top (I did). Also try raising the needle 1 clip position (lower the clip). I had the best results going with a longer and richer L1 (straight section) on the needle and running it high (low clip position, 4 or usually 5) and keeping the main jet pretty close to where it should be. Longer straight section means a Cxx or Dxx needle instead of the stock Bxx taper. I'm currently running a 42 pilot, AS at 1 1/4 out, and a DEJ/5 needle. I vary between a 150 main (6000' and 70 degrees) and a 155 main (2500' and 60 degrees). My off idle hesitation was also sensitive to the Air Screw. 1/4 of a turn (leaner) can bring my hesitation back. I went through 9 main jets, 5 pilot jets, 3 slide cuts (I currently run a 7), 13 needles and a years worth of testing and logging time to figure this hesitation situation all out on my bike. All that being said maybe I should have put the air box lid back on and saved myself allot of trouble :-). [/QUOTE]
