Can someone tell me what the needles are set at on an 05 stock raptor? Also has anyone ever put a HMF slip on exhaust on a raptor with a K&N pro flow kit with the lid off? I cant get mine to run right and I am thinking about taking it back to stock so it will at least run good. Iv'e tried about 12 different combinations of jetting, air fuel mixture, and needle movement and I cant seem to get it dialed in right? I cant remember what the needle was on when I started 1 or 2? I ride at 2200ft if you have any sugestions. thankx rotty150
