Jetting and air/fuel screw settings for a raptor.

I got a stock 2004 LE Raptor runs great but it was running lean from stock. The air fuel screws are adjusted incorrectly. I was wanting to put a K&N on it also with a pre charger. So I was wanting to know what jets should I have, how many turns for the air/fuel screw, or if I need to do anything else. I was also thinking about getting an exhaust later but I was looking at the LTE Dual Exhaust, Big Gun, or HMF.

I have a 2001 raptor, that i installed a full FMF exhaust. I tried a lot of trial and error on the jetting,with no real luck, even with a lot of help from people in this forum. Although i really appreciated this help,,i was getting nowhere quick. I finally bought a Dynojet stage 2 kit,,and let me tell ya,,i should have done that a long time ago. She runs PERFECT. Do yourself a favor, and go ahead and buy the correct kit for your application. Also i would like to thank all the guys who gave me advice in the past.
