Hello all, I have an 05 wr450f. I had the pro-moto billet insert, ais removal kit and jetted to the paperwork that came with the kit. I ride from 700' to 7000', temperatures from 35 to 110 degrees. It seemed to be jetted perfect. I just put a stock exhaust off a 03 YZ450 on it and noticed back "FIRE" on deceleration. What jetting changes should I be looking at. I believe I am set with a 48 pilot and in the 4th position on the clip. Any help would be greatly appreciated.
