Alright i have the hmf full system and just installed the k & n pro flow kit. I am in maine about 550 above sea level. Well I started it up right after i put the pro flow kit on. And after a bit of warming up. I would touch the throttle and blue flames would shoot out the exhaust. I am running a lil rich. Right now my jetting is 175 mj,48pj, and 4clip. Do you think i should go down to a 45 pj?? or down a main jet....whats the deal??
