My buddies had this bike a while. I put the gytr ais kit on and leo vince pipe. Its running a #50 pj and #175 main. Were having problems with it backfiring constantly and the pip glows red within in seconds if held at half throttle. It melted the bottom of the airbox and its a half inch or so away. I'm thinking of jetting it. If its too rich could this cause it? I was thinking lean but reading your guys jetting recommendations I thought 175 was too rich. Any help/recommendations is appreciated.
