I have a 97 Heritage softail and its got a screamin eagle selectable race module, So I was wondering if someone could tell me what the little switches on the bottom due? Or what they are for and adjustments? I do have a problem with it backfire's threw carb when I hit the throttle at stops but runs great going down the road and some black smoke from tailpipes when it backfires from carb.... Could ya help me out?
