    I have a 96 1200c with a S&S super E carb , bored .040 . screaming eagle ignition , Vance & Hines straight shots , and a cam upgrade , although I don't know the size . Since I bought this bike , I've had problems with it kicking back on start up. I tried to tune it out but it was still there . I checked for intake leaks , still there . Well I'm happy to say that I finally found the problem. I replaced the battery that was in the bike ( walmart special ) with an AGM style 300 C.C.A. battery and no more problems . SO if anyone else out there is fighting these same symptoms maybe this will help you .

    A low output battery or smaller than needed will surely cause the problem you were having.

    You may also want to remove any carbon from the cylinders which would also help. The carbon raises the compression ration and can also cause the kick back you were having. There's no downside to doing this procedure.

    Good deal!

    It's best if you turn the exhaust towards a wall. You can see all the carbon that comes out then.

    Plus with the AGM (glass mat) style batteries there is no drain tube to leak out . Slower rate of discharge , can be mounted at an angle if necessary , though I wouldn't recommend it , Well worth a little more dough
