My dyna CDI ran GREAT before i added a snorkel and then it had a little popping when holding it at steady throttle and then i added a pipe and then it would backfire after a WOT run and let off.

Note: I've jetted every way possible that miss IS NOT going away period. A guy took his to the dyno and his a/f ratio was perfect yet the miss was still there... you're wasting your time trying to fix it with jetting and i wasted a lot of it.. i'd hate for somebody else to have to do the same.

 

Thanks everyone for all the info, now I will have to decide on which one.
