My bike backfires when I shut the engine off. The AIS is removed with all free mods. 48 pilot, 04 needle 4th clip. Runs great. Any ideas?? :thumbsup:

Well usually a backfire is extra air igniting in the pipe (someone catch me if im wrong on this one) so maybe your running a little rich? That would be my first guess. But there are others more experienced than I that would let you know for sure. Im a little curious as to the 100% reasoning/truth behind it myself.

i think you are running a little rich.

I had the same problem , I was a little to rich lean it out a bit. good luck... :thumbsup:

I turned the fuel screw in a 1/4 turn and it has solved the problem. Thanks for the feedback. :thumbsup:
