    Hello, I have an '05 dyna super glide and put in the kit with the #48 idle, #195 main and the EZ just mixture needle screw. I also have the SE a/c on the bike and can not get it stumble as I seat the mixture screw. Do I have the wrong idle and main combination? The bike also backfires when I turn it off, can I get a little help?

    You didn't mention if you have an exhaust that is more open than stock but I suspect the jetting may be on the rich side. I would start with the #46 pilot and #190 main and tune up from there. Twin Cams are known to not give as much of a stumble when adusting the mixture screw in since their ignition tends to compensate. An accumulation of fuel as the engine shuts off can cause a backfire.
