Soooo!

I tried a couple of different search phrases and most everything that came back was related to intake leaks or exhaust leaks. This post is to try and get more specific responses or possible links to similure questions and answers.

Here's the deal. My 2013 FLHTRXSE2 (RoadGlide Custom 110 Screaming Eagle) backfires thru the intake on occaision when rolling into the throttle from idle, it sometimes does this when shifting into second gear but mostly when starting from a stop light. Harley has re-flashed with the latest updated ECM MAP. The bike is 100% Factory Stock and has done this from day one, over 5K on the bike and still doing it.

Looking for ideas that don't void warranty.

Try another dealer, something's wrong, and you have a warranty to take care of it.

Back fire through the throttle body is normally caused by a lean condition.....if it where me I would look for a GOOD tune up.

my 2013 RG did the same thing & I got the same run around from dealer, when I put a pipe on it and had it tuned no more problem. it was money well spent imho.

Sure, but you shouldn't have had to do that.  A stock bike doesn't backfire out of the intake as a matter of course.  If it's doing that, there's a problem.

I know I shouldn't have to fix a new bike with my money, but I was gona install the pipe any how. my dealer made me a good deal ,the se race tuner & dyno time was under 500 bucks and it made 93 hp 118 tq....a lot more fun to in that condition too.

Can't argue with you about the stock tune versus dyno tune deal, but if you look at the original post you will notice that he wants answers that don't affect warranty.  Anything other than the Harley approved stock calibration won't meet his requirement.

The bike should not stumble, hiccup, stall, or backfire even with the stock tune.  If it does then Harley owes him a fix.  If the dealer can't handle it, I'd recommend the OP call Harley direct and insist on a resolution to the problem.  It may be a waste of time, considering Harley's usual responses to such complaints, but I'd still get it on record in case that backfire becomes a stall and I got run over out on the highway because of that defect.  Then I'd get a tuning solution that would let me put the bike back to stock whenever I wanted to do so (NOT the SEPST) so a dealer or Harley couldn't screw me around on warranty down the road, and then fix the problem myself with a good tune.
