Yes I have the stalling problem as I stop also, and mine backfires more than I would like to hear too, I don´t mind the small backfires cause harleys do it too but the load ones I feel aren´t right, I get the same stupid answers from the service manager, I think my throttle sticking ,backfiring, and stalling are going to be all inter-related when the fix is done, they just don´t know the answer as of yet, but all of it is intermittent, and as a mechanic myself those are the worse to locate, but I told them to just start changing something instead of the lip service I have been getting, good luck, bikes got alost 5,000 miles now
