My 883 custom bogs and back fires after warm-up, it idles great thou. I think it's the ignition module---does anyone have suggestions.

What Do You Mean By Bogs Down, Then Idles Good After Warm Up? My O3" Did Simular Things After I Changed Pipes. Try Tighting Your Flanges On The Pipes. That Stoped My Back Fireing And Bogging Befor Warm Up.

Yepper, as sportsterboy says, if its under warranty, let the moco deal with it, if not, buy the service manual. I doubt it’s the ignition, what year is it?
