    Hey Guys, I need some help with my 2010 T100 Bonneville (fuel injected). It runs perfectly until the engine gets hot when running at highway speeds for 10 minutes or more, then it starts to run extremely rough, miss-firing, loosing power and occasionally back-firing. Same story every time I take it out, runs fine until it warms up. Anyone with some clues what may be causing this would be greatly appreciated. Cheers

    The first thing that comes to mind is you may be running lean.
    If you did any mods like a different exhaust without tuning the ECM that could be the problem.
