Question about 2003 Triumph Speedmaster
2003 speedmaster is running rough at low rmp. It backfires and lolups at lower rpm. I can get up to a higher rpm and seems to run smooth. Have drained the gas tank and put a small amount of carb cleaner, put new gas in hi octane and rode a few miles, but still does the same thing.
You did not say whether or not this was a carburater engine but from the sound of it one of your jets may be sticking, a good cleaning of the jets will most likely fix the problem, the likely cause is a small build up or piece of debris on the jet.

Make sure that the pulse coil that sits inside the engine is the right gap from the flywheel, although you can't change the ignition timing you can change the gap between the pulser coil and flywheel. Triumph changed the specs on the Bonneville and it has 2 different settings. depending on the year it was made, which way the wind was blowing and what man assembled the bike.
