Sounds like the previous owner didn't get the cpu remapped, Take it to a Harley dealer and have him check the exhaust mapping on the cpu, Shouldn't cost much or if you want get them to fully service it so that way you will know were your at with it and will have a reference point to start with or service and maintenance reasons (and re-sale value) Hope this helps

Is my motorcycle fuel injected or carburetor? when trying to start my bike at a cold start it takes awhile to start. it sometimes back fires and makes a wierd sound.


irt is carbureted and all bikes dont like to be cold sharted you need to wait 3 min to let it warm up before you rev or leave on it. do you live in a humid/colder climate because that can have alot to do with the early morning and cold starts

You cannot, unless you have the Screamin Eagle Race Tuner (SERT) or you take it to the dealer (at about $80/hr.) Sorry I don't have better news, hope this helps.
