Default need help
I have a 2004 ultra I am having a problem with it misfiring. It is fine at idle and at full throttle but when it is in 4th or 5 th and running at around 1500 rpm it back fires and cuts back. The bike clears up once it gets passed 2500 rpm. Can somebody please give me some thoughts. It has been at the Harley dealer for two weeks and they have not got a clue what is causing it.

Default misfires
1) Check for exhaust leaks
2) Check for intake leaks first
good luck, then get it on the computer and get it up to that rpm and see what the screen reads.

If you are serious and not just trolling..(which I think you might be)....Downshift your freaking bike... you should not be under any kind of load at 1500 RPM in 4th or 5th gear...
