    I have an 05 FXD that runs fine at low RPM but as soon as you hit about 3500 RPM it starts to break up. It is fuel injected. I checked the coil and wires and they are showing the correct readings for ohms. I have changed the plugs and checked for intake leaks. Does anyone have any idea what may be causing this? I have ordered the diagnostic manuals but didnt know if someone on here had run into this problem. Any help would be greatly appreciated. Thank you, James.

    What mods have you done to the bike. What are you using for fuel enrichment (PC,TFI,SE Tuner etc). Perform a WOW test and see if you have any stored/historical codes.

    Use this to check for diagnostic trouble codes.
