I'll leave the diagnosis to those with more Buell specific experience since I'm new to Buells and just beginning to learn them myself. But, with that said, for many bikes, what you describe is often the symptom of a bad ignition coil or ignition module/CDI unit. | ||

Start simple - any brown spots on plug wires? That indicates an arc to ground (a short). Read your plugs. Should be tan. If one is blacker than the other...that's the one that's acting up. Change it, and its wire, to start. Check all your connections. Could be coil. Could be ignition pickup (located on the end of a cam, under the round cover on the right lower side of the engine). Could be ignition box. Be methodical, patient, and follow a pattern. Check one thing at a time. | ||

Pay close attention to the coil and the ends that push in(plug wires)look for black soot.I had a coil go bad and it eat the inside of the coil out where the plug wires go.Was a stock coil.Ran good at speed and would only occasionally fall off on one cyl. |
