    I have a 2001 1200 sportster, When the engine gets to normal running temp the littlest of throttle and the engine starts to back fire and the engine stalls out. I have changed the plugs, wires, coil and new battery, any other ideas?

    A buddy of mine had a similar problem with his 05 1200c and he took the heads apart to find he had an intake leak that caused a carbon build up.

    My fxrs had that problem turned out to be an ignition module problem. But I didn't get it fixed until the thing just up and quit the one day.

    I had the same problem and it was my regulator. Had to get a new one. Thank God it wasn't the stater plug.
