I'm in need of some tech help on my 04 XB 12R. no trouble codes come up but engine will start surging spuraticly at any RPM any speed any gear. Changed coil,plugs reset TPS and AFM on digital tech at HD service dept. the tech can't find the trouble. Any help would be great trouble stared around 20,000 mile service. check fuel tank vent to make sure its not vapor locking don't know what to try next. mods were install from day race ecm k&n air filter and buell race muffler. just trying to give all info i can. |
