2010 Harley Davidson Softail - I had a bad tank of gas in my bike. Drained the tank and accidentally put in diesel. Immediately drained tank. Added fresh tank of gasoline. Bike starts and will idle but when you rev the engine it dies. What could be causing this? If you change the battery does the Dynajet Commander V tuner lose its memory? How do you reload the map to the tuner? How do you change the fuel pump and where are the fuel filters located on the bike/?
