I bought my bike used. I had a tire put on it on 4/23/09 and the technician printed me out some information on my bike. It has a bunch of codes and I have no idea what they mean. I have been having a problem with loss of power and blue flames shooting out while I'm driving at night. I was thinking about getting a power commander. Well the sheet is a print out from "Harley Davidson Digital Technician II". It says ECM EFI/Ignition race tuned Yes. Now the guy said that he believes another code on the sheet is a harley race tuner code. I honestly have no idea. I'm just wandering what kind of advice I could get and how I should go about figuring out what I've even got on the bike. Any and all information pertaining to this would be greatly appreciated and thank you very much for your time and effort!
