Bought my bike used, 02a. Came with SE air filter, and looked like the pipes had been changed and later changed back. I'm guessing that it had the ECM flashed for the pipe change. I put on a PC3, and tried to run it on the stock map, and it ran poorly and stalled out. Convinced me even more the fuel curve had been adjusted. Going to the dealer on Monday to have the ECM read to see if it has any flash on it. If it does, is it possible to reflash it back to stock? Service said over the phone that the computer gives them some warning screen about doing it.
