Well, It's amazing what the correct parts will do. Got the GRiSO up and running with the correct "A" roller kit installed. No leaks, no runs, no errors. As you may recall, my first attempt with the wrong kit resulted in my bike doing a fine impression of the Exxon Valdez. I have yet to re-set the TPS, but the bike seems to be running fine. Pulls strong with no popping on decel. I do have a question. What model ECU does the 2012 use? The reason I ask is, I have the TecnoResearch Centurion M software loaded on my laptop and believe it will work to re-set the TPS, but I need to know what series ECU to select on the menu.
