Hello; Mike here. Does anybody know which DFI error codes affect the way the bike runs, and which ones do not? I would love to remove the exhaust servo controller, the complete throttle body secondary throttle valves controller, and the air injection solenoid valve, but I know that I will get warning codes for these. Does it affect the way the bike runs? Is the only problem the red flashing light? Do most people just tape over the light, or remove the bulb? Any help is appreciated. thanks. Mike.
