\r\n \r\n Your stock ecu, should make adjustments in your air fuel ratio up to a 10% change. I have never heard of a reset for stock ecu\'s, I could be wrong though. If you just have exhaust and maybe an air filter, you should be fine, worst ive ever seen was a bike running slightly lean, but it had more mods than just a pipe... download the service manual, tons of links around here to get one...\r\n
