Hi All, really hoping someone can chime in with some advice, I have an 09 FE 570 that has been converted to a snow bike, so lots of full throttle running. In an attempt to get more power I have done the seat mod and added an Akro slip on. Will the stock fuel map be ok? I know there is an O2 sensor in the exhaust, is the system capable of adjusting fuel based on it's readings? If not why does it have an O2 sensor? Would love to hear from someone who has some first hand experience, thanks, Derek
