Does the 2009 R6s have an Ex-Up valve on it? I know it does not have an O2 sensor in the exhaust. I recently had a PCV put on and dyno tuned it. Afterwards I was getting and itntermittent check engine light when on the expressway. My battery did die on me while i was reading the diagnostic codes, so I replaced it with a new battery. The mechanic did put i back on the Dyno and checked the map, he said that was fine and he couldnt get the check engine light to pull. He brought it to 120 MPh on the Dyno but no light.... Figures LOL. The mechanic is good, he know his stuff so i'm not worried about that. I was just wondering if my bike had that part as sometimes it sticks on some bikes.
