When I bought my '08 I was riding it home and noticed a problem. Turned out to be missing O2 sensors. I had one from the PO
but needed to purchase one. The back cylinder's O2 sensor connects behind the right side panel. It required that I splice some wire to make it reach.
To this day, the back cylinder plugs are richer than the front and occasionally, at constant throttle, I get some stuttering at low speeds...
Wonder if it's because of the splice?????????
