Thought I would throw this out there in case people don't know. There is a soft(normal riding) and a performance mode. Under the front nose piece is a small flat electrical plug with 2 wires. If this is plugged in it is in the soft mode. This is how it comes from the factory. If you unplug it, then it is in performance mode. I am not sure how it is doing this for sure. I am assuming the timing curve is being changed. If anyone knows how would be interested in knowing.
