Went out on a ride yesterday later in the day. I had been riding for approx 45min. I came to a stop at a traffic light. It was then and there at the stop light, I noticed my RPM needle was at Zero with the motor running. When I revved the bike , the needle would go up and return to zero with the release of the throttle lever. At the next traffic light , the gauge was operating normal. Has this evere happend to anybody else? If so, what could have caused this.:confused
