Hi, I have a 2002 Harley Road King Classic with 60,000 on it. Yesterday when driving about 300 miles, the check engine light would come on when maintaining 60 mph or greater. When slowing down the light would go out and stay out until I accelerated up to 60 again. It would not go on unless I maintained the greater speed for 5 to 10 minutes or so. Bike ran fine the entire 300 miles.
