I have a 2009 Screamin Eagle Road Glide with Electronic throttle control. When I start the bike most of the time, I have no throttle. Other times it revs up to about 4,000 rpm then slowly goes back to about 1300 rpm. At least then I have a throttle. I have set an appointment with Harley to have the bike looked at but this is the second time it has happened in 3 weeks. Has anyone else had this experience or does anyone know what may be the cause of this?
