I am a relatively new owner of a 2006 V Star 1100 Classic. My problem is that when I first start out on a ride and the engine is cold, my speedometer reads low. When I am really doing about 50-60 mph my speedometer is reading under 30 mph. After about 10 miles it works its way up to the correct speed reading and is good for the ride, even with stops to eat or shop. Any ideas about what may be going on or where I might look?
