I purchased a 2004 vegas this month and love it so far but it has a pretty good vibration to it. as far as I know, the bike is stock. starting around 2500 rpm there is a pretty good vibration that gets worse as the rpm increase. I have ran it around 4000 rpm and pulled the clutch in and the vibration immediately goes away. normally I would set the valve clearance and rebuild and sync the carbs but ive never had a fuel injected bike so im not sure where to start.
