I am sorry if this is a repeat question, but I have never gottin a straight answer. Our speedometers are off by 2-5 miles an hour at different speeds. I want to know why HD has done this and how we can fix it. WHAT'S WRONG WITH HAVING THINGS RIGHT? We all have spent big bucks on our bikes, and love them. I wouldn't trade mind for any other brand. So, if the speedometer can not be fixed, can a taller tire be put on or a smaller rear sprocket. Dakota digital stated that if we put there product on it would not allow our cruise controls to work. Any idea guy on how to fix this.
