I've only had my bike for about a month but it seems like I'm constantly adjusting the mirrors. The arms don't seem to be moving but the friction portion seems to keep letting the mirrors tilt down. I've even set the mirror high and by the end of a 50 mile trip they need moved up some already. I never had this issue with my old bike but I was surprised that both mirrors are doing it. Has anyone else run into this or should I talk to my dealer about it?
