It was my understanding when I installed these on mine that these are more for a tip over than anything. I could be wrong though. There was a few pics of a bike floating around here quite awhile ago that showed the the slider snapping off and going right into the side of the fairing that had been involved in a low side. I'll see if I can dig up the thread.
EDIT: Found the thread with the pics. Not much but best I can do for ya. http://www.vfrdiscussion.com/forum/index.php/topic/54276-fairing-slider-options/page__hl__snapped
You probably have a USA model. (just guessing) I have an 07 and looked through the Owner's Manual just a few minutes ago and it does not list a way to change it. Only shows MPH and KPH changes. Says F for USA, C for Canada. So my guess is you can't. Try searching the forums. Might find a better answer in there for ya.
I always love to see someone take a bike and really make it their own. Who wants to be the same right? BIG :beer: for you for all your hard work. Love the pics!!!
