Jeff, I put them on my 09 and used them off and on the last 2 seasons. The bike really looks different with the stock screen and bar ends. Like the other reader commented, you cannot see things as well, and you have to glance down versus forward with regular mirrors.
I installed them with a set of Rhino Tech bar ends that have a groove to hold the CMG lane splitter mirrors that connect to the bar end with a swivel so they can be closed in in tight areas. I have an extra set of the mirrors that I'll post up for sale, and they come with an insert to affix to inside of the bar if you decide to go without the other type of bar ends, like the Rhino's. I recently installed some Acerbis Dual Road hand guards that only attach to the bar end, and left the Rhino's in with the intention of changing back to the bar end mirrors later this summer. Just had to get a slightly longer bolt.
