Went to start my bike today and it would not turn over..
Long story short, I tore the bike apart, took apart the starter - it had gotten wet and a couple of the spring loaded pieces from the brush mechanism had gotten stuck / corroded. Sprayed them with a bit of wd 40 and now the starter works fine. I know other people had have this issue and replaced the entire starter assembly. This method might save you a bit of money. I was stuck out in a bad rain storm a couple of weeks ago - I assume that is what pushed water into the starter.
Getting the fans off was no fun! Unfortunately I left one fan unplugged and I have to take off one of the side fairings again :(. Also others have mentioned that you need to remove the headers to get to the starter, you do not need to touch them.
EDIT: I guess I was late to the party - anyone needing a guide can see it here:

The starter brushes were identical to what is posted here: https://www.youtube.com/watch?v=J14K...ature=youtu.be
