I just went thru the process of pulling the pin on my '15. The guys are right, it's an easy process but the most complicated part should not have been complicated at all but it's been made complicated by a marginal (at best) design, and that's the removal of the chrome "horseshoe" under the ignition switch. What a pain. I didn't break mine like some have done (thankfully!) but I sure was afraid I would.
I decided to use a marks-a-lot black ink pen to put a witness mark on the side of the handlebar clamp and then on top of my handlebar so I could see where it was positioned at stock. (This witness mark also helped me to re-center the handlebars before tightening them down). Then I put them where I wanted them and partially tightened the clamp. Turns out I'd rolled the handlebars upward/forward about 3/32 of an inch at most per the witness mark, but the grips moved up substantially, perhaps 2 inches or so. So far I like them in the new higher position, but I will need to put some miles on it before deciding whether or not to move them again, and which direction.
