I'm following up on this threat after finding it on Google.
I have a 2013 and I've been told by several people that it is not possible to adjust (open, in my case) the handlebar. My goal is to have them more "open"/further away from the tank, which is what I believe you did.
I heard rumors about "a pin" that holds the clip ons in place and makes it impossible to adjust. Your post is one of the very few places where it says the opposite, so I'd love to confirm you can actually open them up a bit more.
