I just spoke to Jennifer at RH. Very nice lady. I asked her about the fitment issues with the 2007 SERK and she did confirm that you do need to swith out the billet brake arm for the header to fit and not come in contact with this brake arm. She stated they are still investigating a potential fix, i.e. a spacer or a different head pipe, but no confirmed fix as of yet other than switching out the pedal arm.
She did say that you (dealer) should not bend or alter the pipes as it may void the warranty.
I would be very interested to see what other types of brake arms are available, that would fit, and see what they do to the appearance of the bike. I think one owner mentioned he "shaved" some of the billet arm off to make more space for the pipes to fit.
May cause yet another change in my choice of pipes [smiley=huepfenlol2.gif]. Good thing it is not going to be here until February. I'll change my mind twenty times by then.
