Front brake issue

So I just got a 2012 daytona 675r and am having a pulsation issue while braking in the front end.
I have checked run out on both disks and they are about 0.006" under the 0.0113 max spec.
Thinkness I am at 0.157 over the 0.138 min.
It isn't a very strong pulse but enough to be noticeable.
I have sanded the disks and pads a couple times and didn't seem to change anything.
Any ideas what else it could be?
Headstock seems good but I am going to check properly later..
Any help would be awesome.

Somewhere, maybe on this forum, I've seen suggestions that the buttons can become frozen. Other than that, all I can suggest is a change of pads. They do age out.

New rotors. Tolerances are too tight to fix them, and you may just end up making it worse. You *could* try to do the floating rotor mod, might help out a little bit.

Has the bike been tracked or raced? Stock rotors are shyte, they don't hold up to the heat from track use. I replaced mine a couple of times before I finally grew a brain and bought Brembo T-Drives. All that said, for street use they should hold up ok.

Stock rotors on these bikes are not exactly top notch.. Not sure what your actual thickness on the rotor is, but if even close to being close to the end of the service life, they most likely need replacing.
As mentioned below, some aftermarket rotors will greatly aid in taking out any warped or worn rotor issue. Which pads are you running, and how solid is your lever pressure?

Most of you people are not capable of being your GD self, to damn worried about being politically correct.
