ANother Thought....
I am in the tool business, we machine the parts and assemble power tools.
My front brakes on my '04 Speedmaster and my '06 Tiger both displayed the pulsing you guys described. I checked the rotors for warping (or runout) and it was negligible. Then I checked them for hardness at work and found variations around the perimeter. They were incorrectly hardened during the heat treat process after machining and had "soft spots". This will cause the pulsing under braking. Triumph had some bad rotors from a supplier named Sun-Star (I think I have that right) and have had to change quite a few out.
SO if your dealer says they aren't warped or are within runout specs, ask about the heat treat issue. AN informed customer is a lot harder to say no to.
