I finally got around to working on the Triumph this weekend. First up was adjusting the chain slack. I really should have addressed this sooner. It's so easy on this bike. Next on the list was adjusting the steering head pre-load. You need a fancy wrench to unscrew the top cap... but I found that the wrench that came with my angle grinder fits perfect. I was doing this to cure the slight clunk I was hearing when applying the brakes (mostly noticable at a near stop.) After doing the adjustment I finally discovered the source of the clunk. It was from the floating brake rotors. Floating brake rotors use a center hub, with a seperate rotor that is connected to the center hub using metal buttons. Not being directly connected helps prevent warping, gives a better brake feel... and it's cool. Since the rotor is loosely connected to the center hub it moves a bit as the brakes are initially applied... this is the source of the clunk. Mystery solved, I decided to flush the brake fluid. Again an easy job I should have done sooner. The brake lever was noticably firmer... I doubt the system has been flushed since new. Triumph's have some of the best brakes around... mine were already good, I'm anxious to see how much better they can be.
