I had the Gold valves installed this last March. I sent my forks to California, told them I,m 250#, and I like to tour as much as throwing the bike thru tight corners, at high speeds and they set it up with their expert knowledge base. I also had them select new springs for me. They bike handles phenomenally now! Then I went to the Works folks and had them build me a proRacer mono shock with adjustable rebound and compression damping. The bike now can't handle any better, in my opinion! It's perfect for every kind of riding I do! Note that they have to deactivate the anti-dive mechanism on the left fork, for ST1100's to install the " cartridge emulator " with the Gold valves. Not to worry, cause if you have the springs they select for you, you don't need it.
