I hate to rehash an old thread, but like another poster put up, I have the 550 forks with the center pin in the damper rod. I've already punched out the pin and from the looks of it, the top dome is one piece. In other words, it doesn't appear that the pin is holding two pieces of the rod together. Am I just overlooking something? I figure at this point I should be able to lathe away a small bit of the damper top to fit the emulator and call it good. Anyone else have better knowledge of what that pin is even for? Thanks!
