I just joined the forum so I can ask this question. I'm a great believer in forums but I've owned the 2001 ST1100 for three years now and never had an issue before. I just put new seals and oil in the forks. Had a little trouble getting the bottom bolt out of the right side on disassembly, but I soaked it overnight and hit it with an air gun the next morning and it came right out. I don't know if that would have caused the problem, but when I put it back together, the bottom bolt won't tighten up. At a certain point it just spins inside the bottom of the damper rod. My manual doesn't show the piece that the bottom bolt screws into, only the oil lock piece that slides over the end of the damper. What is supposed to keep the threaded piece from turning, and if it has to be replaced, how does it come out? I haven't taken the cartridge apart yet.
