Thanks for the helpful information! I kept digging around and finally found this thread on mtbr.com. This guy has a 98 SID fork, so slightly different than mine but with some similarities. Turns out we both need a needle adapter for our shock pump. These are the type of adapters that are used to pump up footballs! Interestingly enough, my DH, being the sports fanatic that he is, says he has one. We'll see if it will work with my shock and pump. Apparently in later models, Rockshox went to regular schrader valves on their forks. There's also an option of purchasing one of these to replace the top cover on my fork, but if the needle valve works, I won't bother. I'm sure a new fork is in my future as I'd love to have lockout capability for certain types of riding, but I don't want to spend the money now, and I do love the blue color of my fork!
