What year is it? I know that this is a useless question until I figure out how to add pics with my I-phone. For now I'll ask a question about my antique brain shock. I have a old Epic with the brain shock mounted on the rear triangle. The brain is mounted vertically on the shock. The only adjustment on this one is rebound. A friend noticed that I was getting a lot of movement in the suspension when pedaling on the road one day. I decided to get a pump and adjust the sag hoping that would fix the trouble. I think that this setup is supposed to compress the shock 10mm. I needed to add air to get 10mm sag. I overshot the needed pressure a little so I went to let a little air back out. Should I get oil out of the inflation port on my brain shock? What are good sources for info on maintaining my suspension? I'll post pics when I figure out how.
