I have an MX comp air that I bought used ('04, 85mm), and it's really stiff, even after letting all the air out of both sides. Since people talk about problems with over-filled Marzocchis, I decided to take off the caps and have a look. What I found were black plastic tubes about 3 inches long on both sides. What are those for? Should they be there? They don't show up in the service manual, but they look like preload spacers from the "coil" version or something. After removing them now I get a lot more travel. Have I removed something vital here? Thanks for your help.
