Okay so I've decided to change the oil in my fork (Marzocchi Z3.5 same as 99 Z3 Long Travel). I emailed Marzocchi for the manual on the fork and they sent it to me. I've got a step by step guide on how to do it but I have a couple questions. First, what kind of oil do I put back in the fork, since I don't know what weight is in there now? I do urban, freeride, light DH type stuff, so I want the fork a little on the stiffer side. Also, is there any fork part(s) that should be replaced when you change the oil? Any other tips or advice that would make the process go smoother please post. This whole thing seems kind of intimidating and I don't want to mess it up.
