Removed the forks today and am in the process of installing a fork upgrade kit. My fork gaitors were quite dirty inside, probably from a slow leak somewhere. A few questions:
I noticed the fork stanchions have some pitting and corrosion on them. When I slid on the new fork oil seal, for example, I could hear it scraping against the corroded areas of the stanchion. Can I just sand these areas down (there isn't a lot of it), and assume the fork oil will keep them from corroding more? Or do I need to replace them completely?
My upgrade kit came with some paper washers. And while I haven't completely dismantled - yet - the lower fork damper tube components, I have not encountered any paper washer in the upper areas. In looking at the diagram, it appears there's supposed to be a paper washer on top of the fork top bush NMT. Is that correct? Again, my old set-up did not have a paper washer in that location.
The fork collars. Mine where abused repeatedly by the previous owners; obviously they used either big pliers or a pipe wrench to take them on and off. I'm not necessarily concerned about their appearance (rough) since they get covered up with the gaitors. But should they be pristine in order to prevent any future leakage? I know that probably has everything to do with the condition of the threads, which seem to be in okay condition.
I've got some Progressive springs ordered and will be installing them in place of the old ones. I was wondering, finally, what is recommended as the optimal fork oil?
Many thanks, in advance, for any help.
Cheers--
