Like the title says - I have a friend with a circa 2004 Demo 9 and a Marzocchi 888 fork that was serviced by a local-to-him shop in Denver, Colorado that is now leaking profusely. If I recall correctly this generation of Marzocchi had separate oil seals and dust wipers, and I suspect that the wipers were replaced but perhaps the oil seals weren't (or were done incorrectly).
So far Dirtlabs in Colorado and Avalanche have both declined to service the fork owing to age. Any other ideas? I would offer to do it myself but my friend is a 6 hr drive away which makes it impractical, and my expertise only goes as far as lower leg service and I figure a full service of all seals is probably a good idea.
