Hey Tom,
Before you go tearing everything apart, I would try the old 35mm film trick! In the "Old Days" you could get a piece of 35mm camera film and slide it in the lip of the fork seal. Run it around the the fork tube once or twice, and it would reseat the seal lip and clean out any foreign particles trapped under the seal lip. Since 35mm film is pretty much a thing of the past, I use .005" S.S. Shim Stock.
If you can't find any shim stock, PM me your address, and I will send you a piece to try out. This is a much easier fix than replacing the fork seals, or the O'Rings on the anti-dive unit.
Let me know if I can help!
Earl
