John
Thank you for explaing what is going on in there. Knowing what's going
on, is better than not knowing and wondering if you are screwing things
up.
I did start with ATF and progressed through various oils to 60W. Nothing
changed. Lighter oils perhaps? Mineral spirits? Kerosene? Just kidding.
I might try the lightest fork oil possible.
Thanks for the help.
Kevin, feeling better...

Keven: There are two bushings in each fork leg assembly. One is attached to the end of the fork tube and travels inside the fork slider as the tube moves. The other fits into the top of the fork slider and is retained by a wire spring clip under the chrome seal holder. The bushing guides the tube as it moves up and down. It also retains the fork tube. When you hit a bump and your forks extend fully these two bushings hit - thus the bang. Years ago I installed an oring over my fork tubes b4 assembly to stop this banging. They lasted a short time then disappeared. Perhaps an 1/8 inch thick nylon washer would hold up to the abuse - not sure. It would have to be short because anything you add will subtract from your fork travel. I don't know how preloading the springs with PVC spacers helps as I would think the forks would rebound faster - more bang. Common sense would also tell you that thicker oil would be better, but that doesn't seem to be the case.

I have asked some people about it and all I got were vague answers. The problem is as follows: When I go over railroad tracks, hit a small pothole or something that causes the forks to operate in a severe fashion, the forks compress as they should, and then return to their extended position and hit their stops very hard. It's as if they don't have any oil in them, but they do. I've put ATF in, then 20W50, then 30W fork oil and lastly 60W racing oil. Nothing. Still does it. What the heck is going on? The seals don't seem to be leaking. The bike only has 20,000 miles on it. 3000 put on by me in the past year. If it is something simple I'd like to know. I don't feel like dropping a wad of cash on something simple. Sorry about spelling aluminum wrong. I flunked a lot of english and math in school.
