I just had the same thing happen to me about a week ago on an SL tulio. I jumped off a wall and lost all hydraulic damping instantly. I have yet to disassmble it but when I do I can relay what I find. I have 3 of these SL forks in different colors and trim (tulio, disc only, disc &v brake). I just put Enduro fork seals and an oil change in one and have another set of seals and a rebound assembly on order for one apart on my bench. Once that one is back together I'll pull apart the last one. I can say that if it just came back from service and you imediatly noticed the problem it could be some thing as simple as air in the dampening catridge. In my case something happened on the inside to make this happen. I'm kinda curious to find out what the deal is but don't want to have parts for two forks scattered on the bench. Rock Shox does have some nice service manuals you can download off there web site for these forks.
borg said:I rode last weekend and took a down hill creek section that has some slower rocky stair tep sections. It seems like my forks are really over soft as I roll down over these stair step sections. I weigh around 191# in street clothes so with camel back etc. say 196# (+/-). It feels like there is no rise in the spring rate and compression damping adjustments didn't do a thing. I have the heavier (blue) spring, had it in even but switched back to the one (red?) that it came with. I recently had them serviced and re-bushed at R.S. I'm at a bit of a loss. Any suggestions would be greatly appreciated. Heavier oil ?????????
