I've got the 11 250xc (stock valving, and sprung for my weight) and have been thinking about revalving for some time now, for more stability in chop and rocks. A buddy talked me into trying SKF seals first. I believe SKF is an American seal company who is now making replacement seals for WP. KTM sells them in their SXS rebuild kit. The only thing I did was replace the seals and bushings as well as fresh oil, inner and outer. Oh, and 15psi in the bladder, not 17. That was Adammoto's recommendation. It made a huge difference in fork performance. It eliminated the stick (stickshon) that you have with stock seals. In fact the fork feels softer all around and easier to bottom because of the lack of friction at the seal. It's a dramatic difference. I was thinking about softer mid-stroke valving but that's not going to be necessary now. In fact, it would be too soft if it were revalved. If I had sent my forks for a re-valve and they came back like this, I'd have been happy with it, except this only cost $100 in parts and oil. Here's Slaven's video if you haven't seen it. http://www.veoh.com/watch/v208749492BP864P3?h1=WP+SKF+Fork+Seals+vs+Stock You know the right ones because they are a greenish blue color with SKF stamped on them.
