    Just curious if we have anyone on this board - which I much prefer to KTMtalk - that has experience with suspension tuning on older (2004) KTM two strokes. I've done a ton of reading, ordered a bunch of shims and hope I have a decent formula for re-valving. Any second opinions appreciated. This is my first foray into suspension tuning, and I'm going all in.

    170lbs no gear, racing b-class hare scrambles on black dirt with roots and rocks. Looking to soften the famously harsh, stictionee (new word!) WP forks. But also retain some bottoming resistance since they throw a few big jumps in our mostly technical woods courses. I removed my third bush and spacer, might do the hole drilling mod if needed, I have .42 fork springs and [FONT=&quot]88-250 shock springs[/FONT]

    Thinking I'll build my shim stacks as follows, race on Sunday! :loco This came from reading a lot of old posts and getting a bit of direction from KTMLew:

    This is what I found when I took the forks apart a week ago, two years after a bad experience with a local suspension tuner and racing a very harsh bike during that time:
