I just put an ohlins shock on my 97 gsxr 600, it is a racebike. I am really unfamilar with suspension. I will be using the shock on the track, I set the sag. my measuring but i tried to make adjustments to teh sag, by turning the preload adjuster knob like the ohlins manual states, am i doing anything wrong? i am setting it up for a 1.875 sag.
