To set preload you don't have to remove the shock, you can can set the bike on a box with swingarm unencumbered and wind off the preload ring until the spring spins by hand. That is zero preload. Then wind in ten mm of preload and see how it acts, adding more as it's needed. I know that my Ohlins shock has 1mm of preload for each rotation of the preload ring, which makes it quite easy to set the sag. Les from LTR has a sticky (

According to the sticky you want 105-108mm of sag, and I found this to be true as 95mm of race sag for me caused the bike to be too twitchy, and the extra 10mm of sag helped out a bunch.
