When you get it up on a workstand (with both wheels off the ground), take a measurement from the rear axle to a point on the fender right above the axle.
Then take the bike off the stand and stand on the pegs (measuring it while seated is less reliable as you move around some during multiple measurements) in full riding gear, your normal amount of tools, fuel, etc. Have someone pull up on the rear end about an inch and let it ease back down, then measure the distance between the axle and that same point. Do the same thing, but get the assistant to push down an inch and let it ease back up, then measure. Get the average of those two measurements. The averaging takes care of most any drag related measurement error in the linkage. That distance should be 100mm. If it is not, then loosen the preload locknut and adjust the adjusting ring until you get it to 100mm.
After you get it to 100mm, pick up the back of the bike and then set it back down. Pull up/ease down / measure then push down/ease up/measure and average to get the sag measurement of the bike under its own weight. This should be in the 20mm - 25mm range if the shock spring is of the correct rate. Less than that = you need a stiffer spring. More than that means you need a softer spring.
By 20mm - 25mm, I mean it should measure 20mm - 25mm less than the measurement you took while the bike was up on the workstand.
I think that is how it all goes.

The enduro was in Laurel. It was the 2003 Tiger Creek Enduro.
Check those measurements to see if there is any error there. I'll send you a PM about service, or you can just e-mail me.
Thanks,
