YXR primary spring specs

[journeyman]

I was informed we aquired a spring testing tool for our machine presses where I work. My buddy in the machine shop (who rides Yammie) and I want to test some of our primary YXR clutch springs on it. Does anybody know the measurements for the preload distance (clutch idle) and the total shift distance (wot) for testing? I looked on the tech pages and didn't see anything ,unless I over looked it. I want to test my Heavy Hitter spring too.

total force is measured at 33mm,not sure what the preload measurement is
