Lighter springs for the X ?

[KDXfile]

I'm having trouble getting the proper 4 inches race sag on my X. It's got about 20+ hours so it should be broke in enough to loosen up.

I weigh 165 with gear and the most I can get by loosening the preload is still less than 3" and this ends up with around 1.5"+ of static sag.

Common sense says my rear spring is too stiff but all the charts are saying I've got the right spring (stock rear is a 4.8).

Anybody else having the same experience and went with lighter springs?
