    sooo? how much pressure are you running in the main and evol chambers on your skids front and rear shock?

    I weight around 200+ ready to ride and have my front evol 3s set at 55psi for the main chamber and 90psi for the evol chamber

    what I am trying to figure out is the skid shocks. I don't really understand how the two shocks work together.

    the setting you mention work perfect for ski shocks for trailer riding, you have Evols in both center and rear?

    Rear shock will need more main chamber air, usually 100 -125 and the evol chamber would need more like 200. Center shock, I would keep on the lighter side more like the skis, like 65 and 100. Then you have yo go by feel, if its hitting hard in the bars, then its skis, if it hits hard in the butt, then its rear and if it hits hard in the feet, its center.
