I have a manitou minute :2 air sprung 100mm fork and when I iar up the spv valve there is no dampening in the fork at all.When I let every bit of the air out of the spv valve ( they say you are suposed to run no less than 30 psi in the spv valve) then I have dampening but It wont adjust with the adjuster,it is just full on slow.Anyone have any ideas?Thanks.
