Hey guys, just picked up used Kei Office Suspension(4 way adjustable) not the XRs. Just wanted to know, How can you tell if a shock is blown or not? I lowered the spring all the way down so I can press down on the shock. when I press down on it, it takes time for it to be pressed all the way down(Set at #4 on shock) when I pull up on it, its just and same and pressing down(needs a bit of force) they dont go back up on their own but they seem to feel "kinda" stiff when pressing down. Kinda hard to explain but can anyone answer this?

one more thing, when I change the shock settins to 1, feels a bit easier to press them down, but they still dont go up on their own
