Hi all...I'm new to the forum and I just purchased a Volcano EPX Pro a few days ago. I have a newbie question. One of my shocks was leaking and I decided to replace the oil. I followed the normal procedure (fill to just below the top, remove all bubbles by sliding shaft up and down, and reassemble). Afterward, the shock would barely compress. How much oil should be in these things? Have I missed something simple?
