Hey Guys- I just built my new X12 2018 and had a question on the center shock that didn't seam right during the build. The kit comes with a single hole piston and 700cst oil. When building the shock and filling the body up with fluid, when I went work out the air bubbles from under the piston it like sucks air from the bottom or something because its so stiff from being a single hole with 700cst. Is this correct or what am I doing wrong.
