    Pike lower service. Air in negative chamber?

    I have the lowers off, I let all the air out and even removed the valve core.

    There is still some pressure pushing the air-side piston rod to full extension. It's not exactly a firm pressure, I mean I can push it all the way with hand force, but should it be there? I assume there is pressure in the negative spring, but shouldn't it suck up the rod, not push it down.

    Is this something that may be reducing my small bump compliance?

    Sorry if this is a dumb question.

    It might be the negative air chamber, a vacuum was likely created after you evacuated the positive chamber and cycled the piston rod.
