    New question here. question about/troubleshooting front shock

    hi. when i compress my front shock, i hear what sounds like air escaping. the last couple of nights, i filled it up and then hung it up (by the front wheel). 24 hours (and no riding) later there was no air. any ideas what could cause this? the shock is a 2001 manitou mars elite. any help is greatly appreciated

    There's the problem.

    Try not hanging it upside down and see what happens.

    Two reasons you may be losing air are 1)The seal on your schraeder valve may be suspect. If this is the case you should be able to purchase a new valve core from any auto supply store and replace. You'll also need a valve core removal tool, also at auto supply store and they're pretty cheap. 2)However, first check the positive air chamber to see whether it is dry. Remove all the air from the chamber and remove the top cap from the air sleeve side. You will see a positive air chamber with a piston. There should be a small amount of oil in the chamber. If the chamber is dry you will have an air leak. Fill a couple of cc with either 5wt oil or probably motor oil will do. Do not fill the chamber completely but add a small amount.

    Hopefully these fixes will solve your problem.

    The seal on the bottom of the leg is an oil seal, not an air seal. It also has a piston moving through it and is subject to wear.

    When you hang your bike upside down, the air rises to the bottom of the fork. And possibly leaks through the seal. It may or may not be leaking oil; as air is smaller and can get out through a more minute imperfection. Even it is leaking oil, the oil will be trapped inside the lower leg, so you might not notice.

    But check the Schrader valve, too.
