If it's actually losing air only when you ride it, that makes me think maybe the air piston o-rings are dry, so it could be quick and easy to test by adding some oil to the air chamber. Check the service manual for the oil volume and type, I think RS calls it Red Rum, which I think I've heard is the same as Torco assembly lube?jbsmith said:I have a SID and I was checking the air chambers the other day - when i pressurize them and let the fork sit on its own they hold air fine. However if I cycle the fork the positive chamber looses pressure. What does this indicate?
Be aware that stanchion oil seals/wipers are not the same thing as the air spring o-rings and seals. If you are planning to replace the oil seals, while you have the lowers off is a good time to service the air spring with an o-ring kit like was mentioned above.jbsmith said:Thanks for the insight guys. I am geting ready to put enduro seals on it because it has been leaking oil at the stanchions. Sounds like It may not have enough or any at this point (it has been sitting for a while too), so when I redo the seals, i will replace the oil and see if that fixes the issue. If not I will get a seal kit and redo the seals.
