|   Air hissing sound from a '02 MARS elite fork (rebound adjust | NeD
Jan 11, 2004 1:30 PM | | 02 mars elite......
I have a funny hissing sound coming from the rebound adjuster when the fork is compressed and it also sounds like air is returning into the fork when it rebounds. Any idea what the problem is? The air chamber is on the opposite side. No oil is leaking either...... any thoughts.....HELP?......... |

However, if the sound goes away on the minimum setting, but increases as the rebound damping is increased (with damping increased, the fork returns to extended position more slowly) then it is just the sound of the oil being channelled through the ports to accomplish the damping.
I know when I lost the rebound knob off my SX-R, an actual air hissing sound (as opposed to an oil hissing sound) could be heard on compression and rebound. Manitou said that was normal. When I installed a replacement knob, the air sound went away. Since I use very little rebound damping, I don't hear any noise on compression. If I increase the damping, I will definitely start to hear the oil being "restricted."
Hope this helps.

Air was infact getting sucked into the lowers as the fork extended after being compressed. Luckily, the solution for me was simple. All I needed to do was cycle the small piston at the center of the post with the end of a small screwdriver. This cleared the obstruction (the smallest stick you could imagine) and the fork worked perfectly afterwards.

| Yes. That's another possibility I forgot about. (NM). | chris2fur
