Not even had this kind of experience!!! 
HELP!!! 2004 Marathon S 120mm
Badly need your advice guys;
This morning while I was cleaning my bike after a morning ride, I noticed some kind of sound on my 2 months old 2004 Marathon S 120mm when I tried to compressed the shock about halfway of it's travel by holding on the front brake and pushing on the handle bar.
Sounds like something is touching inside the stanchion on the right side (with the rebound adjustment). A clunking sounds like ..."tak".."tak"...everytime you compressed the fork.
Is this normal or something wrong with my fork. I feel also the the fork was not active as before on small bumbs. The only thing that I did remember was turn the rebound knob while I was riding.
Is this the reason for that...Please give me your feedback.
Thanks a lot...

Hold the front brake so the wheel doesnt move then rock the bike forward then back afew times. Does it make the noise then?
Could be the sanchion tubes that go into the top crown is making that noise. I know some of the older forks from Marz did that.

Exactly sounds like that, and it only happens on the right leg...a knocking sounds once the fork was compressed halfway...
try lifting your front about 1 ft high and let go.
Mine sound like something is loose from the inside but my LBS say it the sound of the sanchion tubes that go into the top crown is making that noise. Are all the Marz like that?

My fork was just 2 months old and I still can remember how active it was even on the small bumbs...Now, it rides like a DJ3 with too much air preload on it...only activates on a big bumbs...
I'm having the same problem on my 2 month old marathon s. It feels fine, but the clunking noise is killing me. It makes the noise right at the start of the stroke; once in the stroke, it's silent. It really sounds like a loose headset, but the headset is fine.
If it is the stanchions making the noise, can anything be done about it? Any other suggestions?

OK Don...I had a good news for you...If the clunking is on the right leg (rider perspective) not the left leg(ETA side), then we have the same problem.don_o said:I'm having the same problem on my 2 month old marathon s.

I found out that the mini rebound shaft was unscrewed from the HSCV damper...
possibilities how it happen??? probably by turning the rebound fully open(counter-clockwise) to lesser damping while riding...
How to fixed it??? you need to know first how does the internals look likes in order for you to safely removed the top cap and not to totally screw your fork.
I suggest you read first and understand information here. Thanks to DAEVH for his wonderful information there;

The information actually contains how to change oil for Z1FR and Z150 which shows pictures of the internals...which I supposed the same or identical with the Marathon...
My fork is now back to normal...
Anyway, good luck to you.
