Does anyone here know a bit about the 40mm Marzocchi forks on the 2010 models? My 2010 280 Pro TxT has had a broken rebound adjuster since the first week I've owned it. I finally got around to ordering a new rebound-side fork cap, thinking that the adjuster was part of the cap "assembly". That's how it seemed to appear in the parts diagram at www.trialspartsusa.com .

I got the new cap today, but it doesn't have the brass adjuster part of the assembly in it. It does have the little brass air bleeder screw, but no "clicker" at all.

I'm wondering if the broken adjuster/clicker is part of the fork cap, or possibly part of the cartridge rod somehow? Added in EDIT: Is there possibly some sort of an "adjuster assembly" that screws into the end of the damping rod, and then slides up into the fork cap, and seals with o-rings? I'm really grasping at straws here. I have not had these forks apart, and it's been a few years since Iowned my '98 KTM 300, which had conventional forks with one side adjusting the compression, and the other side handling rebound chores,

Would anyone have any idea about this? I've been told this is a fairly common problem for bikes in this model year range.......

Thanks!

Okay. Nevermind. I found out the answer. The actual adjuster itself is indeed part of the damper rod, where it mates up into the fork cap.

Evidentally, Gas Gas doesn't sell only the adjuster alone (which is what's broken on my bike), but it comes as part of the damper rod/cartridge assembly. The price for that little cartridge unit is quite high, so Jimmie won't be worrying about that adjuster any more...... I'll just change the oil & be happy with whatever adjustments I can do with that. Realistically, unless I suddenly develop Adam Raga-like skills, I'll probably never notice any difference anyway......

Thanks,

Jimmie
