Wholy f*ck.
You're a genius! :)

Did you machine the entire new seal head? As it looks different from the stock one.
And can you access/remove the HSCV shimstack at the very bottom of the cart? It is somewhat pressed in, and I can't imagine how you could get it all the way out without some difficulty.

Yes, it's not complex. You just have to put the spring inside the head instead of before it.

No, you just can see the top of comp. valve. You'll need to make a similar trick at the other tip, but using an external thread instead of an internal (you have a lot of space to handle it between the cartrige and the stanchion inner face).

I really don't know the usability of this, but it saved the cartrige without waiting a month for the new one from warranty (i'm in Chile). It broke the shaft itself.

What do you mean? The negative spring goes below the seal head (and above the piston at the end of the shaft obviously) but that is the same as stock right?

Yeah that would be incredibly cool. You would also have to machine a new bottom end too though right? to house the shimstack unit, and also the threaded end for the footnut.

I just think you've done a really neat job, and this is how marzocchi should make the carts in the first place. If the bottom end was also made threaded, it would allow people to change the shimstack and valving completely to suit their tastes. :)

Where did you break the shaft btw? At the topcap threads?

They won't even tell you how to take their forks apart, or how to change the oil.

For some stupid reason they are fundamentally opposed to giving the consumer ANY information. Contrast this with current RS products. It is getting so that my next fork purchaces might not be Marz :rant: :clue:

Awesome mod!!!

Yes, it goes below. I put it IN the cap, and yes, is the same spring.

I don't think to do it right now, but may do it soon. Marzocchi's stock valving fits good enough for me.

Thanks. May be they just protect themself from non expert hands that, when don't work well, talks bad about the brand.

No, at the valve threads.

(sorry about my grammar)

I am sure that is the reason they use. On the other hand, they heavily market some of the products (roco) as 'user servicable', using this as a sales pitch. In reality they don't offer the info to work on it. As i said before, it pushes me AWAY from their products. Would you buy a car that you could not change the oil, or tires, or windshield wipers without sending it back to the mfg?? Why not just warn that the info is for 'mechanics' only and that Marz is not responsible for 'your' work. This type of disclaimer works for many many other businesses as well as other bike parts mfg.


Even as a dealer, there is NO tech info available. That is B.S.!! This was NOT always the case. Up until ~ 2003 Marz made a tech CD available to shops, not any more. Shops are forced to 'experiment' on customer equipment!

I think that this mentality (no info) will lead to a large percent of customers doing NO maintanance at all. Will the fork perform well in this case? In addition, technically minded customers (the inteligent ones who Marz should WANT riding their products) will look elsewhere. They would be MUCH better off with simple maintainance instructions. Fox has 'hands off' parts to their forks, yet they offer info about other levels of service that can be done by a mechanic. RS has every possible bit of info available to ANYBODY out on the web.

Marz has the idea that information is dangerous..VERY naive!!

Agree in almost every point.... but is true that information in wrong hands is really dangerous.
