Forks

I need some new forks, I just bought a Ironhorse Porter 24" and the forks on it are pretty much wasted they are like pogo sticks and I tried to change the oil, etc. like the manual I found said but they still work the same.

Anyway does anyone know what the best rigid fork would be and what all would work for this bike, I need something by this weekend if possible.

Thanks

Yeah I noticed that Supercross fork, I am only worried about the fork not being tall enough.

I am only going to be dirt jumping and riding at skateparks, rays, etc.

Id rather have suspension still just dont have the dough right now.

But what kind of difference will this make if I put a fork on it that is 2-3 inches shorter than the one on there now, will it just lower the front end, or affect more than that?

I found a Identiti rebate fork, and a DMR trailblade fork, they both say will work for 24" they are both a little shorter than mine, but not very much, like mine is 20" these end up being like 18" or so, I assume this would still work fine, they must cause it appears lots of people run them on 24" and 26".

But I also found a different manual for mine that show way more psi and a way too adjust the internal rebound which the other one didnt say anything about that so maybe there is still hope in the forks I have.

They are 2006 Marzocchi dirt jam pro's and I found the problem now that I have the correct manual took them back apart tonight and the cartridge rod( or I assume its called that from my MX experience) is supposed to have threads at the bottom where it screws into the nut thing thats on the forks, and thats also how you adjust the rebound.

Well guess what the threads are gone, so the rod is just sitting in the forks with nothing to control anything.

So I am screwed basically I have no clue where to buy that peice or if you even can?

If anyone knows where I can get that let me know, if not I am bikeless till I get a rigid fork.
