    2004 Dirt Jumper II

    Take this from someone that doesn't know anything about the internals to this fork...

    I bought a 2004 Dirt Jumper II fork a little while ago. After putting it on my bike, I realized that the guy must have put the hard spring in since it was hard as ****, even after letting out all the air in both chambers. I really don't want to spend another $100 rebuilding this fork with a softer spring, so....
    Has anyone removed the spring and relied on just the air chambers? Is it even possible?

    Thanks everyone

    DJ forks come with stiff springs, since they're made for jumping after all. Unless you weigh like 50lbs, I don't think you can just pull the spring. Not sure it would even work w/o the spring as the air is preload.
    Fwiw a new spring is about $30-40 and you can probably find someone who wants a stiffer spring to swap for their lighter one.

    I know they are usually stiff. But with 6 inches of travel I would expect to use more than 1-2 iches while jumping. I guess thats my main concern, it looks like like my bike jacked up in the front and I am worried about the change of geometry of the bike. I figured with a softer ride that would help that.

    I found a step by step blog that shows how to lower the travel on a 2004 DJ 3 by using some internals of a 2007 model, that seems like something that would be accomplish what I'm trying to do... not sure if its possible though on a DJ 2.

    Update:
    I'm an idiot... I called the manuf. and they said to just go ahead and remove the caps to see if there are both springs are installed. As they were... They suggested to remove 1 side and see how that feels... if its too plush then add a little air to it.
    So I just took out 1 side and it did the trick...
    Good job Marzocchi! I was expecting something more complicated.

    Now I need to start messing with the air settings.

    It is crazy how I came across this thread!

    I was dusting off the old STP that I built up years ago, and I was thinking how stiff the fork felt; it is a Dirt Jumper 2 around the same age as yours, Kubo. If I might ask, how did you remove the spring from the fork? I do not have the manual anymore. What side did you take the spring out of?
    Thanks fo any help
