Almost There!

I have a brand new 2005 Mongoose Thunderball with Marzocchi Dirt Jam Pro forks. When I lift the front wheel off the ground for a wheelie or jump its sounds like the suspension bottoms out causing a very bad noise. I have 35psi in my shocks as the recommended is between 30-40 for my weight. Any sugestions?

put a zip tie around the stanchion (upper fork leg) and push it to the bottom (where the boot is) and go do a wheelie and when you hear that noise, measure the distance of the zip tie from where it is and where it used to be and check to see if it went more than the advertized travel. put more air in as needed.

also, is the 2005 Mongoose Thunderball good for my 1st moutain bike, i own a Hoffman pro BMX and now started to jump in the bush, was this a good bike for that price range?

I have a Marzocchi Dirt Jam Comp on my 2004 Kona Scrap, It was a replacement for the stock fork that broke. There is not much information out there on the Dirt Jam forks, I could not even find the fork listed on the Marzocchi website... Anybody else out there have the Dirt Jam? or seen any information?
