I finally got tired of sending my 55 in to those boneheads at Marzocchi. Tom from R&D finally gave me some tips on how to get more travel from the fork. Once I got it torn down, it was apparent that it neede an overhaul. The instructions are pretty vague but I basically added a stiffer oil to the TST along with some stanchion lube in place of the Marz additive. There are a couple of other things that I did that helped give it a better feel and more range...check it!
