I bought a Marzocchi 66 with 150 mm of travel thinking that the "travel change kit" would be similar to spacers I had on my DJ fork. After checking out a few bike shops, I was told that it was a matter of removing a spring from the bottom of the fork and moving it to the top. Does anybody know how to change the travel from 150 mm to 170 mm on a 2005 Marzocchi 66 VF? Tips and recommendations are welcome. Thanks.
