They are pretty much unridden, thinking about it more I've probably damaged something on the downhill track as I was never aware of the fork feeling strange until I had a spin round GT on wednesday and the first thing that happened was when dropping off a log the fork made a horrendous topping out noise when I lifted the front end and the rebound adjuster pinged off the bottom.
I was planning on gettng the mechanic at the LBS to fettle with them anyway.
