Took one to Maxton in Cheshire when I had the forks revalved on an 06 R1, was told they don't generally need rebuilding, just topping up with oil - no charge as I was having the forks done!:thumbup
If maxton is too far for you then you could give k-tec a ring. They are based in coalville. I've had my forks done there previously and they are brill, their number is 01530810625.
road ride i can turn the adjuster fully one way then fully other way makes no diff had a sprint damper on my gsxr and on full i couldnt turn , i know people will say i dont need it but if its on it should work well thats my way of thinking
