Anybody know how much oil to add to the damper side on a 2003 RS Duke XC fork? I have seen a spec sheet call for 125 - 145 cc/ml and another calling for 95. I added 140 the first time around and was getting a horrible clunking. Rebuilding now and was wondering if the clunking was because of too much oil. Worth a try to change it up with the smaller amount of oil, but just thought I would ask since I can't find a spec sheet specific to a 2003 fork anywhere.
Thanks.

the Barnett's manual said use 140 cc/ ml for your forks. if there is clucking then something is not in right in your rebuild . it would not because there to much oil in the fork .

Can't figure out the clunking so thought I would break it down again and at that point noticed the discrepancy in the oil volumes. Thanks for the info and for the link. Still have the clunking and can't figure it out to save my life. It is like it is 'topping out' against something. As the fork starts it's rebound (regardless of how far depressed) I get a clunk, then the dampening kicks in and the fork rebounds. Wish I could explain it better.
Any ideas? I can't figure it out or imagine what would be happening inside the fork...
