Hi all, I'm looking to rebuild my son's 2002 Rockshox SID SL Dual air fork, as it used to leak oil, and now doesn't, and he at 50 pounds can't budge it, and me at 200 pounds barely makes it move. It is a great lightweight fork that I bought used, but the seller (EBay), should have been a little more honest in its condition. So if anyone can help me know what rebuild kits and what weight shock oil to buy for a little jammer, I (and my son) would be much obliged. Thanks - BS
