Anybody ever rebuilt and recharged an external reservoir nitrogen shock ? I just pulled a seriously abused Fox twin clicker off the bike and replaced it with a Works that I got a deal on. There's an ebay site [URL]http://stores.shop.ebay.com/Vintage-Fox-Shocks__W0QQ_armrsZ1[/URL] selling rebuild kits and manuals for fairly reasonable prices, but I'm not how you manage the recharge part.
