I've been playing around with my 2001 SID SL. For some reason today when I went to put more air pressure into it, it was finnikey to get air in, and when I took the sock pump off some oil had leaked out. It was only a thin coating on the top chamber, but on the bottom one a noticible amount of snot-like oil came out, enough to cover one side of my finger for about an inch.
So...whats up with this? Thanks for any replies.
