Has anyone actually done this before: Rebuild the Magnum fork. I have a spare hydraulic fork and my bike has the "regular" Magnum fork. The spare has no pressure resistance in it which leads me to think that it may be empty. (Don't know. It was given to me.) A glance at the Puch manual suggests that rebuilding either is possible, but where to get those o-rings etc. is the question. Hate to open a bigger problem. Anyone know if those "throwaway parts" the manual says to replace whenever you open fork are available anywhere? What about "generic" equivalents?
