I've read all of the back-posts on lubing the swingarm linkage, but how often do you mess with the wheel bearings? I recall them being sealed. Are these a "run em' till they fail" item? Also, I didn't find anything dealing with the bearings on the actual shock. Any advice here is appreciated. And for replacement bearings, is there an online bearing supply company that might have some cheaper ones for the linkages? I wish the previous owner had maintained these better. You could go broke even putting aftermarket ones in there.
