If you undo the "chain link" holding the shock shaft onto the swingarm you can rotate the shaft to preload the spring or unscrew the entire shock inards from the frame for servicing (mine had no oil when it arrived). Easily tunable shim stack to suit your weight/riding style too. Way ahead of it's time that way.
I have heard about that but do not want to do this without some extra info.
Do you maybe have some pictures about the action?
thanks!
