I just put on a new Progressive 412 shock on my 1992 K75S and don't need the original shock. I am pretty sure this can be rebuilt if someone wants to. It isn't leaking. It was just a little too soft for my taste. I didn't even think about adjusting it until I already had the new one on. I posted it on eBay starting at $40 +$15 shipping. I have no idea what it is worth.
