I apologize. I even used the google search but can't find the info. Does anyone rebuild/mod the OEM R100GS rear shock and is it worthwhile to have done? I have a WORKS on the bike currently which is getting spongy and before I send it for rebuild... I have an OEM leaker in very nice condition that was given to me but if it's not all it's cracked up to be, or if nobody does it anymore, I'll just stick with my WORKS.
