I have Worxs shocks on my 1986 R-80 and my 1985 K100. I sent my K100 shock in for resealing and inspection repair of any items that needed to be replaced. It took a bit of time due to parts delays etc... here is the web site..

Note I e-mailed them but Phone Calls seem to work best.

What I did is ride my airhead while the rebuild was being accomplished so it didn't affect my traveling (I commute on my bike)... So do it in the winter if you park it for snow, or have a spare stock shock, or another bike... to use if you need it like I did.
