The rear shock on my 93 KX 500 seems to have no compression or rebound dampening. This would seem to indicate to me that the oil is all gone from it. Does anyone know how or know a site I can check out to tell me how to do it??? The Clymer mainenance manual I have says to take it to the dealer or other suspension shop for servicing. I just want to be able to get thru the rest of the year on it and get it professionally serviced over the winter.
