My 93 KX250 is acting weird. I put it on the stand, the rear shock is completely uncompressed, but it seems like there is vertical play in it.. in other words there's some play until the shock begins to compress. When I am going off of jumps it seems to to 'slap' around. Is this a tell tale sign that my bearigns in the swingarm need replacement or is something else going on?
