I am needing to rebuild the shock on my CR. I found a few kits for the rebuild but I want to just replace what is needed. I know the bumper is deteriorating and the seal is leaking. Last is I need a adjuster knob. Anyone have one they are not using or know of anywhere I could get one. Here is a picture of the knob I need. but mine is a 88 cr 250...the picture is a 125 shock...but the knob looks the same.
