I have an '85 900 and the knee guard dampers on the rear of both knee guards have separated. On side is steel and the other side is rubber. I need to repair these to get the bike ridable again. However, I'm a little worried about using the wrong adhesive/epoxy and that they just fall apart again or look terrible. It looks like the left side may have been repaired once before, but that was over 25 years ago because I have owned the bike since '92 and I have never needed to mess with them until now. Does any one have any advise for the best stuff to use?
