No actual knowledge of the issue, but perhaps the washer/shims are supposed to go on the bolt head side of the spring cap? Would they fit in the indentation of the spring cap? Obviously this isn't what the picture shows. Otherwise I was going to suggest what Duck Man already did. Final thought is, aren't you installing this in your Supersport not a Monster? Maybe I'm stating the obvious, but the paper doesn't give specific instructions for a SS.
