20:1 you're missing the conic bushing between the clamp assembly and base unit. Go to the Park site, find the parts list for your stand, and you'll see the part, you need.
FB, great suggestion.
So, I checked the site and they do have a
two page illustration for instruction as well as a parts list.
I wasn't able to find anything listed as the 'conic bushing' but there is a cone shaped piece (#7), which must be it? I actually do have this piece. In fact, from the illustration I don't think I'm missing anything.
Part # 9 is there but I was unable to pull it out to inspect it, but I couldn't imagine that would make a difference?
When I tighten it (righty-tighty) it eventually gets to a point where it is so tight that I cannot turn it anymore, however the bike can still freely spin. It's as if there should be some kind of heavy rubber grommet between #9 and #11, instead of simply a washer.
There is an ever-so-slight bend in the threaded rod. Do you think this could possibly be the problem?
Any other thoughts or suggestions?
