I've been following this thread thinking .... are you trying to fix something that isn't actually broken. In your pictures in the first post, I have to admit I can't actually see any obvious out of roundness wear in any of the components. It may be there, but I just can't see it.
So .... aware that my 750 has a crap load of slop in the side stand pivot, I just went and measured it. With the bike on the center stand pull out the fitted side stand so its straight out from the bike at 90 degrees. The return spring will be pulling it upward. Push the side stand down to the other side of the 'slop' and measure the amount of travel at the outside end of the side stand. The slop in mine is 42mm, measured at the outside end of the side stand.
If your bike isn't a 750, just forget everything your just read as it may not be applicable. If it is, trust a comparison may be helpful in seeing just how much wear you are really dealing with.
