Default Riser bush sleeve - how much clearance?

I'm about to change my existing riser bushes for poly ones, but I'm just wondering how much clearance there should be between the steel bush and the riser bolt? I've measured the bore of the old steel bush and it's 0.515", and to me the bolt (diameter 0.495") seems rather sloppy in the sleeve. One of the things that's annoyed me is the 'click-click' of the bars when I hit a lump or hole in the road and I'm wondering if this is due to the sloppy fit twixt bolt and sleeve. I was going to knock up a pair at work and reduce the clearance, but thought I'd better check if there is a reason for the clearance being this big, half a millimeter in new money.

Any thoughts?
