Are you 100% sure the swing arm is moving George. I have taken mine apart before even though it felt free to move but it wasn't until I actually removed the whole thing that I found it was sticking. If the two o-rings are missing from the pivot pin water gets down there (even when you wash the bike) and it results in the pin rusting plus a bit of aluminium to steel corrosion going on results in the pivot becoming sticky.
I would take it apart for piece of mind, clean the pin with a bit of fine emery or wire wool and do the same with the arm where the pivot fits. When you reassemble make 100% the two o-rings are in good condition and sit in the recess. Be warned, Honda OEM o-rings are expensive, do yourself a favour and buy a box of various sized o-rings from eBay, much cheaper and you will always use them.

Hi Dave, I have both O-rings and I can spin the thing around like those olf football rattles! I've really pulled everything out and cleaned meticulously plus new grease.  ;)
