Bike almost feels like its floating side to side. What to look at?

First off, hi, I'm lugoismad.

Here is my 1975 Honda CB750F



Last October I had the rear tire blow out on the highway. Not a fun experience, but I managed to keep her up and roll to a stop. I had the tire replaced and the rim balanced and tightened.

I'm not sure if its just my mind playing tricks on me because I'm scared of having another blowout, but occasionally the rear end feels like its kind of floating around left or right. I've checked and everything is tight back there. Is there anything I may be overlooking?

Thanks!
