I have this near new 630 chain setup on 79. The person who restored before me wanted to keep everything original . I am wondering if I switch to 530, will I feel any diffference in riding or would it be a pure cosmetic change (other than some weight saving I guess)

It's definitely overkill, strength-wise compared to a modern 530 chain, and it's definitely heavier. It's unsprung mass and so has a disproportionately large effect, weight-wise, but OTOH and to answer your question, will you feel a difference? I doubt it. OTOH, if that was worth 1% and you found 9 other things that might give you 1%, you would feel it.

In your shoes I'd leave it there, even if I would not have PUT it there. It's not like our CBXs are fast or anything .

I imagine there's a 2-3lb weight saving once you change sprockets as well. I did a before and after weigh-in when I converted my GS1150 chain/sprockets, just under 3lbs lost. The benefits of shaving weight is cumulative and improvements with each weight reduction aren't very noticeable during casual riding even though they must be present. If it were me I'd leave it as is until it needs replacing and then make the conversion to 530, unsprung weight matters.

With the miles most of us put on, replacement will be required about 2050.

Thanks for the comments. I will leave it as is. I am hardly putting over 1500 miles in an year . Other bikes chew away the ride time from her. Not that it is no fun bike, but newer bikes handle back roads much nicely :) and can stop at a dime.
