There are lots of wives tales that will probably never die. Using an octane too high for the compression is good for the engine, is one of them. If the manufacturer calls for 87 (which the CB does) then using 89 or 93 is a waste of money as it wont properly burn, it won't burn cleaner, and it won't produce more power ... but a zillion " old timers and promoters of the wives tales" will tell you differently.
What MAY make a difference is either burning an 87 non ethanol gas or burning a tier one 87 octane gas which has additives to actually clean up your valve seats, stems and piston tops.
Honda says their engines are designed to run on up to 10% ethanol but no higher. I have never read a study saying ethanol was bad for engines, however I have read where it is bad for rubber and plastic parts. I have also read that it takes more ethanol to produce the same amount of energy than straight gas
If you hang around enough forums you will find many who believe they know more than the engineers that designed the product, and who truly believe the stuff they hear from relatives, friends, neigbors and the local grease monkey with the high school education that has worked on engines "all his life" and will then continue to spread that (mis)information, whether it is based on fact or not.
Try googling some things like " is burning higher octane better for your motor" or "is ethanol bad for your motor", read some findings and make up your own decision, then make your purchases based on that.
Beware of anecdotal evidence, that is not really evidence, but hearsay and happenstance.
