sprockets

Don't know about tha, I still ride mine in the spirit the manufacturer intended, thrash the nuts off it, live at the red line! ;D CB750 F1's had "SUPER SPORT" on the tank, so I ride it accordingly, and use regular 530 non O ring chain, never broken one yet!

Bryanj:
The 630 was standard on the 750F2 and the CBX1000 and used as the life before change was extended as long as you read the book and only used hypoid 90 to lubeb it

hector2800:
I think those sprocket sizes are right for an F2 so maybe you picked up some f2 wheels and engine.

Spitfire:
In the 1970's I got fed up with ruining chains on long runs to rallies and bike race meetings, bombing down the mororways flat out, stopping at the services, buying a can of oil, pouring it onto a rag and soaking the chain to get the kinks out,  so I fitted a Renold 3/4" conversion to my CB750K1, worked great, still have the sprockets somewhere.

Perhaps you have one of the old aftermarket conversion kits like this one:
