Topic: Help with rear sprocket / bolt patterns / teeth

[riffman12]

Apologies if this is a bit confusing. I'll try to be concise:

So my bike is a '76 750F with a '77 750F front end, rear swingarm, and wheels (for dual disks). Wheels I got with the bike were bent so I bought a pair of comstars from a '79 CBX. Everything lines up correctly, only issue is the rear sprocket:

The bent wheels that came with the bike use the older bolt pattern for the rear sprocket

The new CBX use the 5 bolt rear sprocket, but it's only a 35 tooth rear sprocket (much smaller than stock).

Where can I get a rear sprocket with the CBX 5 bolt pattern that has the same correct amount of teeth for a '76 F? (48T i think?)

Did they continue the CBX bolt pattern for future sport bikes?

Thanks for the help

you might only be able to get a 38 tooth rear for the cbx. You would want to drop the front to a 13 tooth, then you should achieve close to stock ratio.  I guess that's ok.
