Topic: 1970 CB750KO rear sprocket - where?

[Johnie]

Installing a new EK o-ring chain on my 1970 CB750KO project that I started a month ago. My Honda dealer has the new front OEM sprocket, but says the OEM rear sprocket is not available.  Western Hills, Bike Bandit and eBay is also not available.  Any other ideas before I have to side with aftermarket.  My original has 17,000 miles on and looks fine, but I was told to replace both sprockets when I install my new EK o-ring chain.  Or, do you think I should just use the old rear sprocket? The OEM #41205-300-000.
Thanks for the expertise.

I would opt for a new, aftermarket sprocket over the old original one.  But hey, that's just me.

Looks like Yamiya has the OEM for $100.  That may be my only hope if I want the OEM look.
