You gotta love wrenching on your bike if you buy that one. No offense, but that vintage Norton was known for oil leaks, and mechanical 'needs'. When the CB750 came out, in '69, it was a game changer because it didn't require wrenching every ride, no oil leaks, no tweaking required, on a routine basis. One reviewer stated that the Honda was a boring bike, compared to everything else on the market, at that time, because it just worked. Cheers!
