Looks neat mate, get rid of the "broomstick" bars though, I'm sure you have no intention of keeping that aesthetic eye sore there any longer than you have to!
To correct you though, Carpy was there, "back in the day". He's from England, (the birthplace of the Cafe Racer) and he's the right age to have been a young "Ton Up Boy". (as ghey as that sounds............)
As far as going back to the 1970's to collect CB750s, unless you were gonna steal 'em, you're better off buying them now, because "back in the day", most of us couldn't afford one, ha ha! Cheers, Terry.
