I never did like the look of those later beezas, I drooled over the older 'goldies,' they were and still are a beaut looking engine. Pitty about that pissy crankpin with the stupid tapers into the flywheels responsible for the destruction of so many crankcases!
I used to crack test the Goldie crank pin in my old B33 after every second meeting, most times it was cracked . Old stan Ogden fixed it with a parrallel pin.
cheers pancho.
