Joe Craig had something to say about the inlet manifold design of the 1st iron dommie engine. Apparently it was hopeless, and killed the performance (it was like the early BSA long stroke twins). Amending it to get the performance back, with the little alloy manifold bolted on delayed production for a few months ?, but Bert would never admit there was even a problem....
