Hi,
A lot of motorcycles have an unofficial name, some are logical, some not. Honda CB72 is named hawk in the US, his bigger brother (CB77) is named superhawk. The CB750 K0 is called sandcast.
Is a CB72 also a sohc, but with four valves instead of four pistons ? In fact the CB72 has two different cams, so its a dohc4 ?
The CB400 cylinder head is also partly sandcast, can it be named sandcast too ?
In fact all above engines cases are moulded in the same way (except the CB400 cases), why is the CB750 k0 called sand cast then ?
something to think about,
Jensen
