He designed his engine split horizontally so it didn’t.

It makes sense even if it’s not accurate. My CD175, CB250, CB450 and CB750 were all totally oil tight. Every BSA and Velocette I owned were incontinent!

Great collection of Honda's to have owned and enjoyed, I have also ridden the CB175 a great bike that punches well above its weight, the CB350 twin, the early four cylinders from 450 cc upwards and of course the massive CBX six cylinder monster of a machine. When I think about buying a 70's bike for my collection, although the Kawasaki triples and Z900 along with the Suzuki Kettle feature strongly in the line-up I'm always drawn back to a Honda 750 4, the trend setter, the mould breaker, of the late 60's and early 70's.
