I have it firmly fixed in my mind that my first Honda a 2 year old 1963 Honda 250 Dream square headlight model (I bought the 180 deg cranked SS later) had a chain driven centrifugal oil filter.
Is my memory right and has this technology been dumped by Honda or did they continue to use it for some years. After my two Hondas I bought British for about a decade before I went back to Japanese products .
