Anyone out there REALLY familiar with these engines? Are the notorious for weak oil pumps?

In UK we had CB250/400T and CB250/400N never heard of an oil pump problem ever----Had a few knackered head and cams where numpties did not check/change oil and or filter.


Did have one BRAND NEW 250 where the crancases were machined wrong and oil pressure would not build up unless there was 1 ltr excess oil in engine
