Have we concluded yet? Is the NGK D8EA sparkplug the former D8ES or the former D8ES-L plug?

D8EA is same as D8ES. The D8ES-L was sold as a "half" grade

I had to check CB750 shop manual.
I guess the plugs changed in 1977, year more than bike related.

From K6 spec

(From the F2 spec) F3 and K7-K8 same plugs.
