It seems to me that all the screws and bolts on my Japanese motorcycle

AFAICT, neither the threads nor the socket required for the sparkplugs
used in my Honda are metric. Is that so, and how did it happen?


Huh? I though ALL sparkplugs were metric - a residual from the days
(~1900)

Well maybe the threads *are* all metric. I wanted to get a nut that
would go on a sparkplug, to make a spark tester, and none of the
English nuts fit. OTOH, I tried all the metric nuts and none of them
fit either.

Get a spark plug heli-coil thread repair kit then drill, tap and thread
insert whatever you want to.
