Spark plug diagnostics
This article was published in the April 1975 issue of Custom Chopper magazine and is in my opinion one of the best ever about spark plugs.
At the end of the page there is a conversion table from the same issue of Custom Chopper that I have used many times over the years when I have experimented with different plugs on my motorcycles
