"The Japanese bikes were never that much better than the British ones, especially when they were both relatively new, but the attention to detail in the assembly is much more obvious with the Japanese one."
I like to watch the old videos of engine assembly on Youtube, and one thing I've noticed on both a British and a Harley video is the con rods being allowed to knock against the crankcase mouth, something the guy who taught me how to do that stuff (PhD mechanical engineer) would have regarded with utter horror. You do not risk making even the smallest scratch or dent in a stressed part!
Video of assembly of small Honda engine - nothing is ever allowed to bump into anything else. And the workers are wearing white gloves (skin grease can corrode metal).
