Let see... Only things on my Norton that are Commando are the pistons, 2S cam, and timing cover. Yesterday I took my Commando timing cover for 130 mile ride. About 12 miles of it was in the mostly blind corner twisties behind a GT3 spec Porsche. I haven't had that much fun since I was in my 40's. I did not try to pass the Porsche, because that thing could accelerate a buttload faster than my Norton and the driver had enough chops to keep up in the corners. Woman driver. I probably would have killed myself trying all things considered.
Later in the ride I had to make a decreasing radius downhill right hander exit from one country road HWY to another. Only a 55 mph turn entrance. However, that turn reminded me of how crappy 7" drum brakes are. Ran out of slow down right about the apex and ended up crossing the double yellow by about 10 inches. Fortunately, nobody was approaching.
No breakdown story, but my catch can was over full of froth by the time I got home. It was hissing like a snake. Looking into that, moving some wires around, and after 10,000 miles with the spin-on filter on the feed side of the oil pump, gonna see if it makes a farts worth of a difference swapping the lines so the filter is on the return side of the plumbing. I've always had good oil pressure with it on the feed side regardless of what has been said by anyone anywhere. I'm actually doing it to see if it reduces the frothy goop. I'm doing it even if that doesn't make any sense at all. That is how I roll.
