As for the wet sump in my opinion it is not a problem. If the bike has sat for a week or more between rides I just drain the oil and put it back in the tank. Only takes a few minutes and it just part of the charm of owning one. I have a copy of the September 1969 issue of Cycle magazine and on the cover is a Commando "S" the headline states Norton's Superbike. That term gets thrown about quite a bit by the motorcycle media but for 1970 I would agree. My "S" is fast, smooth, handles great and attracts attention when I park it. In my opinion it has what Peter Egan called the XKE factor. If you park it and as you walk away have to turn around just to look at it then it has it. As for the breed gets better with age discussion I have a friend who has an 850 and we traded bikes. The 850 felt heavy and lumbering to me and he commented on how my 750 felt light and quick to him. It's all a matter of opinion and with all the things you can do to them it is what you make of it.
