Brakes, front inner tube, oil change, spark plugs, grease bearings, adjust clutch lever play, brake fluid check, .......a full service is a lot of work. 5.5 hours is fair.
I have no faith in human perfectability. I think that human exertion will have no appreciable effect upon humanity. Man is now only more active - not more happy - nor more wise, than he was 6000 years ago.
Edgar Allan Poe
