Not everyone understands what a completely rational process this is, this maintenance of a motorcycle. They think it's some kind of "knack" or some kind of "affinity for machines" in operation. They are right, but the knack is almost purely a process of reason, and most of the troubles are caused by what old time radio men called a "short between the earphones," failures to use the head properly. A motorcycle functions entirely in accordance with the laws of reason, and a study of the art of motorcycle maintenance is really a miniature study of the art of rationality itself.

You’ve got to live right, too. It’s the way you live that predisposes you to avoid the traps and see the right facts. You want to know how to paint a perfect painting? It’s easy. Make yourself perfect and then just paint naturally. That’s the way all the experts do it. The making of a painting or the fixing of a motorcycle isn’t separate from the rest of your existence. If you’re a sloppy thinker the six days of the week you aren’t working on your machine, what trap avoidance, what gimmicks, can make you all of a sudden sharp on the seventh? It all goes together ... The real cycle you're working in is a cycle called yourself. The machine that appears to be "out there" and the person that appears to be "in here" are not two separate things. They grow toward Qaulity or fall away from Qaulity together.

There is no perfectly shaped part of the motorcycle and never will be, but when you come as close as these instruments take you, remarkable things happen, and you go flying across the countryside under a power that would be called magic if it were not so completely rational in every way.
