Zen and the Art of Motorcycle Maintenance

Chapter 1 (Motorcycle references and Storyline)

  • engine flooding: excess of fuel in the engine; you smell gas when the engine floods because the engine can’t burn all the raw gas; remove plugs to quickly dry out engine, or just let it sit
  • choke: a valve in the carburetor of a gasoline engine that is used to reduce the amount of air in the fuel mixture when the engine is started; hot engine doesn’t need choke
  • spark plug: a device for delivering electric current from an ignition system to the combustion chamber of a spark-ignition engine to ignite the compressed fuel/air mixture by an electric spark
  • points: a switch that when opened, ignites the spark plug; can get greasy (pitted) and then can’t connect
  • ignition coil: a transformer that triggers the spark plug
  • tuning: to make high performance; to put into spec
  • adjusting: correcting clearances (points, spark plugs, tappets)

Do we control technology, or does technology control us? Does knowledge of technology give us control?

Chapter 2

  • stopcock: valve on gas tank; gas should come out when opened — otherwise tank is empty
  • carburetor: consists of a bowl that contains a quantity of fuel and a tube that allows air and fuel into the engine through intake valve (when air is blown over the top of the tube)
  • piston: transfers force from expanding gas in the cylinder to the crankshaft
  • seizure: can be caused by overheating; pistons expand from too much heat, become  too big for the walls of the cylinders, and lock the engine and rear wheel
  • tappets (cam follower): adjusted to allow intake and exhaust valves to close fully

Do we rush? If so, why? What is the distinction between efficiency and efficacy?

The Shop

  • Motorcycle tasks assigned (bottom end, clutch, electrical, fasteners, fork, frame, top end, wheels)
  • Parts of bottom end, fork, frame, top end, and wheels disassembled
