I. Announcements<\/strong><\/p>\n

    \n
  1. Professor Littman rearranged some of the groups’ responsibilities and focuses. (see the Teams page)<\/li>\n
  2. A spark plug observations guide was added to the FRS 106 Website, along with a Carburetor Tuning Manual<\/li>\n
  3. A new frame was purchased on eBay along with grips and some other accessories.<\/li>\n<\/ol>\n

    II. Recap from Last Wednesday<\/strong><\/p>\n

      \n
    1. Engine Group\n
        \n
      1. Oil was still leaking from the blue motorcycle, so they emptied the oil and replaced a screw and gasket that was overtightened and stripped last year.<\/li>\n
      2. Oil was also refilled at the end of lab.<\/li>\n<\/ol>\n<\/li>\n
      3. Fluids Group\n
          \n
        1. Worked on removing the timing cover on the orange motorcycle.<\/li>\n<\/ol>\n<\/li>\n
        2. Detailing Group\n
            \n
          1. Looked for new handlebar parts.<\/li>\n
          2. Found a method of searching the internet (eBay in specific) using part numbers from the manual.<\/li>\n<\/ol>\n<\/li>\n
          3. Electrical Group\n
              \n
            1. Learned how a bridge rectifier works (converts Alternating Current to Direct Current [AC to DC]).<\/li>\n<\/ol>\n<\/li>\n
            2. Frame Group\n
                \n
              1. Attempted to use the hand press and hydraulic press, and learned many useful tips for the future<\/li>\n<\/ol>\n<\/li>\n
              2. Front Fork Group\n
                  \n
                1. Completed a catalog of most pertinent parts and determined each part’s purpose.<\/li>\n
                2. Ready to clean everything today.<\/li>\n
                3. Learned about the difference between normal springs and progressive springs (on progressive springs, the spring constant changes during the compression process).<\/li>\n<\/ol>\n<\/li>\n
                4. Carburetor Group\n
                    \n
                  1. Discovered a fitting issue with one of the carburetors and will work on the motorcycle it came from today.<\/li>\n<\/ol>\n<\/li>\n<\/ol>\n

                    III. Technical Concepts<\/strong><\/p>\n

                      \n
                    1. Gear Ratios\n
                        \n
                      1. The gear ratios technical data sheet is now posted on the website.<\/li>\n
                      2. In our drive train, the gears change from small to large twice, effectively reducing the amount of revolutions per minute by the time the power gets to the rear wheel.<\/li>\n
                      3. In its simplest form, the power flows through these four components in this order : 1) Engine, 2) Clutch Basket, 3) Gearbox, 4) Rear Wheel<\/li>\n<\/ol>\n<\/li>\n
                      4. Spark Plug Operation\n
                          \n
                        1. The crankshaft’s rotation induces a current in a series of wire coils that powers many of the motorcycle’s components, most importantly, the spark plug.<\/li>\n
                        2. The voltage produced by the engine is relatively small, but is boosted by a transformer to be able to bridge the gap in the plug and create the all important spark.<\/li>\n
                        3. The points mechanism is what controls the frequency of the spark based on the engine’s rotation and the position of the piston in the barrel.<\/li>\n
                        4. The color of the spark can also indicate the health of the spark plugs, as a blue spark represents a hotter, more effective spark, whereas a red spark represents a cooler, less powerful spark.<\/li>\n<\/ol>\n<\/li>\n<\/ol>\n

                          IV. Discussion on Zen Chapters 7, 8, and 9<\/strong><\/p>\n

                            \n
                          1. Highlighted Concepts\n
                              \n
                            1. Dumb Questions Prevent Dumb Mistakes<\/li>\n
                            2. Inductive vs. Deductive Reasoning<\/li>\n
                            3. The Scientific Method has its place in many facets of life, especially when a difficult problem occurs in motorcycle maintenance.<\/li>\n<\/ol>\n<\/li>\n<\/ol>\n
