3. DESCRIPTION (figs. [1], [2], and [3]).
a. This 2‐cylinder solo motorcycle is powered by a V‐type, air‐cooled gasoline engine, operating on conventional 4‐stroke, 4‐cycle principles. Air‐cooled engines rely upon movement of air over cylinder and head radiating fins, and upon circulation of oil for dissipation of excessive heat. Motorcycle engines, therefore, under no conditions should be operated for more than 1 minute when motorcycle is not in motion.
