The Heath Aircraft Company converted four-cylinder air-cooled Henderson motorcycle engines to power their Parasol monoplanes. Necessary improvement for flight conditions were made in the lubrication system included a larger crankcase and stronger valves.
Many of the early homebuilt aircraft employed engines converted from inexpensive motorcycle and automobile engines.
