I originally illustrated from memory the Sears 2-speed minibike I had at age 14. Courtesy of OldMiniBikes members my knowledge was expanded to realize the Sears was
the Comet setup.
Other members soon contributed and it was explained how
the Fairbanks-Morse 2-speed differs, is easier to build, and is better at keeping chain lubricant out of the jackshaft clutch. :thumbsup:
Each phase is illustrated. The F-M illustration includes a side-by-side comparison with the Comet setup on page 4.
