The engine features single or optional dual ignition, reed valve induction, free air cooling, tuned exhaust system, a single slide venturi-type Bing carburetor, fuel pump, Nikasil cylinder coatings. The engine was offered with a gearbox reduction system that included a one way clutch. Starting is electric starter with no provision for a recoil starter.[1]
