The Omnivore is a two-stroke direct-injected engine designed to take advantage of the latest in electronic engine management and run on just about any liquid fuel (hence the name).

The Omnivore is a flex fuel engine that is designed to extract the maximum amount of work regardless of what type of fuel is used.
