Rebuilt 500cc Royal Enfield engine. Complete with magneto and dynamo. Carburetor is original, some wear but functional. All new bottom and top end, the magneto fires a hot spark for the ignition and the 6 volt dynamo will run the lights. The oil tank is integral to the bottom end and oil pump is in excellent shape. The twin exhaust port only has one exhaust valve and was designed that way for appearances. ( Rather novel ) . A great replacement engine for a rare machine or a unique unit for a custom build. Located in Ladysmith, BC. Will ship at buyers expense.
