Decompression system for engine

Abstract

A push rod operated multi-valve V-type engine particularly adapted for use in motorcycles or like vehicles and which engine is air cooled. The engine employs a very simplified construction and overhead valve actuating mechanism utilizing push rods. The push rods are contained within push rod tubes formed at one side of the engine that provide a neat appearance and ease of servicing without adversely affecting the air cooling. A composite cylinder head construction is employed, as well as an improved lubricating system for the pair of driven camshafts. Furthermore, a decompression system is incorporated in the valve actuating mechanism to lower the compression ratio so as to facilitate starting.
