A decompression system for a four-cycle engine includes a decompression shaft positioned within a camshaft. The decompression shaft interacts with decompression pins positioned within pin holes formed in the camshaft. In some embodiments, the decompression shaft is formed from a first longitudinal portion and a second longitudinal portion. In other embodiments, the decompression shaft is supported at least in part by a middle portion of a bore that extends through the camshaft.
