Abstract: An engine is disclosed of the V-configuration having an integrated engine and transmission. The engine has an engine ventilation system communicating between the crankcase and an upper end of the valve cover, whereby blow-by gases can be returned to the air intake system to recycle the unspent fuel. The engine also includes an easily accessible/removable cam, such that the camshaft may be removed without removing the rocker arms. The engine also includes a lubrication system for lubricating components of the engine and transmission.
