摘要： A cylinder block, a cylinder head and a cylinder head cover are stacked in order to form a four-cycle engine. A valve train of a single overhead camshaft (SOHC) type provided with an intake valve and an exhaust valve is provided in the cylinder head. A line extending parallel with a joint between the cylinder head and the cylinder head cover is inclined forward and downward toward a line parallel with a joint between the cylinder block and the cylinder head. An axis of an exhaust valve and/or an axis of a plug tube is/are perpendicular to the line extending parallel with the joint between the cylinder head and the cylinder head cover. A cylinder head hanger is integrally formed at an uppermost end of a rear portion of the cylinder head over an intake port.

摘要： An engine for a motorcycle having dummy covers for covering at least part of cylinder heads from the sides and overhead covers for covering at least part of head covers coupled to the cylinder heads from above and the sides. This configuration is provided in order to enhance the functional beauty of the engine wand to eliminate the need to provide specially shaped parts for cylinder heads, or the need provide a special surface treatment for the cylinder heads. At least one spot of dummy covers is fastened to an engine main unit including a cylinder head and a head cover with bolts. A plurality of engaging protrusions provided in overhead covers formed in a shape to cover the bolts are resiliently engaged with the engine main unit or the dummy covers so that the overhead covers are detachable or attachable.
