摘要： An arrangement for improving the cooling performance of an engine by suitably arranging an exhaust pipe and a valve mechanism with respect to the inclined direction of a cylinder block. A cylinder block is inclined in the rightward or leftward direction of a vehicle body, and an exhaust pipe and a valve mechanism are disposed along the inclined side wall of the cylinder block. The opposed side wall of the cylinder block, which has a large space in the vertical direction and exerts a large effect on the cooling performance of the engine, is less susceptible to thermal effects from the exhaust pipe and the valve mechanism, to thereby improve the cooling performance of the entire engine.

摘要： A chain guide structure having, in combination, a chain cover and a chain guide member which can easily and securely be placed on the chain cover for temporary assembling, and capable of improving the efficiency of the assembling work. A chain guide structure for guiding a chain wound round a driving sprocket supported on the sidewall of a crankcase and covered with a cover attached to the sidewall includes an elastic chain guide member having a substantially semicircular shape opening toward the rear and supported on the inner surface of the cover so as to extend along the chain. At least two ribs are formed on the inner surface of the cover so as to hold the chain guide member by elastically deforming the chain guide member so that the width of the open end of the chain guide member is changed.

摘要： An intake port and an exhaust port are formed without changing a passage sectional area or its shape a little and without increasing an entire height of an engine. A seat machining part of a valve guide fixing seat of the intake port and the exhaust port are arranged at the cylinder head and are bent in any one of the right side direction or the left side direction as seen from the center of the valve. With such an arrangement, a minimum thickness for the seat machining can be assured, the intake port and the exhaust port do not change the passage sectional area or the sectional shape a little and so it is not necessary to increase the entire height of the engine.

摘要： A shaft having a sprocket fixed at one end thereof is reliably assembled to the supporting wall of an engine, with a reduced number of parts and man-hours required for assembly. A camshaft having a sprocket fixed at one end thereof is installed by engaging a pair of ball bearings with supporting holes on supporting walls of the engine. A crescent-shaped step partially cut in the loosing direction of an endless chain is formed on one supporting hole. An outer race of one ball bearing on the camshaft is engaged with the step. An endless chain is wound around the sprocket, and the one ball bearing is moved into the supporting hole, and the other ball bearing is correctly engaged with the other supporting hole, thereby completing assembly of the camshaft.
