Outline of system

The offset crank shaft is used, in which the crankshaft centerline is offset by 10.0 mm (0.39 in) from
the cylinder centerline.
The long intake manifold made from plastic is used for higher intake efficiency to obtain higher out-
put power.
The larger intake silencer is useful to suppress the noise.
