CYLINDER HEAD
The cylinder head is made of an aluminum alloy that
is lightweight and offers outstanding cooling effi-
ciency.
The combustion chamber is of the pent-roof type.
The two intake and two exhaust ports are in a cross-
flow arrangement. There is a squish area provided in
the combustion chamber, which promotes turbu-
lence, further mixing of the air-fuel mixture, and more
efficient combustion.
The spark plugs are located at the center of the com-
bustion cambers.
The camshaft bearings are placed at six locations on
the exhaust side.
