CYLINDER HEAD

Structure
• The cylinder head is made of a high heat conductive, lightweight aluminum alloy, which has been quenched.
• Compact, pentroof-type combustion chambers have been adopted. The spark plugs are mounted at the top of
the combustion chambers to improve combustion efficiency.
• The intake/ehaust port layout is a cross flow type, (the angle between two valves is 39°, the two intake valves
and the two ehaust valves per cylinder) which improves air intake/ehaust efficiency.
• The cylinder head bolt is a plastic region tightening bolt, which is tightened in five motions. It insures a stable
ais during tightening.
