CYLINDER HEAD/VALVE TRAIN

4–VALVE
The cylinder head is made of an aluminum alloy that is lightweight and has excellent heat radiating properties and uses
a cross–flow system in the layout of the air intake valves. The combustion chambers have improved combustion
efficiency by using a center–plug type pentroof form.
The valve driving system is a rocker arm system using a seesaw type for the intake side and a cantilever type for the
exhaust side.
Valve clearance is adjusted by adjusting screw on both intake and exhaust.
