Description
West spiral polished valve neck (stem diameter Φ5.5, valve neck diameter intake side Φ4.0, exhaust side Φ4.5) to reduce intake and exhaust resistance.The diameter of the face is enlarged to 24 on the intake side and 20.5 on the exhaust side, which improves the volumetric efficiency of the combustion chamber and realizes higher output and promotes higher rpm.The face is made of stainless steel and the stem is friction-welded with special heat-resistant steel to increase strength.The torque is increased by reducing the intake air resistance, and the combustion chamber side is flattened, resulting in higher compression.In addition, a significant weight reduction reduces vibration mass, and the engine blows powerfully up to the high RPM range.
