Waist spiral polishing is applied to the valve neck (valve neck diameter: intake side φ4.0, exhaust side φ4.5, stem diameter φ5.5) to reduce intake and exhaust resistance. In addition, soft nitriding surface treatment is applied to strengthen the surface and improve initial fit. We aimed to increase torque by reducing intake resistance, and by making the combustion chamber side flat, we succeeded in achieving high compression. Also, due to the significant weight reduction, vibration mass is reduced. Powerfully revs up to high rpm. Caution (Disclaimer) > Please read 4990852012183
