The Italkit nickel-silicon cylinder features an advanced design with redesigned ports and an optimized exhaust venturi to increase the revolutions and power of the engine.

Although the exhaust valve system maintains the original design, it is important to note that the valve is not included with the cylinder, so it will be necessary to reuse the original part. This design ensures seamless integration and maintains the efficiency of the gas flow in the engine.
