The BOFO 7EWLIA Cylinder Head Kit is a high-performance upgrade for Honda CRF70, XR70, CT70, C70, TRX70, and 70cc/50cc engines. This cylinder head kit includes all necessary components to replace the stock cylinder head, bringing significant improvements to engine power and overall performance.
Starting with the cylinder head itself, the BOFO kit features a high-flow design. The combustion chamber is engineered to provide optimal swirl and turbulence for a more efficient air-fuel mixture. The multi-angle valve seat design allows for improved sealing and decreased exhaust gas leakage, ensuring a cleaner burn and better combustion efficiency.
The BOFO 7EWLIA Cylinder Head Kit includes high-performance exhaust ports and high-flow intake ports. The exhaust ports have been designed to increase flow rate and reduce exhaust back pressure, enabling increased power output and torque. The intake ports, on the other hand, are designed to enhance the airflow into the engine for superior combustion and improved power delivery.
The kit also includes upgraded valves, which offer increased durability and better valve control. The intake valves are pent-roof shaped with a larger diameter that provides more airflow and better filling for improved combustion efficiency. The exhaust valves are oversized, enabling a larger exhaust port and reducing back pressure for improved performance.
Another significant improvement from the BOFO 7EWLIA Cylinder Head Kit is the inclusion of a high-performance camshaft. The camshaft has been designed to offer improved valve control and better timing for optimal power output. The camshaft is precision-engineered to fit perfectly into your Honda engine and is made of high-strength materials for durability and long-lasting performance.
In addition, the BOFO 7EWLIA Cylinder Head Kit includes high-performance pistons and rings to complete the top end build. The pistons are forged for added strength and durability, while the rings are designed to provide a better seal and reduce friction for improved engine efficiency.
Overall, the BOFO 7EWLIA Cylinder Head Kit is an excellent choice for riders seeking improved performance from their Honda CRF70, XR70, CT70, C70, TRX70, or 70cc/50cc engine. The kit offers numerous upgrades to enhance the engine's power output and overall performance, making it an excellent investment for riders looking to gain an edge on the competition.
