Review ATHENA Complete 47.66mm Hyper Cylinder Race Kit Bore Bigbore Yamaha 70cc

The P400485105001 Athena Race Kit for Yamaha 70cc Big Bore engines is a comprehensive upgrade kit designed to enhance the performance of your Yamaha engine. This kit includes a 47.66mm hyper CW50 cylinder, which is larger than the standard cylinder, allowing for increased combustion volume, resulting in more power and torque.

The cylinder is made of high-quality aluminum alloy, ensuring lightweight yet robust construction. It features a CW50 bore, which is larger than the standard CW40 bore, allowing for a larger combustion chamber and consequently, more air-fuel mixture to be burned, thereby increasing the engine's power output.

The kit also includes a piston and rings, which are crucial components in the engine's combustion process. The piston is made of forged aluminum, ensuring strength and durability. The rings, on the other hand, are designed to seal the combustion chamber, preventing leakage and ensuring optimal engine performance.

The Athena Race Kit also includes a high-compression piston head, which allows for a higher compression ratio, further increasing the engine's power output. The kit also includes a high-performance carburetor, which allows for more air-fuel mixture to be delivered to the engine, resulting in improved performance.

In addition, the kit includes a high-performance crankshaft, which is designed to handle the increased power output of the engine. The crankshaft is made of high-strength steel and features a balanced design, ensuring smooth and reliable operation.

The Athena Race Kit is an excellent upgrade for anyone looking to increase the performance of their Yamaha 70cc Big Bore engine. It is easy to install and comes with clear installation instructions, ensuring a hassle-free upgrade process. With this kit, you can expect increased power, torque, and overall engine performance, making your Yamaha 70cc Big Bore engine more fun to ride.
