Upgrade your M8 engine with the S&S Cycle 132" Power Package Engine Performance Kit, designed for chain drive and oil-cooled systems. This comprehensive kit transforms 114" or 117" oil-cooled M8 engines into a robust 132" displacement, delivering increased power and performance. The kit features an adjustable pressure relief valve that can be fine-tuned with the unit installed in the engine, ensuring optimal operation under various conditions. S&S valve springs utilize a high-performance conical single-wire spring design, providing improved durability and valve control during aggressive riding. The big bore cylinders are precisely matched with a performance cam, cam plate, and oil pump, ensuring seamless integration and reliable operation. A magnet located in the cam chest helps prevent debris from entering the oil pump, enhancing engine longevity. The design incorporates independent scavenge sections for the flywheel cavity and cam chest, facilitating efficient oil flow and easier maintenance. Original engine serial numbers are retained to preserve your engine’s identity, while removable passage plugs allow for straightforward servicing. The kit includes MLS (multi-layered steel) head gaskets, which ensure reliable sealing and durability under high-performance conditions. Both scavenge pickups are equipped with debris screens, adding an extra layer of protection against contaminants. The performance camshaft is a matched 550 profile, optimized for increased airflow and power output. This engine kit works seamlessly with stock crankcases and maintains the original engine height for compatibility. Additionally, the package includes a cam cover badge and is proudly made in the USA, reflecting quality craftsmanship. Ideal for riders seeking to enhance their M8 engine’s performance with a reliable, high-quality upgrade, this kit offers a straightforward installation process and long-lasting results for your motorcycle.
