Upgrade your M8 engine with the S&S CYCLE 132" Power Package Engine Performance Kit, designed for optimal performance and reliability. This kit transforms the stock 114" or 117" oil-cooled M8 into a powerful 132" engine, providing enhanced horsepower and torque for demanding riding conditions. The kit features an adjustable pressure relief valve that can be fine-tuned with the unit installed in the engine, ensuring optimal oil pressure management during operation. S&S valve springs incorporated in this package utilize a high-performance conical single-wire spring design, which contributes to improved valve stability at high RPMs. The big bore cylinders are precisely matched with a high-performance cam, cam plate, and oil pump, creating a cohesive system that maximizes airflow and fuel combustion efficiency. An integrated magnet in the cam chest helps prevent debris from entering the oil pump, enhancing engine longevity and reducing maintenance needs. The design includes independent scavenge sections for the flywheel cavity and cam chest, which promotes better oil flow and reduces the risk of oil starvation, thereby extending engine life. The kit retains original engine serial numbers and features removable passage plugs for easier servicing, simplifying maintenance tasks. Multi-layered steel (MLS) head gaskets ensure a reliable seal under high-stress conditions, preventing leaks and maintaining compression. Both scavenge pickups are equipped with debris screens, further safeguarding internal components from dirt and debris. The performance is complemented by a matched 550 camshaft that delivers improved power delivery and throttle response. This kit works seamlessly with the stock crankcase and retains the original engine height to preserve your motorcycle's factory appearance and fitment. It includes a cam cover badge for added authenticity and is manufactured in the USA, reflecting quality craftsmanship. Whether you are seeking increased performance or preparing for high-demand riding, this comprehensive engine upgrade offers durability, power, and ease of installation in a single package.
