The S&S Cycle 132" Power Package Engine Performance Kit (Part #310-1238) is designed to significantly enhance the performance of your M8 engine. This comprehensive kit transforms either the 114" or 117" oil-cooled M8 engine into a powerful 132" engine, providing increased displacement and improved horsepower. The kit features a high-performance gear drive system and includes highlighted fin design for efficient cooling and a distinctive aesthetic. Built in the USA, this performance upgrade maintains the stock engine height for straightforward installation and compatibility. The kit includes a variety of precision-engineered components to optimize engine operation and durability, ensuring reliable power delivery. An adjustable pressure relief valve is integrated into the unit, allowing fine-tuning directly on the engine for optimal performance. S&S valve springs feature a conical single-wire design that enhances valve control at high RPMs, contributing to overall engine stability and longevity. The big bore cylinders are carefully matched with a performance cam and cam plate, along with an oil pump, to maximize airflow and combustion efficiency. A magnet in the cam chest helps prevent debris from entering the oil pump, protecting vital engine components. Independent scavenge sections for the flywheel cavity and cam chest facilitate thorough oil management and maintenance. The kit retains the original engine serial number for proper identification and includes removable passage plugs for easier servicing. Multi-layered steel (MLS) head gaskets ensure a reliable seal under high-pressure conditions, while debris screens in both scavenge pickups further protect the oil system. The included 550 cam is tuned for optimal performance and power output. The kit also features a stylish cam cover badge, adding a custom touch to your engine. Designed to work seamlessly with stock crankcases, this performance package is an ideal upgrade for riders seeking increased power and reliability from their M8 engine.
