Description

Unlock extreme power and torque with the S&s Cycle 132" Power Package, a comprehensive engine upgrade meticulously engineered for your M8 motorcycle. This kit boasts durable 4.32" bore cylinders paired with high-strength 11.0:1 compression ratio forged pistons, delivering a significant boost in displacement and combustion efficiency. Experience enhanced throttle response and a robust power band across the RPM range.

Beyond raw power, this package integrates an advanced S&S oil pump and cam plate, featuring a striking blue anodized finish. Its innovative design includes independent scavenge sections for both the flywheel cavity and cam chest, ensuring optimal oil evacuation. Debris screens in both scavenge pickups and a magnet in the cam chest actively prevent contaminants from entering the oil pump, safeguarding your engine's longevity. The increased oil flow capacity on both the feed and scavenge sides, coupled with an adjustable pressure relief valve, guarantees superior lubrication and cooling under demanding conditions. Complementing these enhancements are S&S Quickee pushrods, premium tappets, and hard-anodized billet aluminum tappet cuffs, providing a robust and reliable valve train. The included S&S 550 cams are specifically designed for big bore applications, maximizing the potential of the 132" engine. High-performance conical single wire valve springs are engineered to accommodate cams with up to 0.605" lift, ensuring precise valve control. This Made in the USA kit comes complete with exhaust, cylinder base, and head gaskets for a seamless installation.
