Description

The S&S Cycle 132" Big Bore Kit is a direct bolt-on solution designed to elevate your M8 engine's capabilities, boosting displacement to a massive 132". This kit features robust 4.320" big bore cylinders paired with high-strength 11.0:1 forged pistons, ensuring exceptional compression and durability for demanding riding. At its core is the high-performance HPT496 cam, specifically engineered for big bore applications to deliver optimal power and torque across the RPM range. The integrated S&S oil pump and cam plate system provides superior lubrication and cooling, incorporating independent scavenge sections for the flywheel cavity and cam chest, debris screens in both pickups, and a magnet in the cam chest to prevent contaminants from reaching the pump. An adjustable pressure relief valve allows for fine-tuning even after installation, optimizing oil flow. This kit also includes S&S Quickee pushrods with chrome pushrod tubes, premium tappets, and hard-anodized, billet aluminum tappet cuffs for a robust valvetrain. High-performance conical single wire S&S valve springs are included, compatible with cams up to 0.605" lift, ensuring reliable valve control. A multi-layered steel (MLS) head gasket provides a dependable seal. Designed for seamless integration, this performance kit retains stock engine height, works perfectly with stock crankcases and both stock and S&S roller rocker arms, and preserves your original engine serial numbers. Proudly Made in the USA, it’s a complete upgrade for serious M8 enthusiasts.
