124" Hot Set Up® - Big Bore/Stroker - Wrinkle Black - 96/103/110A Twin Cam
Upgrade your Twin Cam engine with the S&S Cycle 124" Hot Set Up® kit, designed specifically for non-balanced models to maximize performance and reliability. This comprehensive assembly allows you to convert your stock engine into a powerful 124 cubic inch powerhouse while maintaining compatibility with your existing stock crankcases. The package includes S&S Super Stock® 91 cc cylinder heads with specially machined manifold mounting surfaces, ensuring a perfect fit with a stock length intake manifold. The 4.125-inch bore cylinders paired with forged big bore flattop pistons deliver increased displacement and improved combustion efficiency, contributing to enhanced horsepower and torque. The S&S 4.625-inch stroke flywheel assembly and 640 gear drive Easy Start cams provide smooth, reliable power delivery, while the premium tappets, adjustable pushrods, and roller rocker arms ensure durability and precise valve operation. All necessary hardware, gaskets, and instructions are included, simplifying installation for experienced builders. Made in the USA, this kit features a striking wrinkle black finish that complements your bike’s aesthetic. Please note that the EFI system must be recalibrated after installation, and fuel or ignition systems are not included. Proper clearance checks and adherence to assembly specifications are essential for optimal performance. Although the increased engine height of 0.960 inches does not interfere with frame clearance, it's recommended to verify fitment, as the engine's modifications allow for a stock EFI throttle body to fit seamlessly due to the specially machined head surfaces. This kit is a perfect choice for riders seeking a significant power upgrade with proven components tailored for Twin Cam models.
