The S&S 98" Big Bore Kit offers a straightforward solution for significantly increasing engine displacement without requiring extensive machining or case modifications. This kit is designed for easy installation, allowing you to swap out the cylinders while maintaining the stock engine height. It includes premium aluminum cylinders with cast-in iron liners, pistons, rings, and all necessary gaskets (head, base, and exhaust). The 11-fin cylinder design mirrors the original equipment manufacturer's (OEM) shape and comes prefinished for hassle-free installation. The increased fin area improves heat dissipation for better engine cooling. The centrifugal cast, gray iron liner boasts a tensile strength of 40,000 psi, providing exceptional durability and wear resistance. CP Pistons included in the kit enhance performance, minimize noise, and ensure long-lasting operation. This kit features the largest bore size (3.937") that can be installed in a stock engine case, maximizing performance while maintaining the original engine geometry. It requires professional assembly to ensure proper clearances and specifications are met. Perfect for riders seeking a reliable, high-performance upgrade for their motorcycle.
