S&S Cycle 84-99 BT 96in Sidewinder Big Bore Stroker Kit - Natural

When you open this S&S Cycle Sidewinder Big Bore Stroker Kit, you'll find a dynamically balanced S&S flywheel assembly with a 4-5/8 inch stroke and S&S 3-5/8 inch bore high tensile cast iron Sidewinder cylinders. This kit offers an economical way to significantly increase the displacement of your stock 80 cubic inch Harley-Davidson Evolution Big Twin engine, bringing it up to 96 cubic inches. It includes nearly everything you need to complete this engine upgrade.

To install these components, your stock engine cases will need to be bored out to 3-5/8 inches to accommodate the new cylinders. This stroker kit is designed to provide a substantial increase in engine size, which typically translates to more torque and power. The S&S flywheel assembly is dynamically balanced, meaning it's weighted to reduce vibration and ensure smoother operation at higher RPMs. The high tensile cast iron cylinders are built for durability and to handle the increased stresses of a larger displacement engine.

This kit is a significant undertaking for those looking to get more performance out of their Evolution Big Twin. It's important to note that this kit is not CARB approved and cannot be shipped to California. Ensure you have the necessary machining services available for boring the cases before beginning this project.
