California Restricted

California laws prohibit (in most cases) the use of any aftermarket product whose installation requires the removal of any emissions control related components as regulated by the California Air Resources Board (www.arb.ca.gov).

If an item is designated as "Competition and Racing Vehicles Only", we will require a race waiver be digitally signed before an item can ship to California. If an item is to be exported from California, an export waiver is available as well. This is a REQUIRED guarantee from you that a restricted item will NOT be used on any public highway in California; only on private race tracks in racing or competition use.

The 97" Big Bore Kit by S&S Cycle is designed to deliver significant performance improvements for stock cylinder heads while ensuring easy installation without the need for case boring or splitting. Constructed from premium aluminum castings with cast-in iron liners, the kit includes precision-engineered components such as cylinders, forged coated pistons, rings, and a complete gasket set (head, base, and exhaust). The pistons are designed to match the weight of stock pistons, eliminating the need for flywheel rebalancing. The cylinders are compatible with both stock and S&S Super Stock heads and do not require crankcase machining for installation. The valve pockets in the pistons are enlarged to accommodate oversized valves and higher-lift cams, enhancing performance potential. The kit features a durable wrinkle powder-coated cylinder finish designed to match Harley-Davidson's factory appearance. It is recommended that installation be performed by a skilled technician, with all clearances and assembly specifications thoroughly checked. This kit offers a reliable and straightforward upgrade for riders seeking enhanced engine performance.
