S&S Cycle 98 in. Big Bore Cylinder Kits

The S&S Cycle 98 in. big bore cylinder kits for a Harley-Davidson® motorcycle can provide significant benefits, especially for riders seeking more acceleration and pulling power. The larger cylinder bore can dramatically increase engine displacement, resulting in a noticeable boost in horsepower and torque, particularly in the low and mid-range power bands, making for a more powerful and responsive ride, while often still maintaining compatibility with stock cylinder heads and requiring minimal modifications for installation. Many big bore kits are designed as "bolt-on" options; meaning they can be installed without extensive modifications to the existing engine, making them a popular choice for Harley® enthusiasts. To maximize the benefits of a big bore kit, it is often recommended to upgrade other engine components like the camshaft and intake system to optimize airflow and further enhance performance. After the big bore kit install, proper tuning with adjustments to fuel injection settings, as well as the ignition timing may be necessary.
