S&S Cycle breather reed valve assemblies improve oil scavenging and reduce oil carryover. Plus, they'll make your bike run better. The steel breather reeds of these valve assemblies are normally closed. As they open and close again during the stroke cycle, a slight vacuum is maintained in the crankcase, greatly improving oil scavenging. Enjoy your riding experience even more after you install S&S Cycle breather reed valve assemblies.

If you're overhauling an older motorcycle engine or building a lubrication system from scratch, consider the turnkey ease of S&S Cycle oil pump kits. They offer the same width oil supply and return gears as a stock Harley-Davidson® aluminum pump, but these driveshaft gears increase potential oil volume delivery by 25 percent over stock on some engines. S&S pumps are machined with an oil pressure bleed-off passage, relieving pressure build-up on top of the valve to maintain consistent oil pressure. Excess oil is also routed directly to the supply side of the pump to reduce the amount returned to the tank—which means less foaming and cavitation. The kits are available for a variety of bikes, including Big Twin models. S&S Cycle oil pump kits include: * Complete oil pump assembly * Pinion shaft pump drive gear * Oil pump driveshaft gear * Breather gear * Mounting hardware * Fittings and gaskets * Instructions

S&S Cycle's 88 in. big bore kits provide significant benefits by increasing the engine displacement, resulting in more power and torque, especially noticeable in the low to mid-range powerband, while generally maintaining the stock engine character and rideability; essentially giving the bike a stronger punch with increased acceleration without drastically altering its feel. The larger bore size allows for more air and fuel to be ingested per combustion cycle, leading to a noticeable boost in power output, particularly in the low and mid-range rpm bands. For riders who frequently haul loads, the increased torque can be beneficial for pulling heavier trailers or carrying extra cargo. Many 88 in. big bore kits are designed to work with mostly stock components, requiring minimal additional engine modifications for installation. Compared to other performance upgrades like high-lift cams or forced induction, a big bore kit is often considered a cost-effective way to significantly increase engine power. After installing a big bore kit, proper engine tuning with adjustments to the fuel injection or carburetor settings is crucial to optimize performance and ensure efficient combustion. Select the S&S Cycle big bore kit specifically designed for your HD® model and year.
