Piston set has a compression of 10.6:1 and includes rings.\n\u003cp\u003eUpgrade your Harley Davidson Twin Cam engine with the Keith Black 11-2273 piston set, designed specifically for models ranging from 1999 to 2006. Crafted with the advanced hypereutectic alloy, these pistons are cast in a permanent steel mold, ensuring a lightweight yet durable construction that enhances engine performance while reducing fuel consumption. The.030 oversize pistons are engineered to fit a 3-3\/4 inch bore, optimized for high compression ratios and increased power output. The 10.6:1 compression ratio promotes better combustion efficiency, resulting in more torque and improved fuel economy. The unique low heat transfer properties of the alloy help keep the piston skirts cooler, minimizing expansion and wear, which extends the lifespan of the components. The high ring placement further reduces detonation risks and elevates the top ring temperature, contributing to engine stability at higher RPMs. Proper break-in is essential for optimal performance; run the engine at moderate speeds for at least 500 miles, avoiding excessive operation in lower gears to ensure proper seating of the rings and piston surfaces. For detailed installation instructions, refer to the provided link. This piston set includes all necessary components and is compatible with a variety of Harley Davidson FXST and FLST models, making it an ideal choice for engine rebuilds or performance upgrades. Enhance your motorcycle’s power, efficiency, and longevity with this high-quality piston set from Keith Black.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\n\u003cul\u003e\u003cli\u003eHypereutectic alloy construction for durability and lightweight performance\u003c\/li\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003cli\u003eCast in a permanent steel mold for consistent quality\u003c\/li\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003cli\u003eOversize:.030 for a 3-3\/4 inch bore, ideal for engine rebuilds\u003c\/li\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003cli\u003eCompression ratio: 10.6:1 for increased power and efficiency\u003c\/li\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003cli\u003eLow heat transfer alloy keeps piston skirts cool, reducing expansion\u003c\/li\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003cli\u003eHigh ring placement minimizes detonation and improves top ring temperature\u003c\/li\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003cli\u003eEngine compatibility: fits Harley Davidson FXST and FLST models from 1999-2006\u003c\/li\u003e\u003c\/ul\u003e\n\u003cbr\u003e\nFitment:\u003cbr\u003e\nHarley Davidson FLST 1999\u003cbr\u003e\nHarley Davidson FLST 2000\u003cbr\u003e\nHarley Davidson FLST 2001\u003cbr\u003e\nHarley Davidson FLST 2002\u003cbr\u003e\nHarley Davidson FLST 2003\u003cbr\u003e\nHarley Davidson FLST 2004\u003cbr\u003e\nHarley Davidson FLST 2005\u003cbr\u003e\nHarley Davidson FLST 2006\u003cbr\u003e\nHarley Davidson FLT 1999\u003cbr\u003e\nHarley Davidson FLT 2000\u003cbr\u003e\nHarley Davidson FLT 2001\u003cbr\u003e\nHarley Davidson FLT 2002\u003cbr\u003e\nHarley Davidson FLT 2003\u003cbr\u003e\nHarley Davidson FLT 2004\u003cbr\u003e\nHarley Davidson FLT 2005\u003cbr\u003e\nHarley Davidson FLT 2006\u003cbr\u003e\nHarley Davidson FXD 1999\u003cbr\u003e\nHarley Davidson FXD 2000\u003cbr\u003e\nHarley Davidson FXD 2001\u003cbr\u003e\nHarley Davidson FXD 2002\u003cbr\u003e\nHarley Davidson FXD 2003\u003cbr\u003e\nHarley Davidson FXD 2004\u003cbr\u003e\nHarley Davidson FXD 2005\u003cbr\u003e\nHarley Davidson FXD 2006\u003cbr\u003e\nHarley Davidson FXST 1999\u003cbr\u003e\nHarley Davidson FXST 2000\u003cbr\u003e\nHarley Davidson FXST 2001\u003cbr\u003e\nHarley Davidson FXST 2002\u003cbr\u003e\nHarley Davidson FXST 2003\u003cbr\u003e\nHarley Davidson FXST 2004\u003cbr\u003e\nHarley Davidson FXST 2005\u003cbr\u003e\nHarley Davidson FXST 2006\u003c\/div\u003e","brand":"Keith Black","offers":[{"title":"Default Title","offer_id":44653073006634,"sku":"11-2273","price":191.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0692\/2285\/8794\/files\/11-2273.jpg?v=1785884626","url":"https:\/\/atticusgoods.com\/products\/keith-black-11-2273-88-inch-twin-cam-piston-set-030-for-harley-davidson-fxst-and-flst-models","provider":"Atticus Goods","version":"1.0","type":"link"}
