Piston set has a compression of 9.6:1 and includes rings.\n\u003cp\u003eThe Keith Black KB305.020 80-inch Evolution Piston Kit features a .020-inch oversize piston designed for a 3.498-inch bore and a 9.5:1 compression ratio. The piston uses a hypereutectic alloy cast in a permanent steel mold, supporting a lightweight design intended to help produce more power, use less fuel, and provide extended service life.\u003c\/p\u003e\u003cp\u003eIts low-heat-transfer alloy helps keep the skirts cooler and minimizes piston expansion. Combined with high compression ring placement, this design supports increased power and economy. The high ring placement also helps reduce detonation and raises the top ring temperature.\u003c\/p\u003e\u003cp\u003eThis kit fits 1984–1993 Harley-Davidson FXR models. New pistons and rings should be broken in by running the engine at moderate speeds for at least 500 miles while avoiding excessive operation in lower gears. The product data lists the unit of measure as a set and identifies Mexico as the country of origin. Keith Black part number KB305.020 is included for product identification.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eBrand: Keith Black\u003c\/li\u003e\n\u003cli\u003ePart Number: KB305.020\u003c\/li\u003e\n\u003cli\u003eApplication: 80-inch Evolution piston kit\u003c\/li\u003e\n\u003cli\u003eOversize: .020-inch oversize\u003c\/li\u003e\n\u003cli\u003eBore: Designed for a 3.498-inch bore\u003c\/li\u003e\n\u003cli\u003eCompression Ratio: 9.5:1\u003c\/li\u003e\n\u003cli\u003eMaterial: Hypereutectic alloy\u003c\/li\u003e\n\u003cli\u003eConstruction: Cast in a permanent steel mold\u003c\/li\u003e\n\u003cli\u003eDesign: Low-heat-transfer alloy helps minimize piston expansion\u003c\/li\u003e\n\u003cli\u003eRing Placement: High compression ring placement\u003c\/li\u003e\n\u003cli\u003eFitment: 1984–1993 Harley-Davidson FXR models\u003c\/li\u003e\n\u003cli\u003eBreak-In: Run at moderate speeds for at least 500 miles and avoid excessive operation in lower gears\u003c\/li\u003e\n\u003cli\u003eAccessory Items: 16-0622 - Ring-O-Matic Ring Compressor Tool Kit, 60-0167, 16-0075 - Wrist Pin Ring Tool\u003c\/li\u003e\n\u003c\/ul\u003e\u003cbr\u003e\nFitment:\u003cbr\u003e\nHarley Davidson FLST  1986\u003cbr\u003e\nHarley Davidson FLST  1987\u003cbr\u003e\nHarley Davidson FLST  1988\u003cbr\u003e\nHarley Davidson FLST  1989\u003cbr\u003e\nHarley Davidson FLST  1990\u003cbr\u003e\nHarley Davidson FLST  1991\u003cbr\u003e\nHarley Davidson FLST  1992\u003cbr\u003e\nHarley Davidson FLST  1993\u003cbr\u003e\nHarley Davidson FLST  1994\u003cbr\u003e\nHarley Davidson FLST  1995\u003cbr\u003e\nHarley Davidson FLST  1996\u003cbr\u003e\nHarley Davidson FLST  1997\u003cbr\u003e\nHarley Davidson FLST  1998\u003cbr\u003e\nHarley Davidson FLT  1984\u003cbr\u003e\nHarley Davidson FLT  1985\u003cbr\u003e\nHarley Davidson FLT  1986\u003cbr\u003e\nHarley Davidson FLT  1987\u003cbr\u003e\nHarley Davidson FLT  1988\u003cbr\u003e\nHarley Davidson FLT  1989\u003cbr\u003e\nHarley Davidson FLT  1990\u003cbr\u003e\nHarley Davidson FLT  1991\u003cbr\u003e\nHarley Davidson FLT  1992\u003cbr\u003e\nHarley Davidson FLT  1993\u003cbr\u003e\nHarley Davidson FLT  1994\u003cbr\u003e\nHarley Davidson FLT  1995\u003cbr\u003e\nHarley Davidson FLT  1996\u003cbr\u003e\nHarley Davidson FLT  1997\u003cbr\u003e\nHarley Davidson FLT  1998\u003cbr\u003e\nHarley Davidson FXD  1991\u003cbr\u003e\nHarley Davidson FXD  1992\u003cbr\u003e\nHarley Davidson FXD  1993\u003cbr\u003e\nHarley Davidson FXD  1994\u003cbr\u003e\nHarley Davidson FXD  1995\u003cbr\u003e\nHarley Davidson FXD  1996\u003cbr\u003e\nHarley Davidson FXD  1997\u003cbr\u003e\nHarley Davidson FXD  1998\u003cbr\u003e\nHarley Davidson FXR  1984\u003cbr\u003e\nHarley Davidson FXR  1985\u003cbr\u003e\nHarley Davidson FXR  1986\u003cbr\u003e\nHarley Davidson FXR  1987\u003cbr\u003e\nHarley Davidson FXR  1988\u003cbr\u003e\nHarley Davidson FXR  1989\u003cbr\u003e\nHarley Davidson FXR  1990\u003cbr\u003e\nHarley Davidson FXR  1991\u003cbr\u003e\nHarley Davidson FXR  1992\u003cbr\u003e\nHarley Davidson FXR  1993\u003cbr\u003e\nHarley Davidson FXR  1994\u003cbr\u003e\nHarley Davidson FXST  1984\u003cbr\u003e\nHarley Davidson FXST  1985\u003cbr\u003e\nHarley Davidson FXST  1986\u003cbr\u003e\nHarley Davidson FXST  1987\u003cbr\u003e\nHarley Davidson FXST  1988\u003cbr\u003e\nHarley Davidson FXST  1989\u003cbr\u003e\nHarley Davidson FXST  1990\u003cbr\u003e\nHarley Davidson FXST  1991\u003cbr\u003e\nHarley Davidson FXST  1992\u003cbr\u003e\nHarley Davidson FXST  1993\u003cbr\u003e\nHarley Davidson FXST  1994\u003cbr\u003e\nHarley Davidson FXST  1995\u003cbr\u003e\nHarley Davidson FXST  1996\u003cbr\u003e\nHarley Davidson FXST  1997\u003cbr\u003e\nHarley Davidson FXST  1998","brand":"Keith Black","offers":[{"title":"Default Title","offer_id":44583372619863,"sku":"11-2260","price":779.0,"currency_code":"AUD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0556\/2276\/2583\/files\/11-2260.jpg?v=1793267507","url":"https:\/\/valleyspeed.net\/en-au\/products\/keith-black-kb305-020-80-inch-evolution-piston-kit-020-oversize","provider":"The Speed Shop Canada","version":"1.0","type":"link"}
