Piston set has a compression of 9.6:1 and includes rings.\n\u003cp\u003eThe Keith Black KB305.STD 80 inch Evolution Piston Kit Standard features a hypereutectic alloy piston cast in a permanent steel mold. This manufacturing process supports a lightweight piston design intended to help produce more power, use less fuel and provide extended service life. The piston is standard size for a 3.498-inch bore and has a 9.5:1 compression ratio.\u003c\/p\u003e\u003cp\u003eThe alloy’s low heat transfer helps keep the skirts cooler, minimizing piston expansion. Combined with high compression ring placement, this design is intended to increase power and economy. High ring placement also helps reduce detonation and increase top-ring temperature. The kit is supplied as a set and is associated with 80 inch Evolution applications, including 1984–1993 Harley-Davidson FXR models as specified by the supplier.\u003c\/p\u003e\u003cp\u003eKeith Black recommends running the engine at moderate speeds for at least 500 miles while avoiding excessive operation in lower gears to properly break in new pistons and rings. Refer to the manufacturer’s fitment and installation guide for application-specific details. Suggested and accessory items include the 11-1363 80 inch Shovelhead Piston Ring Set Standard, 16-0622 Ring-O-Matic Ring Compressor Tool Kit, 60-0167 and 16-0075 Wrist Pin Ring Tool.\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.STD\u003c\/li\u003e\n\u003cli\u003ePiston Type: 80 inch Evolution Piston Kit Standard\u003c\/li\u003e\n\u003cli\u003eMaterial: Hypereutectic alloy\u003c\/li\u003e\n\u003cli\u003eBore Size: Standard size for a 3.498-inch bore\u003c\/li\u003e\n\u003cli\u003eCompression Ratio: 9.5:1\u003c\/li\u003e\n\u003cli\u003eDesign: Low heat transfer alloy with high compression ring placement\u003c\/li\u003e\n\u003cli\u003eQuantity: Supplied as a set\u003c\/li\u003e\n\u003cli\u003eFitment: 1984–1993 Harley-Davidson FXR models as specified by the supplier\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":44583382843479,"sku":"11-2257","price":384.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0556\/2276\/2583\/files\/11-2257.jpg?v=1793267641","url":"https:\/\/valleyspeed.net\/en-gb\/products\/keith-black-kb305-std-80-inch-evolution-piston-kit-standard","provider":"The Speed Shop Canada","version":"1.0","type":"link"}
