{"product_id":"keith-black-kb272-std-883cc-conversion-piston-set-standard-size","title":"Keith Black KB272.STD 883cc Conversion Piston Set, Standard Size","description":"Keith Black dish piston set is standard size with a 10.0:1 compression ratio for 1986-up XL Evolution models.\n\u003cp\u003eThe Keith Black KB272.STD 883cc Conversion Piston Set features a hypereutectic alloy cast in a permanent steel mold. This construction supports a lightweight piston design intended to help produce more power, improve fuel economy, and promote extended service life. The standard-size pistons are designed for a 3.498-inch bore and feature a 9:1 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, the design is intended to increase power and economy while reducing detonation and increasing top ring temperature. This set fits 1986–1995 Harley-Davidson XL applications.\u003c\/p\u003e\u003cp\u003eFor 2009-and-newer XL 883 cylinders, the cylinders cannot be overbored to 1200cc. These applications require separately purchased 1200cc cylinders for use with the piston kit. During installation, run the engine at moderate speeds for at least 500 miles and avoid excessive operation in lower gears to properly break in the new pistons and rings. Refer to the manufacturer's fitment guide for installation information.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eBrand and Part Number: Keith Black KB272.STD\u003c\/li\u003e\n\u003cli\u003eProduct Type: 883cc conversion piston set\u003c\/li\u003e\n\u003cli\u003ePiston Material: Hypereutectic alloy cast in a permanent steel mold\u003c\/li\u003e\n\u003cli\u003eBore Size: Standard size for a 3.498-inch bore\u003c\/li\u003e\n\u003cli\u003eCompression Ratio: 9:1\u003c\/li\u003e\n\u003cli\u003eDesign: Low-heat-transfer alloy with high compression ring placement\u003c\/li\u003e\n\u003cli\u003eFitment: 1986–1995 Harley-Davidson XL applications\u003c\/li\u003e\n\u003cli\u003e2009-and-Newer Applications: XL 883 cylinders cannot be overbored to 1200cc and require separately purchased 1200cc cylinders\u003c\/li\u003e\n\u003cli\u003eBreak-In Guidance: Run at moderate speeds for at least 500 miles and avoid excessive operation in lower gears\u003c\/li\u003e\n\u003c\/ul\u003e\u003cbr\u003e\nFitment:\u003cbr\u003e\nHarley Davidson XL  1986\u003cbr\u003e\nHarley Davidson XL  1987\u003cbr\u003e\nHarley Davidson XL  1988\u003cbr\u003e\nHarley Davidson XL  1989\u003cbr\u003e\nHarley Davidson XL  1990\u003cbr\u003e\nHarley Davidson XL  1991\u003cbr\u003e\nHarley Davidson XL  1992\u003cbr\u003e\nHarley Davidson XL  1993\u003cbr\u003e\nHarley Davidson XL  1994\u003cbr\u003e\nHarley Davidson XL  1995\u003cbr\u003e\nHarley Davidson XL  1996\u003cbr\u003e\nHarley Davidson XL  1997\u003cbr\u003e\nHarley Davidson XL  1998\u003cbr\u003e\nHarley Davidson XL  1999\u003cbr\u003e\nHarley Davidson XL  2000\u003cbr\u003e\nHarley Davidson XL  2001\u003cbr\u003e\nHarley Davidson XL  2002\u003cbr\u003e\nHarley Davidson XL  2003\u003cbr\u003e\nHarley Davidson XL  2004\u003cbr\u003e\nHarley Davidson XL  2005\u003cbr\u003e\nHarley Davidson XL  2006\u003cbr\u003e\nHarley Davidson XL  2007\u003cbr\u003e\nHarley Davidson XL  2008\u003cbr\u003e\nHarley Davidson XL  2009\u003cbr\u003e\nHarley Davidson XL  2010\u003cbr\u003e\nHarley Davidson XL  2011\u003cbr\u003e\nHarley Davidson XL  2012\u003cbr\u003e\nHarley Davidson XL  2013\u003cbr\u003e\nHarley Davidson XL  2014\u003cbr\u003e\nHarley Davidson XL  2015\u003cbr\u003e\nHarley Davidson XL  2016\u003cbr\u003e\nHarley Davidson XL  2017\u003cbr\u003e\nHarley Davidson XL  2018\u003cbr\u003e\nHarley Davidson XL  2019\u003cbr\u003e\nHarley Davidson XL  2020\u003cbr\u003e\nHarley Davidson XL  2021\u003cbr\u003e\nHarley Davidson XL  2022\u003cbr\u003e\nHarley Davidson XL  2023\u003cbr\u003e\nHarley Davidson XL  2024\u003cbr\u003e\nHarley Davidson XL  2025\u003cbr\u003e\nHarley Davidson XL  2026","brand":"Keith Black","offers":[{"title":"Default Title","offer_id":44583429144663,"sku":"11-2228","price":779.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0556\/2276\/2583\/files\/11-2228.jpg?v=1793268412","url":"https:\/\/valleyspeed.net\/en-au\/products\/keith-black-kb272-std-883cc-conversion-piston-set-standard-size","provider":"The Speed Shop Canada","version":"1.0","type":"link"}
