This piston kit features a 3.5-inch bore, 9:1 compression, and compatibility with a 3.812-inch stroke and a dish head, as stated by the manufacturer.\u003c\/p\u003e\u003cp\u003eThe pistons are alloy cast in a permanent steel mold to provide a lightweight design. The alloy's low heat transfer helps keep the skirts cooler and minimizes piston expansion. The piston set includes a Hastings Moly ring set. Use ring end gap instructions to help avoid ring butting; the second ring end gaps do not require extra clearance.\u003c\/p\u003e\u003cp\u003eFor proper break-in, run the engine at moderate speeds for at least 500 miles and avoid excessive operation in lower gears. For 2009 and newer XL 883 applications, the existing cylinders cannot be overbored to 1200cc; separate 1200cc cylinders are required for those applications. Refer to the manufacturer's fitment and installation information before assembly.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eBrand and Part Number: Keith Black KB272.005 piston set\u003c\/li\u003e\n\u003cli\u003eApplication: 883cc conversion piston set for specified 1986-1995 Harley-Davidson XL models\u003c\/li\u003e\n\u003cli\u003eBore: 3.5 inches\u003c\/li\u003e\n\u003cli\u003eCompression: 9:1\u003c\/li\u003e\n\u003cli\u003eStroke and Head: Designed for use with a 3.812-inch stroke and a dish head\u003c\/li\u003e\n\u003cli\u003eConstruction: Alloy cast in a permanent steel mold\u003c\/li\u003e\n\u003cli\u003eIncluded Rings: Hastings Moly ring set\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\u003eTechnical Note: Follow ring end gap instructions to avoid ring butting; second ring end gaps do not need extra clearance\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":44583427244119,"sku":"11-2229","price":409.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0556\/2276\/2583\/files\/11-2229.jpg?v=1793268367","url":"https:\/\/valleyspeed.net\/en-gb\/products\/keith-black-kb272-005-883cc-conversion-piston-set-005-oversize","provider":"The Speed Shop Canada","version":"1.0","type":"link"}
