With 3.927\" bore S\u0026amp;S feels this is the largest bore possible that can be safely used with stock bore crankcase spigots. Fits stock 4\" stroke 88\" Big Twin models and increases capacity to 97\". 9.7:1 CR with stock 85cc cylinder heads; 10.3:1 CR with S\u0026amp;S 79cc heads. The forged pistons requires no flywheel re-balancing and valve pockets are enlarged to acommodate oversize valves and higher lift cams. Note: S\u0026amp;S does not recommend boring OEM cylinders to a bore this large because of possible failing of structural integrity. Just one piston oversize (917503) available for this kit.\u003c\/p\u003e\n\u003ch2\u003eFitment\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e99-05 88\" Dyna\u003c\/li\u003e\n\u003cli\u003e99-06 88\" FLT\/Touring\u003c\/li\u003e\n\u003cli\u003e00-06 88\" Softail (NU)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eProduct Details\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e S\u0026amp;S\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e Motor parts \u0026gt; Pistons and rings kits\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit:\u003c\/strong\u003e KIT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct code:\u003c\/strong\u003e 531705\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003ePart Numbers\u003c\/h2\u003e\u003cp\u003eMCS Part Number: 531705\u003cbr\u003eManufacturer Part Number: 910-0205\u003c\/p\u003e","brand":"S\u0026S Cycle","offers":[{"title":"Default Title","offer_id":44334603501888,"sku":"MCS531705","price":1114.27,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1329\/4265\/files\/531705k.jpg?v=1776024123","url":"https:\/\/hogparts.co.uk\/products\/mcs531705","provider":"Hogparts UK Ltd","version":"1.0","type":"link"}
