A new 4-5\/8” crankshaft adds a ¼” more stroke, while new stress-relieved cylinders add an 1\/8” more to the bore. Our Red Shift 657 cams are perfectly matched with the heads and piston to provide big torque \u0026amp; HP across the entire RPM range. Red Shift Dual-Piston cam tensioners are included with Pro-Taper pushrods and EZ-Adjust covers for a stable valve train, with all the gaskets needed for assembly. Case boring required for 4-1\/8” cylinders; Timken® bearing conversion and cam chest\/oil system upgrade highly recommended to improve durability and reliability. \u003c\/span\u003e\u003cstrong\u003e\u003cem\u003eMake your\u003c\/em\u003e\u003cspan\u003e \u003c\/span\u003eCVO run even faster than it looks!\u003c\/strong\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv aria-label=\"4 \/ 4\" role=\"group\" class=\"swiper-slide images woocommerce-product-gallery woocommerce-product-gallery__wrapper\"\u003e\n\u003cdiv class=\"woocommerce-product-gallery__image\" data-thumb=\"\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv aria-disabled=\"true\" aria-controls=\"swiper-wrapper-f1e404107ff87f886\" aria-label=\"Previous slide\" role=\"button\" class=\"swiper-custom-left swiper-button-prev-swiper-unique-id-0 swiper-button-disabled\" tabindex=\"-1\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cspan aria-atomic=\"true\" aria-live=\"assertive\" class=\"swiper-notification\"\u003e\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv id=\"swiper-unique-id-1\" data-spacebetween=\"10\" data-clickedslide=\"1\" data-slides-per-view=\"4\" data-lt-slides=\"4\" data-md-slides=\"4\" data-sm-slides=\"4\" data-xs-slides=\"3\" data-breakpoints=\"1\" class=\"swiper-container swiper-control-bottom columns-3 no-arrows slider swiper-swiper-unique-id-1 initialized swiper-container-initialized swiper-container-horizontal second-initialized\"\u003e\n\u003cdiv class=\"et-loader\"\u003e\u003csvg height=\"30\" width=\"30\" viewbox=\"25 25 50 50\" class=\"loader-circular\"\u003e\u003ccircle stroke-miterlimit=\"10\" stroke-width=\"2\" fill=\"none\" r=\"20\" cy=\"50\" cx=\"50\" class=\"loader-path\"\u003e\u003c\/circle\u003e\u003c\/svg\u003e\u003c\/div\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cspan aria-atomic=\"true\" aria-live=\"assertive\" class=\"swiper-notification\"\u003e\u003c\/span\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"col-lg-6 col-md-6 col-sm-12 product-information\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e","brand":"ZIPPERS","offers":[{"title":"BLACK \/ TC A TOURING DYNA","offer_id":42501578293335,"sku":null,"price":12599.95,"currency_code":"CAD","in_stock":true},{"title":"BLACK \/ TC B SOFTAILS","offer_id":42501579538519,"sku":null,"price":12599.95,"currency_code":"CAD","in_stock":true},{"title":"CHROME \/ TC A TOURING DYNA","offer_id":42501578326103,"sku":null,"price":12599.95,"currency_code":"CAD","in_stock":true},{"title":"CHROME \/ TC B SOFTAILS","offer_id":42501579571287,"sku":null,"price":12599.95,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0556\/2276\/2583\/files\/ZIP_124_CVO.jpg?v=1769652565","url":"https:\/\/valleyspeed.net\/products\/zippers-performance-113-cvo-muscle-big-bore-kit-harley-tc-07-17-copy","provider":"The Speed Shop Canada","version":"1.0","type":"link"}
