This innovative kit transforms your 107\" Milwaukee-Eight engine into a commanding 129\" beast, all without requiring any case machining. At its core is the advanced S\u0026amp;S oil pump and cam plate, featuring independent scavenge sections for both the flywheel cavity and cam chest, ensuring optimal oil evacuation and reduced oil carry-over. Enhanced with debris screens in both scavenge pickups and a strategically placed magnet in the cam chest, this system actively prevents harmful contaminants from reaching the oil pump. Riders will appreciate the increased oil flow capacity on both the feed and scavenge sides, complemented by an adjustable pressure relief valve that can be fine-tuned even while installed in the engine.\u003c\/p\u003e\n\u003cp\u003eBeyond superior oil management, this S\u0026amp;S Cycle performance kit includes Quickee pushrods with accompanying pushrod tubes, S\u0026amp;S premium tappets, and robust S\u0026amp;S hard anodized, black coated billet aluminum tappet cuffs for exceptional durability. High-performance conical single wire valve springs are included, capable of accommodating cams with up to 0.605\" lift, ensuring compatibility with the included 496 camshaft. A multi-layered steel (MLS) head gasket provides a reliable seal for the increased compression. Designed and made in the USA, this kit retains your stock engine height, works seamlessly with stock crankcases and both stock or S\u0026amp;S roller rocker arms, and ensures your original engine serial numbers are preserved, making it a truly integrated and powerful upgrade for your Harley-Davidson Milwaukee-Eight big bore project.\u003c\/p\u003e\n\u003ch2\u003eFeatures \u0026amp; Highlights\u003c\/h2\u003e\n\u003cul\u003e\n    \u003cli\u003e\n\u003cstrong\u003eEffortless Big Bore Upgrade:\u003c\/strong\u003e Transform your 107\" Milwaukee-Eight into a powerful 129\" engine with a direct bolt-on kit, specifically designed for M8 models including VVT, requiring no case machining and retaining your original engine serial numbers.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eOptimized Oil System:\u003c\/strong\u003e Features an S\u0026amp;S oil pump\/cam plate with independent scavenge sections for superior oil evacuation, debris screens, a cam chest magnet for contaminant prevention, and increased oil flow capacity for enhanced engine longevity.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eAdjustable Performance:\u003c\/strong\u003e The adjustable pressure relief valve allows for fine-tuning of oil pressure even after installation, providing precise control over your engine's lubrication system.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eDurable Valvetrain Components:\u003c\/strong\u003e Includes S\u0026amp;S Quickee pushrods, premium tappets, and hard anodized black billet aluminum tappet cuffs for robust and reliable valve operation under high-performance conditions.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eHigh-Performance Valve Springs \u0026amp; Camshaft:\u003c\/strong\u003e Equipped with high-performance conical single wire valve springs supporting up to 0.605\" lift and the aggressive S\u0026amp;S 496 camshaft for significant power gains.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePrecision Sealing:\u003c\/strong\u003e Comes with an MLS (multi-layered steel) head gasket, ensuring a durable and reliable seal for increased compression and performance.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003cul\u003e\n    \u003cli\u003eBrand: S\u0026amp;S Cycle\u003c\/li\u003e\n    \u003cli\u003eEngine Compatibility: Harley-Davidson Milwaukee-Eight (M8) models, including VVT\u003c\/li\u003e\n    \u003cli\u003eDisplacement Increase: 107\" M8 to 129\"\u003c\/li\u003e\n    \u003cli\u003eCamshaft Included: S\u0026amp;S 496 Camshaft\u003c\/li\u003e\n    \u003cli\u003eValve Spring Max Lift: 0.605\"\u003c\/li\u003e\n    \u003cli\u003eTappet Cuffs Material: Billet Aluminum, Hard Anodized, Black Coated\u003c\/li\u003e\n    \u003cli\u003eHead Gasket Type: MLS (Multi-Layered Steel)\u003c\/li\u003e\n    \u003cli\u003eCase Machining Required: No\u003c\/li\u003e\n    \u003cli\u003eRetains Stock Engine Height: Yes\u003c\/li\u003e\n    \u003cli\u003eWorks with Stock Crankcases: Yes\u003c\/li\u003e\n    \u003cli\u003eWorks with Stock\/S\u0026amp;S Roller Rocker Arms: Yes\u003c\/li\u003e\n    \u003cli\u003eOriginal Engine Serial Numbers Retained: Yes\u003c\/li\u003e\n    \u003cli\u003eMade in: USA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEAN:\u003c\/strong\u003e 09040231\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"S\u0026S Cycle","offers":[{"title":"Default Title","offer_id":63699719749962,"sku":"09040231","price":71341.0,"currency_code":"SEK","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0971\/0016\/9546\/files\/9e9ae4251ca84225079c14dbcdd2b691.webp?v=1790463210","url":"https:\/\/partsdenmark.se\/products\/s-s-cycle-power-pack-big-bore-bolt-on-kit-129-vvt-for-m8","provider":"Parts Denmark","version":"1.0","type":"link"}
