This bolt-in kit increases engine displacement to 132 inches without requiring case machining, making it an ideal upgrade for riders seeking increased power and efficiency. The kit features a 4.32-inch bore with forged pistons that deliver an 11.0:1 compression ratio, ensuring durability and high performance under demanding conditions. The updated profile and precision engineering of this kit optimize airflow and combustion, resulting in improved throttle response and overall engine output. The inclusion of a high-quality oil pump and cam plate with a sleek blue anodized finish ensures reliable lubrication and longevity. Passage plugs are removable for easy servicing, and independent scavenge sections for the flywheel cavity and cam chest facilitate efficient oil circulation. Both scavenge pickups include debris screens, and a magnet in the cam chest helps prevent debris from entering the oil pump, protecting vital engine components. The kit also increases oil flow capacity on both feed and scavenging sides, supporting high-performance operation. An adjustable pressure relief valve allows fine-tuning of oil pressure without removing the unit from the engine. Quickee pushrods and premium S\u0026amp;S tappets improve valve train reliability, while hard-anodized, black-coated tappet cuffs made from billet aluminum provide added durability. S\u0026amp;S 550 cams are specifically designed for big bore applications, with valve springs capable of handling cams up to 0.605 inches lift. The high-performance conical single wire spring design enhances valve stability at high RPMs. Made in the USA, this kit is compatible with VVT models but not suitable for trike configurations. Please note that intake and rocker cover gaskets are not included. The Power Pack 550G is an excellent choice for riders looking to significantly boost their M8 engine’s power with reliable, high-quality components that deliver consistent performance.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eBig bore increase to 132 inches with no case machining required\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eUpdated profile with 4.32-inch bore cylinders and forged pistons\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eHigh compression ratio of 11.0:1 for increased power\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eIncludes S\u0026amp;S oil pump and cam plate with blue anodized finish\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eRemovable passage plugs for ease of servicing\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eIndependent scavenge sections for flywheel cavity and cam chest\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eDebris screens in both scavenge pickups to prevent contamination\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eMagnet in cam chest to help prevent debris from entering the oil pump\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eEnhanced oil flow capacity on feed and scavenge sides\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eAdjustable pressure relief valve for fine-tuning oil pressure\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eQuickee pushrods and premium S\u0026amp;S tappets for reliable valve train operation\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eBlack coated, billet aluminum tappet cuffs for durability\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eDesigned for big bore applications with S\u0026amp;S 550 cams\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eHigh-performance conical single wire valve springs up to 0.605\" lift\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eMade in the USA with quality and precision\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eCompatible with VVT models; not suitable for trike models\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eNote: Intake and rocker cover gaskets are not included\u003c\/li\u003e\u003c\/ul\u003e","brand":"S\u0026S CYCLE","offers":[{"title":"Default Title","offer_id":50412843270337,"sku":"0904-0217","price":3497.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0060\/5929\/4802\/files\/5839470.png?v=1784220316","url":"https:\/\/teamdreamrides.com\/products\/s-s-cycle-power-pack-550g-water-cooled-big-bore-kit-for-m8-engines-114-and-117-inch-with-chrome-pushrod-tubes","provider":"Team Dream Rides","version":"1.0","type":"link"}
