Power Pack - 4.375" Stroke - Water Cooled - Black w/Highlights - M8

Upgrade your M8 engine with the S&S Cycle Power Pack, designed for optimal performance and durability. This bolt-on kit features a 4.375-inch stroke with water cooling, ensuring efficient thermal management during high-performance riding conditions. Crafted from high-quality materials, it includes forged pistons that provide superior strength and longevity, making it an excellent choice for demanding applications. The kit requires no case machining, simplifying installation while maintaining precise alignment and fitment. It also includes an oil pump and cam plate with removable passage plugs for easy servicing, along with independent scavenge sections that improve oil flow and debris management. The debris screens in both scavenge pickups and a magnet in the camchest help prevent debris from reaching critical components, enhancing engine reliability. The design offers a 44% increase in supply side oil flow and a 58% increase on the scavenge side, promoting better lubrication and cooling during intense operation. An adjustable pressure relief valve allows fine-tuning of oil pressure once installed in the engine. The kit also includes Quickee pushrods for quick installation and precise valve train control. Hand-assembled tappets with tight tolerances reduce valve train noise from startup to shutdown and minimize leak-down rates, ensuring consistent engine performance. The hard anodized black-coated billet aluminum tappet cuffs provide high stability in high lift and high rpm situations, maintaining durability and performance. This comprehensive upgrade package is made in the USA, combining advanced engineering with reliable manufacturing, to deliver a significant boost in power and engine efficiency for your M8 motorcycle.
