Product Details  
Cylinder Kit - Monster Big Bore - 109" - Black w/Highlighted Fins - Evolution Big Twin '84-'99

Upgrade your Harley Evolution Big Twin engine with the REVOLUTION PERFORMANCE LLC Monster Big Bore Cylinder Kit, designed for 1984 to 1999 models. Crafted from aerospace-grade all-aluminum with advanced nickel-silicon-carbide (NSC) electroplated bores, these cylinders feature no sleeving, allowing for larger bore sizes that increase horsepower and performance. The NSC plating reduces friction, leading to lower engine temperatures and extending the lifespan of your engine components. This kit includes a pair of all-aluminum NSC-coated bore cylinders, custom forged pistons with high-tension rings specifically designed for NSC cylinders, wrist pins, circlips, and a head/base gasket set, providing a comprehensive upgrade package. Made in the USA, these cylinders require case boring, a process not recommended on OEM cases from 1995 and earlier, and may necessitate a 4-5/8
