Upgrade your twin cylinder engine with the NAMURA NA-50090-BK Top End Kit, designed for optimal performance and durability. This comprehensive kit includes a piston, rings, wrist pin, clips, top end bearing, and gasket kit, providing all the essential components for a complete top end rebuild. Crafted with precision, the kit ensures a seamless fit and reliable operation, making it ideal for enthusiasts seeking to enhance engine efficiency and longevity.
Features include MOS2 (Teflon/Molybdenum) coated piston skirts, which are applied through a rolled-on process that creates a bond ten times stronger than traditional spray-on coatings. This coating improves heat transfer, reduces friction, and helps prevent cold seizures, contributing to smoother engine operation. The machined smooth heads reflect combustion heat more effectively and reduce carbon buildup, which can lead to increased horsepower and up to 6% better fuel economy.
The pistons feature anodized domes for increased heat resistance and durability, with anodized components being 75% stronger than non-anodized alternatives. This enhancement ensures the piston withstands higher temperatures and stress during operation. Additionally, the hypereutectic casting process used in manufacturing provides higher silicon content for reduced expansion rates and greater wear resistance, enabling the piston to endure higher cylinder temperatures without compromising performance. Overall, this top end kit offers a robust solution for rebuilding or upgrading twin cylinder engines, combining advanced materials and coatings for improved power, efficiency, and engine life.
