Elevate your engine’s performance with the cutting-edge NA-40002-2K Top End Kit. Designed specifically for Yamaha engines, this comprehensive kit is packed with features that deliver exceptional performance, durability, and efficiency.

Key Features:

• Complete Top End Kit: Includes piston, rings, wrist pin, clips, top end bearing, and a MOS2 (Teflon/Molybdenum) coated gasket kit for comprehensive engine rejuvenation.
• MOS2 Coated Skirts: Our unique rolled on application results in a bond that is 10 times stronger than typical spray coatings, enhancing heat transfer, reducing friction, and minimizing the risk of cold seizures.
• Machined Smooth Heads: These heads reflect combustion heat effectively, reducing carbon buildup and protecting the piston top, which can lead to an increase in horsepower and fuel economy by up to 6% in some tests.
• Anodized Domes: Built to last, anodized domes increase both heat resistance and durability, making the pistons 75% stronger than those without anodization.
• Hypereutectic Casting Process: This advanced manufacturing technique ensures higher silicon content, resulting in reduced expansion rates and enhanced wear resistance, allowing the pistons to withstand elevated cylinder temperatures.
