Description
The KPMI Top End Service Kit with Stainless Steel Valve Conversion (Part Number 60-61850) is an essential upgrade for enthusiasts seeking to maximize the performance and durability of their Suzuki DR-Z400 motorcycles from 2000 to 2009. This comprehensive kit is specifically engineered to meet the demanding needs of racing MX bikes and quads, offering a combination of high-quality components designed to enhance engine efficiency and longevity.
The kit features a fully CNC-machined 2618 alloy piston with a performance skirt coating, designed with a domed piston deck that maintains high compression ratios. This innovative piston profile offsets any volume changes caused by valve dishes, ensuring optimal compression for better power output. The inclusion of a top-end gasket kit from Cometic guarantees a proper seal during assembly, providing a reliable foundation for your engine rebuild.
One of the standout features of this kit is the Black Diamond* stainless steel valve conversion system. These valves are engineered to double the service life compared to stock titanium valves, all while maintaining peak performance. The conversion kit includes dual spring titanium retainers capable of handling valve lifts of up to 0.440 inches, allowing for high-performance camshaft operation. Additionally, lightweight stainless steel valves contribute to reduced moving mass in the valvetrain, which can result in increased RPM and improved throttle response.
To complement these components, the kit provides all necessary rings, clips, pins, and seals required for a complete top-end rebuild. The included high-performance spring kit is compatible with high-performance cams, further enhancing engine responsiveness. With the combination of durable components and precision engineering, this kit ensures that your engine will perform reliably under racing conditions while enjoying extended service life. Whether you’re rebuilding your engine for the track or upgrading for increased power, the KPMI Top End Service Kit with Stainless Steel Valve Conversion offers an excellent solution for Suzuki DR-Z400 owners.
