The Kibblewhite Kawasaki Cylinder Head Kit (Part 40-41520) offers a comprehensive solution for high-performance engine rebuilds. This kit includes a complete top end gasket set, featuring base, engine case, exhaust, head gaskets, along with essential O-rings and washers to ensure a secure seal. It also contains a full set of KPMI® standard valves, providing reliable performance for demanding applications. The kit is designed to enhance engine durability and efficiency, making it an ideal choice for enthusiasts seeking to improve their Kawasaki engine’s power and longevity.
The high-performance titanium spring kit included in this package ensures optimal valve operation under high RPM conditions, reducing valve float and maintaining proper valve timing. Complete valve guides are supplied, with C630 guides crafted from a copper, nickel, and aluminum blend for excellent heat dissipation and wear resistance, and C674 guides made from a softer Manganese alloy that can be easily reamed for precise fitment. The Viton® valve stem seals help prevent oil leakage, contributing to cleaner emissions and reduced oil consumption.
Black Diamond™ valves feature a one-piece forged stainless steel construction, impregnated with a German process to improve wear resistance and reduce friction, thereby extending valve life. In contrast, White Diamond® valves are CNC-machined from a single forging of EV8 stainless steel or Inconel-751, then hard chromed with a 360° anode finish to provide the highest grade of a hard chrome surface. These valves are engineered for durability and performance, suitable for high-stress engine environments. Overall, this kit provides all the essential components needed to rebuild or upgrade your Kawasaki engine for increased power, reliability, and efficiency.
