This exhaust valve is engineered for superior flow, durability, and wear resistance, ensuring optimal engine operation and longevity. Made in the USA with meticulous attention to detail, this valve is a must-have for serious riders and engine builders.\u003c\/p\u003e\n\n\u003ch2\u003eDescription\u003c\/h2\u003e\n\u003cp\u003eThe Kibblewhite Black Diamond™ Valve is CNC machined from a one-piece forging of EV8 Stainless Steel, offering exceptional strength and lightweight properties. Its carefully engineered profile maximizes flow characteristics, contributing to improved engine performance. The valve undergoes a special German infusion process, penetrating to a depth of 0.002\" with a surface build-up of 0.0002\", enhancing wear properties, reducing friction, and providing unparalleled resistance to corrosion and wear—outperforming chrome and nickel electrolysis plating. Designed with Finite Element Analysis (F.E.A) software and tested on a computerized flow bench, this valve guarantees precision and reliability. The stem is coated with black nitroneg for added durability and reduced friction.\u003c\/p\u003e\n\n\u003ch2\u003eFeatures \u0026amp; highlights\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eCNC machined from one-piece forgings of EV8 Stainless Steel for exceptional strength and durability.\u003c\/li\u003e\n  \u003cli\u003eLightweight design improves engine response and reduces valve train stress.\u003c\/li\u003e\n  \u003cli\u003eSpecial German infusion process enhances wear resistance and reduces friction.\u003c\/li\u003e\n  \u003cli\u003eProvides superior corrosion resistance compared to chrome and nickel electrolysis plating.\u003c\/li\u003e\n  \u003cli\u003eDesigned using Finite Element Analysis (F.E.A) for optimized performance.\u003c\/li\u003e\n  \u003cli\u003eStem coated with black nitroneg for reduced friction and increased wear resistance.\u003c\/li\u003e\n  \u003cli\u003eProudly made in the USA, ensuring top-quality craftsmanship.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eTechnical specifications\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eBrand: KIBBLEWHITE\u003c\/li\u003e\n  \u003cli\u003eVendor Part Number: 40-40566\u003c\/li\u003e\n  \u003cli\u003eApplication: Exhaust\u003c\/li\u003e\n  \u003cli\u003eHead Diameter: 31.00 mm\u003c\/li\u003e\n  \u003cli\u003eLength: 3.230\"\u003c\/li\u003e\n  \u003cli\u003eMaterial: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003eProduct Name: Valve\u003c\/li\u003e\n  \u003cli\u003eStem Diameter: 5.50 mm\u003c\/li\u003e\n  \u003cli\u003eTulip Angle: 20°\u003c\/li\u003e\n  \u003cli\u003eUnits: Each\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eImportant to know\u003c\/h2\u003e\n\u003cp\u003ePlease ensure this valve is compatible with your specific engine model and intended use.
