20-2322C KPMI, intake valve guide. Cast iron. +.002"

Restoring a classic Sportster requires precision, especially when it comes to the valvetrain. This Kibblewhite cast iron intake valve guide is built for 1957 to 1983 Sportster models, offering maximum durability for riders who put on serious miles. Cast iron remains the preferred material for touring applications due to its excellent wear characteristics. This guide is machined to a +.002 inch oversize on the outer diameter to ensure a secure fit in cylinder heads with slightly enlarged guide bores. The standard reference dimensions for this application are a 0.5650 inch outer diameter, 0.3085 inch inner diameter, and a 1.77 inch overall length. Sold individually, these guides are essential for a professional-grade top-end overhaul.
