KIBBLEWHITE Valve Guide - Manufacturer's Ref: 80-80050
Designed for guiding exhaust valves, this Kibblewhite valve guide is made in the United States from nickel-aluminium bronze C63000. Its composition (approximately 5% nickel and ~80% copper) provides a good balance between wear resistance and thermal conductivity, useful in cylinder head areas subjected to high temperatures. The internal profiles are optimised to minimise the impact on gas flow while maintaining the necessary thickness in critical areas, ensuring precise and durable valve guidance.
Ideal for off-road and enduro use where valve train reliability is crucial. This guide is particularly suitable for the Yamaha XTZ/XT 660 Tenere models listed below, but can also be used on other compatible applications depending on diameter and tolerances.
A simple yet essential replacement component to maintain a clean distribution and controlled wear on your trail or quad outings.
