KIBBLEWHITE Valve Guide - Manufacturer Ref. 80-80120

Designed for the exhaust of Enduro engines, this Kibblewhite valve guide is machined from C63000 nickel-aluminium bronze, an alloy containing approximately 5% nickel and ~80% copper. This material provides good wear resistance and thermal conductivity suitable for high-temperature areas, while adhering to the standards of high-performance distribution parts. Made in the USA, it features optimised profiles to minimise the impact on gas flow while maintaining critical thickness where heat and wear are highest.

Ideal for engine preparations and revisions for trails and Enduro, this guide is aimed at riders concerned with durability and assembly precision when replacing valves. Compatible with many models, common uses include the YAMAHA WR 426 F (2002) and WR 400 F (1998-2002). Replace your worn guides to restore a clean seat, limit play, and maintain optimal sealing of the distribution.
