KIBBLEWHITE Valve Guide – Ref. 80-80420
Designed for quad engines requiring robustness and thermal stability, this Kibblewhite valve guide is machined from nickel-aluminium bronze C63000. The composition (approximately 80% copper and 5% nickel) provides excellent thermal conductivity and wear resistance suitable for valve seat areas subjected to high temperatures. The internal profiles are optimised to minimise the impact on gas flow while maintaining critical thickness in hot areas, thus promoting endurance and operational stability.
Ideal replacement part for quad riders seeking precise engine restoration: compatible with several Yamaha 700 models (notably YXM 700 VP Viking EPS, YFM 700 RSE Raptor SE, and YFM 700 R Raptor 2025). Product intended for maintenance and repair operations of the valve train by qualified mechanics.
