KIBBLEWHITE Valve Guide - Manufacturer's Ref. 20-2121
Machined bronze C630 nickel-plated intake valve guide, designed to restore precision in the timing on vintage motorcycles, roadsters, and touring bikes. This shoulder guide combines a high copper content (approximately 80%) and 5% nickel to provide good wear resistance while maintaining suitable thermal conductivity for cooling the valve seats. Made in the United States.
Ideal for engine builds, restoration, or regular maintenance, this guide will align the valve stems and limit axial play for more reliable valve timing. Particularly suitable for 2004 Harley-Davidson FXSTSI / FXSTI / FXSTDI 1450 (FS2) models listed among common applications.
KIBBLEWHITE original product, reference 20-2121 — a solid replacement component for those who want to preserve the soul and performance of a classic motorcycle without compromising on engine parts.
