Kibblewhite C674 Valve Guide (Manufacturer Part No. 80-80930) — Special Cross

Designed for reconditioning cylinder heads and replacing exhaust guides, this Kibblewhite bronze C674 guide offers a reliable solution for workshop tasks. Its manganese bronze material is softer, making it easier to bore and seat with a reamer or ball hone, especially in combination with an electric or battery-powered drill.

• Application: Exhaust

The C674 guides meet the same strict KPMI® tolerances as the range, while exhibiting lower strength and durability compared to the premium C630 nickel-aluminium bronze guides. Ideal for routine maintenance operations on off-road motorcycles, this guide facilitates the seating and adjustment of the valve seat without the need for expensive specialized tooling.
