Kibblewhite C674 Valve Guide — an intake guide designed for engine preparation and refurbishment in Enduro/Cross. Machined from C674 bronze (manganese alloy), this guide is softer and can be easily reamed: ideal for quickly reconditioning seats with an electric drill and then finishing with a Kibblewhite ball hone to achieve the appropriate valve clearance.

• Usage: intake
• Material: C674 bronze (manganese alloy), machining-ready finish
• Dimensions: Ø ext. 0.3563" (≈ 9.05 mm) — Ø int. 0.1570" (≈ 3.99 mm)
• Feature: softer guides, easy to ream and hone with portable tools
• Note: same strict KPMI® tolerances as other Kibblewhite references, but lower strength and durability compared to premium C630 nickel-aluminium bronze guides
• Origin: made in the USA

Designed for cylinder head preparation and maintenance operations on 2-stroke and 4-stroke off-road engines, this guide facilitates the machining and honing of valves without requiring heavy industrial tooling. Prefer it when looking for a simple and precise solution to restore intake seats.
