Kibblewhite C674 bronze valve guide, designed for engine refurbishment operations on quads and off-road machines. This softer guide facilitates boring and honing: ideal for workshops and DIY enthusiasts using ball hones and an electric or cordless drill to quickly finish the seat surface.
Note: C674 offers simplified implementation but has lower strength and durability compared to premium C630 guides (nickel-aluminium bronze) — suitable for quick machining and honing operations rather than applications requiring maximum longevity. Manufacturer reference 60-60060. Particularly suitable for SUZUKI LT-Z 400 models (2008–2018 versions) and a wide range of machines in the Trail/Adventure, Enduro, Quad, and Supermoto universes.
