Kibblewhite C674 Valve Guide (Manufacturer Part No: 60-60290)
Designed for quad engines, this Kibblewhite bronze C674 valve guide is aimed at tuning and maintenance operations on intake seats. Made from softer manganese material, it facilitates boring and hand lapping or with Kibblewhite ball hones, and can be machined quickly even with an electric or cordless drill.
The C674 guides meet the same strict KPMI® tolerances as Kibblewhite references, while offering improved machinability; however, their strength and durability remain inferior to the premium C630 guides (nickel-aluminium bronze). Ideal for quick refurbishment operations and precise valve clearance adjustments on leisure engines.
Notable compatibility: SUZUKI LT-R 450 2X4 Quadracer (AL41A) - models 2007, 2008, and 2009. For tuners and home mechanics looking for an easy-to-machine, reliable intake guide that meets Kibblewhite standards.
