Guide (5.0mm Conv.), C630, Intake, Honda®, CB™ 350 Twin CL/K2 5.00mm Conv., 1968-1973

5.00mm Conversion System We choose to use the copper based C63000 nickel-aluminum bronze as a material to make our bronze valve guides because of its ideal characteristics for the application. The 5% nickel content provides superior resistance to wear, and the approximately 80 percent copper content delivers outstanding heat conductivity. KPMI® guide profiles are designed to have minimal effect on the airstream while maintaining critical cross sectional thickness in high temperature areas, which promotes high performance and endurance.
