Not the most sexy products, but because of the number of old Flathead motors (Flatties) being put back on the road and needing to breath a new life, it is good to know that Kibblewhite Precision Machining Inc., since 75 years the worldwide leader in high performance valvetrain components, now offers forged Black Diamond® valves and guides for Harley-Davidson® Flathead motors model years 1930 to 1973.
Once only available by special order, Kibblewhite now stocks the most popular valves and guides for the Harley-Davidson® Flathead motor. “We have seen such a dramatic increase in orders for our Flathead motor performance products that the choice to go into larger scale production was natural.” Say’s Butch Larroche, Sales Manager for Kibblewhite Precision Machining Inc. It is a great feeling to be able to say, yes we have that in stock, when we get a call about a Flathead motor needing help”
These high tolerance, machined valves are the ideal choice for Flathead motors with limited top end oil circulation. The KPMI Flathead guides are manufactured with a proprietary cast iron blend and machined perfectly to match the performance needs of these motor types. Their ultra hard and dramatically smooth finish is engineered for optimal performance in these higher temperature running motors. KPMI’s high tolerance, cast iron guides are designed to match the Black Diamond® valves and motor perfectly for maximum horsepower gains. Superior bore finish and industry leading wear characteristics are gained via extreme density, fine grain and the granular structure of each race proven KPMI valve guide.
