Solid Carbide Reamers

•  KPMI® solid carbide reamers provide long life and repeatability
•  Solid carbide, 6-flute design, share the chip load and ease the sizing operation
•  Extra-long-pilots for stability and alignment 
•  Ideal for: Manganese Bronze or Cast Iron
•  The KPMI® reamer diameters offered, provide recommended and optimum valve-guide-clearances

KPMI® Carbide valve guide reamers are manufactured from Solid Carbide and then heat treated and ground. All KPMI® reamers are ground to: +/- .0002”.  KPMI® carbide reamers are straight-flute and have a 6-flute design. The pilot portion of KPMI® reamers are 1.0” to 1.5” long.  Insert the pilot into a guide that you intend to size.  Using a hand held drill, apply honing oil or ATF before and during reaming a guide.  KPMI® reamers have been specifically designed for Manganese Bronze valve guides and Cast Iron. Do not attempt to use these reamers to size C630 Nickel Aluminum Bronze guides.  Also, once a reamer is used on Cast Iron, it’s not advisable to then use it on a bronze guide.

Lightweight Racing Beehive Spring Kit and Components for Husqvarna® & KTM® Various 450's 2013-2018 

By taking advantage of the latest development in valve spring wire chemistry and manufacturing techniques, KPMI® has developed ovate wire Beehive style springs that will live and perform at a high level in Husqvarna® and KTM® applications. By coupling these developments with strict KPMI® design protocols and employing multiple design simulation and FEA analysis software, we were we able to overcome the torsional stresses unique to ovate wire springs that previously limited their operating parameters. KPMI® Beehive Springs are progressively wound using Kobe Super-Clean chrome silicon based wire that is heat treated and shot peened. KPMI® uses its tightly toleranced, FEA designed hardened Titanium retainers in these applications to ensure correct assembly height and resist keeper pull through. The hardened steel basewashers included in these kits are designed to locate the spring and control lateral movement.


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.


All KPMI® Black Diamond™ Stainless steel valves are impregnated by a special German process to a depth of .002", with a surface build up of .0002". This Black Diamond process improves wear properties, reduces friction, and provides resistance to corrosion and wear that is superior to chrome and nickel electrolysis plating. Each valve is designed using Finite Element Analysis software, and profiles are tested on our computerized flow bench. Black Diamond Valves are lightweight, strong, one piece forgings with profiles that provide excellent flow characteristics.

Lightweight Racing Spring Kits with New H.T. Steel Retainers for Yamaha® YXZ / Triples Various Applications


•  High-Performance Spring Kit
•  H.T. Tool Steel Retainers
•  Your Titanium Retainer Alternative

KPMI® performance valve spring kits are modeled using cam profile and simulation software. By utilizing Finite Element Analysis (FEA) software, it was possible to take advantage of the increased strength and wear resistance of a heat treated steel retainer, while reducing its mass to within grams of a comparable titanium retainer.

Kit Includes:
•  Springs, H.T. Steel Retainers, and H.T. Steel Basewashers

Beehive Spring Kits, 0.610" & 0.660" Lift for Various Harley-Davidson® Applications


By taking advantage of the latest development in valve spring wire chemistry and manufacturing techniques, KPMI® has developed ovate wire Beehive style springs that will live and perform at a high level in Harley Davidson® applications. By coupling these developments with strict KPMI® design protocols and employing multiple design, simulation, and FEA analysis software, we were we able to overcome the torsional stresses unique to ovate wire springs that previously severely limited their operating parameters. This was critical, as there are nearly 100 camshaft part numbers available for these applications. KPMI® Beehive Springs are progressively wound using Kobe Super-Clean chrome silicon based wire that is heat treated and shot peened. KPMI® uses its tightly toleranced, FEA designed hardened steel retainers in these applications to insure correct assembly height and resist keeper pull through. The hardened steel basewashers included in these kits are designed to locate the spring and control lateral movement.
