Kibblewhite Precision Machining supplies valves, valve springs, guides and complete top-end kits used by professional V-twin engine builders. Its black diamond valves and spring kits are a standard specification on high-lift cam builds.
When rebuilding a Shovelhead top end, proper valve stem clearance is critical for performance and longevity. This KPMI exhaust valve guide is designed to restore that precision. Crafted from bronze and sized at +0.002 oversize, it's ready for a fresh ream to bring your cylinder heads back into spec.
Worn valve guides can lead to oil consumption, reduced performance, and premature valve train wear. This KPMI bronze exhaust valve guide is a direct replacement for 1978-1983 Shovelhead engines, engineered to provide a solid foundation for your valve job. The +0.002 oversize ensures you have enough material to achieve optimal valve stem clearance, critical for a tight, high-performing engine.
Installing new valve guides is a key step in any comprehensive Shovelhead cylinder head rebuild. This KPMI guide is intended for use when your original guide bores have worn beyond standard size, providing the necessary material for a precise fit. Professional installation and machining are recommended to ensure correct alignment and final sizing for your valve stems.
What does +0.002 oversize mean for this valve guide?
This means the outer diameter of the valve guide is 0.002 inches larger than stock. It's designed to be pressed into a cylinder head with a slightly worn bore, and then reamed or honed to the correct inner diameter for your valve stem.
Is this valve guide for the intake or exhaust side?
This specific part is an exhaust (EX) valve guide. If you need an intake guide, you will need to order that separately as it is a different part.
Will this fit all Shovelhead models?
This KPMI valve guide is designed for Harley-Davidson Shovelhead engines from 1978 through 1983. Please confirm your motorcycle's year and model using our Shop by Bike tool to ensure perfect compatibility.

This set of three cables looks to be great quality. I have not installed these yet but are ready for when I replace the starter which is still going strong after 32 years ! So to be ready, I have a new All-Balls starter and cable set ready to install when needed.
High quality. Good value for the money. My only complaint is that the ground cable was not included as thought it would be.
