Common questions
What does 0.010-inch oversize mean?
This valve guide is slightly larger in diameter than a standard guide. It's used when the valve guide bore in the cylinder head has been enlarged due to wear or a previous repair, requiring an oversized replacement.
Is this valve guide compatible with Twin Cam engines?
No, this KPMI valve guide is engineered specifically for Harley-Davidson Milwaukee-Eight (M8) engines only. Twin Cam engines require a different guide design.
Do I need to replace all valve guides when using an oversize guide?
It depends on the condition of your cylinder heads. If only one bore is worn or damaged, you might only need an oversize guide for that specific location. However, it's often recommended to inspect all guides and replace as needed for consistent performance. Always consult your service manual or a professional.
