Frequently Asked Questions

What does +0.001 oversized mean?

The guide is 0.001 inches larger in diameter than stock, allowing it to fit into bores that have been honed for oversized guides due to previous wear.

Is this a direct replacement for the original valve guide?

Yes — it meets OEM specifications for EVO and Sportster engines and replaces the factory guide without modification.

Will this fit my 2004+ Sportster?

No — this part is for 1986-2003 Sportster models. 2004-up Sportsters use different engine architecture and require different guides.

Do I need a valve guide installer tool?

Yes — proper installation requires a valve guide removal tool and press to seat the guide correctly. A machine shop or experienced engine builder is recommended.
