Frequently Asked Questions

What does +0.001 oversize mean?

The guide is 0.001 inch larger in diameter than stock, designed for engines where the original guide bore has worn. Requires a correspondingly oversized valve stem.

Do I need to bore the head to install this?

No — this guide drops into the stock bore. If your bore is damaged, you may need a larger oversize or have the head reworked by a machine shop.

Is this for intake or exhaust?

Intake only. Order a separate exhaust guide part number if you need to replace exhaust valve guides.

Will this fit my 2004+ Sportster?

No — this part is for 1986-2003 Sportster and 1984-1999 Evolution engines. Newer models use different guide designs.
