Frequently Asked Questions

Will this fit my 2004+ Sportster?

No — this guide is specific to 1986-2003 Sportster. 2004 and newer Sportsters use different cylinder head geometry.

What does +0.004 mean?

The guide is machined 0.004 inches larger than stock to accommodate a slightly oversized valve stem, restoring proper clearance in a worn bore.

Is this an intake or exhaust guide?

Intake only. Exhaust guides require a separate KPMI part number.

Do I need special tools to install this?

Valve guide installation typically requires a proper press or pilot tool to avoid damaging the new guide during fitment into the cylinder head.
