Frequently Asked Questions

What does +0.004 oversize mean?

The guide bore is 0.004 inches larger than stock to accommodate a slightly oversized valve stem and restore proper clearance on worn engine blocks.

Is this for the intake or exhaust valve?

This is an exhaust valve guide. Order the intake part number separately if both guides need replacement.

Will this fit my 2004+ Sportster with Twin Cam engine?

No — this guide is for EVO and older Sportster engines only. Twin Cam and Milwaukee-Eight Sportsters require different guide part numbers.

Do I need special tools to install this?

Valve guide removal and installation typically requires a press or guide driver tool. Professional machine shop installation is recommended.
