Frequently Asked Questions

What does the +0.003 in oversize mean?

The guide bore is 0.003 in larger than stock, allowing installation of oversized valve stems to restore clearances when original guides wear.

Is this for intake or exhaust?

This is an intake valve guide. Exhaust guides require a different part number.

Do I need special tools to install this?

Valve guide installation requires a press or removal/installation tool. Have a shop handle it if you lack the equipment.

Will this fit my 2004+ Sportster?

No — this guide is for 1986–2003 Sportster and 1984–1999 EVO engines. Newer models use different guide sizes.
