Frequently Asked Questions

Will this fit my 2004+ Sportster?

No — this guide is for 1986–2003 Sportster and EVO-engine big twins. 2004+ Sportsters use different heads.

Do I need to bore my head to install this guide?

No — the +0.004 oversized diameter allows direct replacement into existing valve guide bores without head modification.

What's the difference between this and the +0.008 version?

This +0.004 oversized guide is the first step for worn guides. The +0.008 is available if guides are more severely worn.

Is this for intake or exhaust valves?

This is an exhaust valve guide. Intake guides are a separate part number.
