Frequently Asked Questions

What does +0.003 oversize mean?

The guide is 0.003 inch larger in diameter than stock, sized to fit and seal in a worn or damaged guide bore that has expanded slightly.

Does this fit both intake and exhaust ports?

Yes — this guide works for either intake or exhaust positions on EVO engines.

Will this fit my 2000+ Harley?

No — this part is for 1984-1999 EVO big twin models only. 2000-up models with Twin Cam engines require different guides.

Do I need to machine my cylinder head?

If your guide bore is worn, your machine shop may need to ream it to the proper oversize dimension before installing this guide.
