Frequently Asked Questions

What does +0.003 in oversize mean?

The guide is machined 0.003 inches larger than OEM spec, requiring the cylinder head bore to be reamed to match before installation.

Will this fit both EVO and Sportster engines?

Yes — this part fits EVO engines 1984-1999 and Sportster engines 1986-2003 as an exhaust guide.

Is installation a DIY job?

No — valve guide installation requires precision cylinder head boring and press-fit equipment. Have a machine shop or engine builder handle this.

What's the difference between intake and exhaust guides?

Exhaust guides run hotter and experience more wear. This is the exhaust version — intake guides use a different part number.
