Common questions
When should I use a +0.002 oversize valve guide?
A +0.002 oversize guide is typically used when your stock guides are worn beyond the tolerance that a standard or +0.001 guide can address. A machine shop will measure your cylinder head bores and recommend this size if necessary.
Is this an intake or exhaust valve guide?
This specific part is an intake valve guide only. If your engine rebuild calls for both intake and exhaust guides, you will need to order the corresponding exhaust guide separately.

Yes, this KPMI +0.002 bronze intake valve guide is compatible with Harley Evolution Touring models from 1984-1999 and Sportster models from 1986-2003. We recommend confirming fitment with our Shop by Bike tool.
