Frequently Asked Questions

Will this fit my 1990 EVO Big Twin?

Yes — this guide fits all EVO Big Twin models from 1984–1999.

What does +0.003 in oversize mean?

The bore is 0.003 inches larger than factory standard, allowing it to fit into a worn guide bore and restore clearance without requiring a complete head bore.

Do I need to hone the cylinder head bore before installation?

Yes — the cylinder head bore should be honed or reamed to match the +0.003 in oversize specification for a proper fit.

Is this for intake or exhaust?

This is an intake valve guide only. Exhaust guides are sold separately.
