Frequently Asked Questions

Will this fit my 1999 Dyna with fuel injection?

No — this stator is not designed for EFI applications. EFI models require a different stator.

What voltage does this regulator output?

14.25V at idle, designed for maximum charging output and to support aftermarket electrical upgrades.

Does the vented rotor make a difference in performance?

Yes — the vented design improves heat dissipation, allowing the stator to run cooler and maintain peak output longer under load.

Will this work with my OEM primary housing?

Yes — the narrow profile of both rotor and stator is designed to fit existing OEM primary housings on compatible models.
