Frequently Asked Questions

Will this work on my EFI Harley?

No — this stator is not designed for EFI applications. Check Compufire's EFI-specific part numbers if your bike has fuel injection.

Does the vented rotor really keep the stator cooler?

Yes. The vented design improves airflow through the rotor, reducing heat buildup and allowing the stator to maintain higher output in sustained riding.

Can I use this with an aftermarket primary cover?

The narrow rotor and stator profile are designed for OEM primary covers. Verify fitment with your aftermarket cover manufacturer before installation.

What voltage does it put out at idle?

14.25V — higher than stock, which charges batteries faster and powers aftermarket electrical loads more reliably.

Is this made in the USA?

Yes. Compufire manufactures this stator in the USA.
