Frequently Asked Questions

Will this pump work with my stock oil lines and fittings?

Verify fitment with S&S Cycle or your builder — some custom systems may require adapter fittings depending on engine configuration.

Can I adjust the relief valve after installation?

Yes — the adjustable pressure relief valve can be tuned with the engine still mounted in the frame.

Does this require internal engine modifications?

Installation involves cam plate removal and oil pump replacement. Consult an engine builder or shop manual for your specific model.

What's the benefit of independent scavenge sections?

Separate scavenge paths for the flywheel cavity and cam chest ensure both areas drain efficiently, reducing oil aeration and heat buildup.
