Q & A

Ask a question
How can I get the panhead P93 engine to fit in a 2005 Softail frame Joseph asked on November 6, 2024

No, S&S does not make a complete engine for a 2000-2017 twin cam softail frame.

What style of transmission can i use with this motor? It's for a custom softail frame. JOSEPH ANGELO asked on August 15, 2024

The transmission fitment for a Big Twin Harley is dictated by the primary drive, not the engine. All softail 4, 5, and 6 speeds will work with this.

Can I use a Joe Hunt magneto with this engine? Can I use a Baker 6 into 4 kick start transmission with this engine? Jerry Roach asked on May 31, 2023

You shouldn't have any issues using the magneto but I would check with the magneto manufacturer to be 100% sure. These engines can be used with any 4, 5, or 6 speed transmission including the baker 6 into 4. The primary drive is what will change based on engine/transmission combinations.
