The 131-inch stroker kit from S&S boosted my bike’s power and performance impressively while matching the factory look seamlessly, though reaching the full 131 cubic inches required buying their stroker flywheel too.

This 131 inch stroker kit adds a ton of power but I’m skeptical about the longevity and reliability compared to OEM parts.
