S&S Cycle has built American V-twin performance parts in Viola, Wisconsin since 1958 — flywheels, carburetors, cams, cylinder heads and complete crate engines. When a Harley owner talks about a 124, a 128 or a 131 build, they are usually talking about S&S. Few names carry more weight with engine builders in this space.

Designed for a straightforward upgrade, this kit allows you to boost displacement without the need for extensive machine work, cylinder head modification, or flywheel rebalancing.

After much fabrication and alternative parts, it is installed. Not having a manifold ported for a map sensor complicates things significantly. I wasn’t going to settle for some pro rated refund because it was out of box. Much work left to do, but I’m committed to making it work.
