What components are NOT included with this engine?

This long block engine does not include the fuel and ignition systems. You will need to reuse your existing carburetor, air cleaner, and aftermarket ignition.

Will I need to modify my existing exhaust or intake?

The cylinder heads are specially machined to allow the use of stock-length manifolds, so your existing intake should work. Re-jetting your carburetor will be required to properly tune it for the new engine.

What is the warranty on this S&S Cycle engine?

All S&S V-Series engines, including this V124 Long Block, come with a 2-year warranty from the manufacturer.

About this part

Product Details

S&S Cycle is well-known for building high-performance motorcycle engines and components that offer a significant step up from stock. This V124 Long Block Engine is a prime example, offering an economical path to upgrade your Evolution-powered motorcycle. It's designed to bolt in using your existing carburetor and aftermarket ignition, saving you time and money compared to a full rebuild.

This engine comes with specially machined cylinder heads that allow you to use your stock-length manifolds and your current carburetor, though re-jetting will be necessary. By not including the fuel and ignition systems, S&S Cycle lets you reuse your existing setup, further reducing costs. Inside, you'll find premium S&S components, including their own cylinder heads, valve springs, and forged rocker arms. The crank and case are also machined to accept a crank position sensor, making it EFI compatible if you decide to go that route down the line. This makes the replacement process faster than rebuilding your original engine.

This engine includes a 2-year warranty and is proudly made in the USA. Please note that this engine is not CARB approved and cannot be shipped to California.
