The all new S&S Super Sidewinder™ Plus (SSW+) V2 Big Twin style long blocks offer the ultimate in performance and the latest technology for owners of 1984-'99 Evolution Big Twin motorcycles. With 41/8" bore these are the largest street engines S&S has ever offered, but that’s not the end of the story. The new 41/8" bore cylinders and SSW+ cylinder heads have bigger fins for improved cooling. By coupling the new cylinders with 41/8", 43/8", and 45/8" strokes, we can offer displacements of 111", 117", and 124".

To make the best use of those cubic inches, all SSW+ engines are equipped with the S&S Super G carburettor and the new S&S 585 camshaft for the 111", the S&S 600 camshaft for the 117", and the new S&S 640 camshaft for the 124".

In addition to the improved cooling and larger displacement, the SSW+ engines have a number of exclusive features that enhance performance and improve engine life. Special crankcases are used to house the SSW+'s 41/8" bore cylinders and the pressed together flywheel assembly. A special newly designed oil pump provides higher oil volume, maintains higher oil pressure, and increases crankcase oil scavenging. Oiling jets provide a spray of cooling oil to the bottoms of the pistons whenever the oil pressure is over 10 psi, and with the new oil pump, that is anytime the engine speed is above idle.

The crankcases are machined to return top end oil directly to the cam chest instead of to the flywheel cavity. This prevents crankcase pressure from travelling up the cylinder head oil drain passages and pressurising the rocker boxes. In addition, a one way valve in the breather circuit prevents air from entering the crankcase through the breather. The resulting decrease in internal engine pressure reduces oil leaks and oil carryover.

Assembled long block super sidewinder plus v2 style 111" 117" 124" The SSW+ cylinders are machined from stress relieved aluminium castings with cast-in iron liners. Each cylinder has vertical fins in the front and rear that serve to increase cylinder rigidity. Better cylinder rigidity means better dimensional stability as well as reduced transmission of mechanical noise. These engines are only available complete. Fits all EVO frames (stock height)
