S&S Cycle 136" Big Bore Kits for M-8 Models

In the continuous pursuit of horsepower, bigger is always better, and that’s where S&S Cycle, the masters of 'Proven Performance', comes in with its biggest big bore kit yet.

Take the stock cases or S&S' recently released MK-Series crankcase and match them to these massive 4.320" bore cylinders and pistons - available in Black Granite, highlighted fins or wrinkle black finishes. 

"When paired with the 4 5/8" stroker flywheel, this combination results in a heart-pounding 136" monster of an M-8 engine that still perfectly fits in the stock chassis. 

The big bore stroker cylinder and piston kits for 2017-up M-8 models are available for 136" and 131" applications, with original engine serial numbers retained and .045" MLS (multi-layered steel) head gaskets.

They retain the stock engine height, include a 1312 or 136" cam cover badge and require S&S 4 5/8" stroker crank (part # 320-0605).
