& S Announces 131 ci Kits for 2017-up M8
This S & S Cycle 131 kit for 2017 and up M8 models " is the perfect sleeper package." Dealers and their customers can boost engine performance with a bolt in kit to " pump up the cubic inches " with a Bore and Stroke of 4.250 " x 4.625 " and bring compression to 11.0:1 without any machine work for installation. The cylinder finish matches the stock colors, so unless you install the included 131 " badge, no one can tell. All necessary gaskets are included, and the kit retains stock engine height. With the S & S HPT590 cam the stock 114 " horsepower has been seen to go up from 81.07 hp to as much as 146.62 hp with torque from 111.71 to 145.45 ft. lbs with the 131 " stroker kit, CNC heads, Big Bore Throttle Body, High-flow Stealth Air Cleaner kit and a 2-into-1 exhaust system. The kit works with the stock crankcases and original engine serial numbers are retained. The powder coat finish matches the factory finishes- there are three options, for choice of Wrinkle Black with or without highlight and Black Granite with highlight.
