Partz: Breathing on the beast

Harley shook up the heavyweight motorcycle world last fall with the introduction of their first completely new engine since the release of the Twin Cam in 1988, the Milwaukee-Eight. In an effort to supply M-8 owners with even greater performance without sacrificing warranty coverage, reliability or ride-ability, The Motor Company has just released the new street-legal Screamin’ Eagle Milwaukee-Eight Stage IV Kit for both the 107 and 114 c.i. models. Claiming to boost horsepower to a whopping 52 percent over stock while gaining “stump-pulling torque,” some of the kit’s components include CNC ported heads with performance
springs, a massive 64mm throttle body (stock is 55mm), high-flow injectors, 4.075-inch cylinders, high-compression aluminum-coated pistons, a SE8-515 cam and high-performance tappets. To handle the additional power, the kit also comes with Screamin’ Eagle High Capacity Clutch Springs and Plates. The kit will increase M-8 107 engines to 114 cubic inches and take the M-8 114 up to 117. Available for all 2017-later H-D models equipped with either air/oil cooled or Twin-Cooled Milwaukee-Eight engines, all kits carry the same price tag of $2,595.95 excluding taxes, shipping and labor costs for installation.
