One way to spend your Coronavirus quarantine time with your loved one is by adding a new Harley-Davidson Screamin’ Eagle Stage IV Kit to it. The MoCo just came out with two new Milwaukee-Eight big bore kits that take your V-twin up to 128 or 131 cubic inches.
The first Harley-Davidson Screamin’ Eagle Stage IV Kit takes a 107-inch powerplant to 128 ci. Features new CNC-ported heads with 1mm bigger valves than the previous generation, and fully machined combustion chambers. Coupled with the kit’s high-lift SE8-517 cam, high compression pistons and a 64mm throttle body and intake manifold, this combination delivers a thrilling 126 ft-lb of torque and 121 HP rear-wheel output when paired with Screamin’ Eagle Street Cannon Mufflers. It’s designed to run at high-end RPMs and provide a significant boost of torque from cruising speed.
With the largest displacement of any Harley-Davidson Stage Kit, this 114/117 ci to 131 ci Stage IV Kit was designed to deliver maximum horsepower. Packaged with patent-protected cylinder technology, it allows for the largest Harley-Davidson bolt-on engine upgrade to any Milwaukee-Eight motor. Features new CNC-ported heads with 1mm bigger valves than the previous generation, and fully machined combustion chambers. Coupled with the kit’s high-lift SE8-517 cam, high compression pistons, and a 64mm throttle body and intake manifold, this combination delivers a claimed 131 ft-lb of torque and 121 HP rear-wheel output when paired with Screamin’ Eagle Street Cannon Mufflers. Like the 128 conversion above, it’s designed to run at high-end RPMs and provide a significant boost of torque from cruising speed. Find out more at your local dealer or at the H-D website.
