The Bad Dog 215 is a fuel-injected, sixty-degree air-and-oil-cooled 4-valve DOHC semi-unit V-Twin, displacing 3500 cc or 215 cubic inches. The bore-to-stroke ratio is over-square, with a six-inch bore and four-inch stroke. The con rods are several inches longer than the usual automotive type and run side-by-side on a single crank throw.

The crank is machined from billet steel and accurately counterweighted. The cases are billet aluminum, horizontally split, and are fitted with 426 hemi main and rod shell bearings. The drive side has two main bearings and the timing side uses a single main bearing with thrust washer.

An external multi-stage pump supplies and scavenges five liters of oil, which passes through a large oil cooler before returning to the oil tank. Oil jets set into the upper case cool the undersides of the pistons.

The timing side of the crank carries a shaft that mounts two cam chain sprockets, a Harley-style alternator rotor and a sprocket to drive the oil pump and timing disk. The crank-mounted cam chain sprockets turn intermediate sprockets which spin the cams.

The cylinders are machined from aluminum billet with pressed-in iron liners. The cylinder head will also be machined from an aluminum alloy with good strength at high temperatures. The head incorporates several design features to assist cooling.

The valve and port layout is designed to optimize gas flow and increase power, which will exceed three hundred horsepower.

Fuel supply is low-pressure electronic sequential port-type injection with two injectors per cylinder. Injection and spark timing are handled by a Motec M400 ECM. Scoops on each side of the fuel tank take in air, which is then filtered before it gets to a plenum between and above the cylinders.

The primary drive is a pair of herringbone gears for quiet operation with no side thrust. The clutch is a wet multi-plate design. The transmission has six speeds, using a rotary shift drum. The primary drive and transmission bolt both to the motor cases and to each other. The swingarm pivot is part of the transmission housing. The whole power unit mounts to the frame with a rubber vibration-insulating system that only allows movement in one plane.
