Crazy Horse Motorcycles LLC, based in Kent, Washington, is the manufacturer of the “V-Plus” V-Twin motorcycle engine. They are an OEM supplier of this engine to individuals and custom bike builders. Each engine is proudly made in America with American components.
They are basically built around the Evo platform and will fit any Evo model. The only quirky aspect is the carburetor facing out the left side of the engine. Although, it creates no obstruction for the rider of any bike with fatbob tanks; otherwise it is a minor consideration. Any Evo exhaust system will fit the Crazy Horse format.
“Our goal is to provide a distinctive, powerful, and reliable V-Twin American made engine. By using superior grade components and craftsmanship, along with a generous warranty, we intend to be considered among the best engine manufacturers in the industry,” said John White, Da Boss.
White secured the rights to build these unique engines, enhanced the oiling system, the cylinder cooling capabilities, and they even purchased Ramsden foundry castings, which are semi-permanent steel tooling, so even the cases are no-longer sand-casted. In fact, this 100-inch V-Plus addresses some of the problems when pushing the size of standard Evo engines, with heavier cases and barrel material for stronger head bolt connections, so this 100-inch configuration based around 3 5/8-inch bore and 4 ¼ stroke is built to last with 9.5:1 compression from Keith Black hypereutectic pistons.
This engine affords builders the use of any conventional Evo ignition system, including Compu-Fire, Crane Hi-4, or Daytona Twin-tec systems, you name it.
Either a Mikuni 42mm or an S&S Super E carburetor can be installed. The latter requires removal of the rubber flange adapter and enlarging the two bolt holes.
