Description
The 1P47FMD 50cc 4-stroke automatic Honda-clone gas ATV and dirt bike engine may be used in a wide variety of applications, including all-terrain vehicles (ATVs), dirt bikes, pit bikes, go karts, and dune buggies.
The 50cc ATV & dirt bike engine comes equipped with a #420 chain sprocket and electric starter motor. The chain cover, carburetor joint (intake manifold extension), gaskets, O-ring, and carburetor mounting hardware is included. The starter motor is our part number G07-1492 and can be found at the link below:

PLEASE NOTE:
The engine exhaust port has a machined cut-out side to receive a collared exhaust pipe. This is by design and not a product defect. The collared pipe fits down into the exhaust port with the diamond-shaped rhombus flange fitting over the studs.
An elbow-shaped carburetor joint (or intake manifold extension) is included with this engine. Depending on your vehicle type, this cast & machined "pipe" holds the carburetor at the proper angle and away from the engine head. Although the exhaust port with the two pre-installed mounting studs uses the same hole-spacing as the intake, this intake manifold extension does not work for the exhaust due to the cut-out on the exhaust port.
In addition, there are many different versions of 50cc 4-stroke engines used in the Chinese scooter, all-terrain vehicle, dirt bike, and go-kart market. Please be sure to check the detailed specifications and dimensions on our specifications list prior to ordering.
