Description

50cc 4-stroke auto-clutch Honda-clone gas ATV and dirt bike engine with electric start and no reverse. The chain cover, carburetor joint (intake manifold extension), gaskets, O-ring, and carburetor mounting hardware is included

This Honda-clone engine is used in a wide variety of applications, including all-terrain vehicles (ATVs), dirt bikes, pit bikes, go karts, and dune buggies. Fairly universal in nature, this engine will replace many Chinese made OEM factory 50cc ATV & dirt engines, from manufacturers such as Baja Motorsports, Coolster, Motovox, Roketa, and Tao Tao.

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.
