Review YAMAHA Flange Mount Carburetor Oem Mikuni 175 fits CT3 1973

The Yamaha 314E carburetor, manufactured in 1973 for the CT3 flange mount application, is a classic and highly sought-after component for vintage motorcycles. This carburetor, produced by Mikuni, is a single-venturi, constant-depression type, which ensures optimal fuel-air mixture for internal combustion engines.

The 314E is characterized by its smooth, round edges and polished finish, adding to its aesthetic appeal. Its dimensions are approximately 175mm in length, 112mm in width, and 102mm in height, making it a suitable fit for the specified CT3 flange mount.

This Mikuni carburetor features a needle and seat jet system for fine-tuning the fuel delivery. The needle jet is adjustable via a screw located on the top of the carburetor, providing the rider with the ability to calibrate the fuel mixture according to specific engine conditions. The seat jet, located beneath the needle jet, regulates the idle mixture.

The 314E utilizes a float bowl with a capacity of approximately 55cc (0.055 liters). The float bowl is designed to maintain a consistent fuel level, ensuring a steady supply of fuel to the engine. The float bowl gasket and needle jet o-ring are included in the package, ensuring a proper seal for optimal performance.

The carburetor is equipped with a choke mechanism, which can be engaged by pulling a cable connected to the left handlebar grip. This feature allows for easy starting, especially in cold weather conditions. The choke mechanism is designed to gradually decrease the fuel mixture enrichment as the engine warms up, preventing flooding and ensuring a smooth transition to normal operating conditions.

The venturi diameter of the 314E is approximately 24mm, providing an adequate fuel delivery for the average-sized, air-cooled motorcycle engine. The carburetor is also equipped with an idle mixture adjustment screw, allowing the rider to fine-tune the idle mixture for optimal engine performance.

The 314E is constructed from high-quality materials, ensuring durability and longevity. The body is made from lightweight aluminum, while the needle and seat jets are made from stainless steel, resistant to corrosion and wear. The carburetor also features a brass fuel bowl, which is less prone to corrosion compared to other materials.

In summary, the Mikuni 314E 1973 CT3 flange mount carburetor is a high-performance, durable component for vintage motorcycles. Its smooth design, adjustable fuel mixture, and reliable operation make it an essential addition to any classic bike restoration project.
