The advantages and disadvantages of carbureted motorcycles, when compared to their injection counterparts, constitute a lively debate since the introduction of the fuel injection system. Today, even though the majority of high-performance bikes feature injection systems, many motorcycles are still equipped with carburetors. While fuel injection systems can ensure unmatched efficiency and easier cold starts, carburetors are easier to maintain in top shape. Even though a carburetor itself is almost indestructible, it has some fine parts that need special care to maintain the throttle responsiveness and original efficiency. Among these parts, jets and needles are by far the most crucial.
The main jet controls the gasoline flow during acceleration; the pilot jet adjusts the amount of fuel at idle; the jet needle regulates the gas when opening and closing the throttle between 20 and 80% power. The needle valve ensures that the fuel inside the carburetor chamber is maintained at the same level. Beyond the regular maintenance, the replacement of stock jets and needles with their aftermarket analogs is a proven method of customization for improving performance or reducing fuel consumption. In our online store, you can find a large assortment of premium Harley Davidson motorcycle carburetor jets and needles carefully designed by some of the top-ranked brands.
