MIKUNI MKJ45 Injector (manufacturer reference TM36/43-03) — replacement part designed for MKJ45 type carburetors. Engineered to ensure the delivery and atomization of fuel, this injector plays a central role in the air/fuel mixture ratio, idle behavior, and throttle response.
A frequently worn part on carburetors, a well-functioning injector contributes to a steady fuel supply and uniform fuel atomization. Replacing a worn or clogged injector is part of regular maintenance operations to restore precision to adjustments and prevent hesitations or misfires related to poor atomization.
Before installation, check the compatibility with your carburetor body and the condition of other components (jets, float, passages). Replacement and adjustments require a minimum of method: cleaning, checking clearances, and testing in cold/hot conditions to achieve optimal operation. Ideal for riders who maintain their carburetor assembly and want to preserve the responsiveness and consistency of their machine.
