A two-stroke engine having both a direct injector and an indirect injector. The direct injector injects fuel into the cylinder without passing through the crank case. The indirect injector is in fluid communication with the crank case. It provides fuel delivery through the crank case and through a transfer channel to the cylinder. A controller is coupled to the direct injector and to the indirect injector. The controller starts, stops, and varies the fuel delivery of each injector. The controller is programmed to increase the fuel delivery of the indirect injector at a predetermined engine speed. The controller maintains primary fuel flow through the direct injector below a predetermined engine speed. The controller varies the fuel delivery based on at least one of following: engine speed, throttle position, exhaust valve position, intake air temperature, exhaust temperature, barometric pressure, coolant water temperature, and piston position.
