Idle speed is as stable as a rock, and even in extreme working conditions, it is reliable: this STM idle air stepper motor is equipped with high-precision stepper control technology, which can adjust the intake air volume in real time, so that your Kawasaki's speed remains unchanged during idle - even if it stops abruptly after a sudden surge on the lake or starts at low temperatures, it can avoid the jerky feeling of the speed fluctuating. For players who love to play tail waves and water stunts on motorboats, stable idle means easier control when docking at the dock and towing up and down, with a sense of safety that can be fully loaded
