TYPICAL 1Water supply hose of regulator valve 2Regulated water to injection fitting 3Water injected into the muffler
NOTE: The water injected into the muffler is not regulated by the valveA calibrated water injection fitting of 3.0 mm (.118 in) on carburetor-equipped models and 4.0 mm (.156 in) on DI models inside diameter limits water flow into the mufflerThe water flow regulator valve has calibrated spring and tapered needle which regulate the injected water in the tuned pipeCAUTION: Do not change the calibration of the spring, otherwise serious engine damage can occurAt low speed, water pressure in the supply hose of the regulator valve is not sufficient to overcome the spring of the regulator valve; more water is being delivered to the injection fitting at the tuned pipe
