The water flow regulator valve is mounted directly
onto the muffler.
SPX MODEL
1. Water supply hose of regulator valve
2. Regulated water to injection fitting
3. Water injected into the muffler
GSX LIMITED, XP LIMITED AND GTX LIMITED
1. Water supply from tuned pipe water jacket
2. Regulated water to injection fitting
3. Water injected into the muffler
NOTE:
The water injected into the muffler is not
regulated by the valve. A calibrated water injec-
tion fitting of 3.0 mm (.118 in) inside diameter lim-
its water flow into the muffler.
The water flow regulator valve has a calibrated
spring and a tapered needle which regulate the
injected water in the tuned pipe.
At 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.
LOW SPEED OPERATION
1. Water entering regulator valve
2. Water exiting regulator valve (less restriction)
3. Water injected in the muffler
At higher speed, water pressure increases in the
supply hose of the regulator valve and gradually
overcomes the return spring of the regulator
valve. Less water is being delivered to the injec-
tion fitting at the tuned pipe.
