Introduced in 1994 the original Jetworks Flow Control Valve greatly improves bottom end response for racing or while re-applying your throttle during freestyle maneuvers. This is done by drying out your water box at low rpm and idle speeds. Without a flow control valve water fills up the water box and exhaust hoses, upon sudden acceleration all of this water must be forced out quickly before full exhaust flow can occur. This can cause a craft to feel slight hesitation and/or sluggishness, easily adjustable by turning the hex portion of the valve. We have sold these to every Factory Team during the 2 Stroke Racing era including Kawasaki, Sea-Doo, Yamaha and Polaris. They even came factory equid on some Factory Pipe Products Exhaust systems and OEM on Polaris Watercraft. Used by many, recommended by all, the Jetworks Flow Control Valve is the best and most noticeable performance upgrade for the price.
IJSBA race legal.
Can be installed on any aftermarket exhaust system by using the water fitting on the stinger.
