This Jetworks pro flow control valve provides improved throttle response and much quicker starts by drying out your waterbox at low rpm and idle speeds. Tests have shown an average acceleration improvement of 10 feet over a non-equipped model in the first 50 feet.

The flow control valve allows unrestricted water flow to the stinger for better top speed, yet controls the amount of water at low speeds for better response. This will not interfere with normal engine or exhaust pipe cooling and is compatible with all electronic water injection systems.

The spring tension is adjustable in situ by turning the outer housing and testing with a pop off gauge. 

Race Legal for All Classes.

NOTE: Compatible with aftermarket exhaust systems (e.g. Factory Pipe) and all OEM exhaust systems except Yamaha.
