The Howerton Engineering Motorcycle Water/Methanol Injection System is designed to be a very small and versatile system. The system consists of a small pump and controller module. This system is a Progressive Pump Speed System, which means that the injection rate is controlled by changing the speed of the pump, not a PWM valve. While we prefer the PWM valve method of injection, this unit is extremely small and capable.
There are only 3 wires to hookup to the vehicle: 12V power(red), ground(black), and either the IDC or 0-5v signal(blue). The system comes with the pump, controller, posi-taps for tapping the 3 connections, and an inline fuse. Mechanically, the system includes a tank adapter, filter and compression fitting for the inlet hose. It also includes a jet adapter and two jets of your choice along with the inlet and outlet hose.
For a nice compact system this is one unit you should consider.
