Ignition Kill Box - for air shifter application. This is the only Ignition kill specifically designed for use on the new 4 coil sport bike ignitions. The simple design provides for a simple installation. The kill time, the amount of time the engine "stay's dead" between shifts, is easily adjusted from 50 milliseconds to 100 milliseconds via a small pot accessible through the access hole in the front of the unit.You can use this as a kill for the electric over air, air shifter, or with a brake light switch connected to the shifter, that will allow fast and consistent full throttle shifts without wait, by simply pulling on the shifter
