The Sport Bike Electronic Engine Kills (1-0263) were designed specifically for sequential firing 4 coil ignition systems like those found on most sport bikes today.  The kill time adjustment is set through the access hole in the top cover. Set time is from 50 milliseconds to 100 milliseconds. We invented the Electronic Engine Kill so we can offer our exclusive, no hassle, free repair or replacement lifetime warranty. Be sure to ask about that when buying copycat versions of our products. Custom wiring harnesses with a shifter/horn toggle switch are available as an option for some specific bikes to make wiring your MPS shifter a snap.
