Fuel Kill Box, Electronic Engine Kill - MPS 1


Fuel Kill

The MPS Electronic Fuel Kills are a universal application designed for use on all EFI bikes.  They momentarily interrupt the fuel supply to unload the transmission for full throttle air shifting.  They work particularly well for dry nitrous bikes to eliminate the pop between gears and they do not trigger the FI light. 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.
