Quickly remove and eliminate the OEM key switch. Simple plug in installation, the fuel pump kicks on and pressurizes the system with a tap of the start button.
 
A key eliminator is not the same as leaving the key on; bypassing and eliminating the key rerouted. OEM switch directly pushes battery use; while the key is on the fuel pump powered up. This is why you kill the battery when you leave the key on.
 
With the eliminator installed the power to the fuel pump is rerouted through a relay already on the bike that is activated when you tap the start button.
