Bypassing the controller is great to get a bike home but it is not a good idea to run it bypassed long term. This is a single ended fuel system and the controller, along with a fuel pressure sensor, regulates the fuel pressure. Older systems have a mechanical regulator and send excess fuel back to the tank and this fuel also cools the pump but eventually it heats up the fuel in the tank and it gives off more fumes. They came up with the single ended system to eliminate the fuel in the tank heating and polluting the air. When you bypass the controller the fuel pressure is what ever the pump can put out and excess has no where to go.
