No shut off?
Probably won't need any shut off. None of the car systems I work on have any kind of tank shut off and run a pressurized fuel tank/ evap system (fuel cap puffs out at you on removal). Injectors rarely leak with full system pressure on them so should be very safe from just a gravity feed with the bike parked. I would use an extra straight coupling in the supply and return hoses somewhere handy between the tank and the next component to allow the use of clamps to make tank removal easier.
I have adjusted my idle mixture richer but other than that will probably just ride the bike stock for the rest of the summer and then go after the fuel injection/ pipes as a winter project.
