I just finished removing and re-installing the underbelly (coroplast) on my Bullet. It is a PITA but unless you know approx. where the short is it would be hit and miss. The factory used some black expanding foam to TRY and close air gaps. Once the screws are removed sliding a putty knife between the frame and coroplast will release it.
If you have the time while you are there double check all the tank level connections. I found several loose. Good time to check out the duckwork also.
I wouldn't be a fan of making sections out of it unless you have a way of overlapping the sections when you put it back together. I don't trust tape.
My only warning would be to watch for short screws when taking it down. Those short screws are located where a tank is installed over them. They need to be replaced in the same place they came out of. If you put a regular length screw back in you will puncture the tank. Please don't ask me how I know!!!!!
