If you run direct 12v battery power to the fuel pump it should run and the bike should run as well. If it does not then you will need to diagnose further to see if it is the pump or something else.
Try gravity feeding the carbs to see if that makes a difference.
Elevate the fuel tank and run a hose directly from the pet cock to the carbs. It would starve for fuel at the higher RPMs but would idle and rev just fine if there are no other problems.
That would let you know if there is a problem on the fuel delivery side or on the carb/engine side.
