HELP PLEASE 81 cb750k

sccustoms
having electrical and firing issues at all speeds.
first battery will not charge. have put new regulator and rectifier on. used (3of these) stators - new rotor - used (but good) starter relay still will not hold charge havent put a new battery on since the last 2 stators. but this battery is only about 6mths old.
second - the bike runs like crap sputtering  missfiring - checked firing all looks good plugs are new ngk plugs - i attribute the bad running to bad battery. am i right or wrong. when it gets into fifth top speed is 60-65 mph thats at full throttle and bike levels off exhaust sounds even. assoon as you hit a up hill puts pressure on it goes to sounding like crap again. is it time to rebuild it has 80 thousand on the motor. any suggestions im up for anything. oh 1 more thing the exhaust is removed and im running open pipes out the exhaust ports. could that be contributing to ruff running due to back pressure. i havent checked compression yet (dont have a guage yet) thanks.
