On the carb the cable closest to the right side of the bike is the throttle cable and the one closest to the left side is the idle cable. Right about the middle between the two is the idle adjustment screw. It faces out towards the air filter end of the carb . The engine should be at operating temperature with the enrichener off to set the idle between 950-1050 rpm. Turn the screw clockwise to increases idle speed and counterclockwise to decrease idle speed. EFI idle speed is computer controlled.

Yes, you need to check your charging system. First remove the battery and fully charge it (overnight) then refit, and start the bike. With the engine running at about twice the idle speed check the voltage at the battery. It should be approx 14 volts DC. If it is lower than 12.5 you should look first at the voltage regulator and rectifier. The symptoms you describe lead me to believe your charging system is the culprit. It may also be be your alternator, but check the regulator and rectifier first (cheaper)
