    First define what is "Normal" & "Excessive" current draw.

    You may want to load test the battery.

    Sounds like your going by the dash gauge. Measure the voltage at the battery with a quality handheld meter and you probably won't see those numbers. Zero to eight volts?,,, even a carb bike would probably not even run.
