If the generator and regulator are good then you should have around 7.5 volts with some revs up, around 2000RPM and hold for a minute or two to allow the voltage to stabilise. Approx 6.3 volts is the voltage of a charged battery at rest. so you see the battery is not being charged if all you have is 6.5 volts. Test your battery with a hydrometer or have it load tested and make sure it is not overfilled. Regards, Kevin.
