Those are good readings. As good as mine after replacing the rotor and stator. I wouldn't suspect that you have any problems with those voltages. Maybe it's just a bad battery or maybe you don't drive it enough at an RPM high enough. It's been known to happen - to low (RPM), to slow. Take it out a ride again when you can (but not too far away from home) keeping the RPM around 4000 and then check your "off" voltage again. It should be the same as what you started with (13.1). I don't know though how long you'd have to ride it to make up for the energy you used to start it.
