Here are the voltages as best as I can measure them with the equipment I have.

Bike: 2010 F650GS
Bike was idled for 10 minutes before readings taken
Meter 1 (red): AMPROBE PM51A and according to their spec sheet accurate to +- 2%. (brand new and bloody expensive by my standards)
Meter 2 (Yellow): Digitech QM-1525 (old, cheap and shitty)
Ambient temp: 25 degrees C
Installed Battery: Shorai LFX18A1-BS12
Idle Voltage: M1 - 14.1v, M2 - 14.01v
3000RPM Voltage: M1 - 13.99v, M2 - 13.9v

Lower voltage at 3000 RPM compared to idle seems odd.

Proof of test pics follow.

M1, Volts at idle

M1, Volts at a tad over 3000rpm

Meter comparison at Idle
