FWIW,
The output of 12.3v is showing something wrong when charging for sure. Oregon is correct with the cell measurement. I instructed that each cell output of a good battery is 2.125 by theory.
Continuous-preservation (float) charging: 2.23 V for gelled electrolyte; 2.25 V for AGM (absorbed glass mat) and 2.32 V for flooded cells.
Your charging should be at 13.92 for a lead acid battery. When loaded the voltage does not matter as much as amperage. You seem to have the voltage close to charge when no load but how about the amps? Amps are required under load and without your voltage will drop and continue to drop until the battery is dead and if the stator can not supply enough to keep it running without the battery then it will stop. I would question the shop if they told you it was ok to have 12.3v running with headlight on.
I would check the regulator/rectifier as most motorcycles charge at 14.4 and should maintain this at idle with the permanent magnetic generator system.
