A series-type regulator/rectifier would result in a much cooler stator, as well as a cooler running engine.
Stator cover which used to be at 96°C~104°C with stock shunt-type R/R, is now at 84°C~86°C with series-type R/R, while left cylinder head is at 92°C~96°C in the same ambient temperature... Stator cover temperature is now more stable at about 14°C cooler on average, and up to about 18°C cooler.
Do you have a radiator guard covering your coolant radiator?
Maybe it ran cooler because it had a rich stock fuel calibration?
