It's not strange, that's just how all shunt type regulators work. By running the stator at full load at all times it is subjected to a lot of heat.
There is one possible solution that I am looking into, a series R/R that decreased load on the stator when it's not needed. The problem is that there are no OEM options for 3 phase ones, but there are at least two aftermarket companies offering them for the Harley Davidson market. Compufire and somebody else.
