@DEcosse posted a treatise a while back about how the design of the Triumph system has the stator working at maximum output continuously, and by changing out the rectifier/regulator to a series model, the stator only works as needed. If you make the decision to go forward, and you have the engine open anyway, you could replace the stator, and if doing so, I would recommend going with the series R/R (plug and play, though the location may need adjustment).
