All valid points Mr Vspec - I'm not convinced the bobbins are needed for the rectifier either and indeed HD replacement unit users also report no problems when solidly mounted.
Anyone know why these bike engines need such a mahoosive rectifier anyway? Cars have them build neatly into the alternator and they can be very small indeed. Do we really need a kilogram of electrical gubbins to control a relatively weedy 38amp output?
