NC30 R1/R6 Rectifier modification

Pretty sure most new bikes come with FET devices magg. Certainly the R1 and the ZX10R post 2004 are MOSFET units. Same with the ZX6R and CBR600RR post 2007.
I looked into it because my trumpet had an old shunt type unit. Luckily, mine failed just as Triumph announced a recall on all bikes running with the SCR devices. They've replaced them with MOSFET units now.

What both Magg and I are saying is that FET is still shunt. The difference is really scr vs FET shunt. In scr shunt which is our stock ones a lot of every is dissipated at the rectifier ~14w . The FET shunt will dissipate ~1W making a huge difference in temperature at the regulator.

The rest of the energy is dumped through a resistor or the stator itself leading to those components getting hot (or hotter if using a FET shunt.).
