I've been doing some homework on the regulator issue and thought I needed to update you all on the findings. I sent an email off to
www.Roadstercycle.com asking about the newer Shindengen SH847 series regulator and comparing it to the very reputable SH020AA shunt regulator currently available. Here's the email and the response I received. It looks like the SH847 is working beautifully keeping the stator running cooler and so far 500 units out there working without problem. I would jump up the extra dollars. for the SH847 before spending the money on the FH020AA.
Hi Jack,
John Eplett here. I am a moderator on
www.kz1300.com as "Kawboy" Our members upwards of 1400 all around the world share a common interest in the 1979-1989 Kawasaki KZ1300 Z1300 ZN1300 6 cylinder Kawasaki's. We have a few common problems one of which is an issue with frying stators and regulators/rectifiers. Some of us more knowledgable have switch to MOSFET style regulators and have reasonable success although the issue with frying stators still exists.
My question to you is "What is the difference between the FH020AA and the newer SH847 and will it rectify our issue with frying the stators once and for all?" It's one thing to talk our members into switching to the MOSFET design but if by going the "extra mile" and going straight to the SH847 to be finished with this problem of ours is the way to go, I would advise our members and send them in your direction. I like to try and keep up with the new technologies. In attempting to research the diference, I find no available information. I would really appreciate it if you could take a moment and provide the information I seek.
sincerely,

Hi John, The burning stator issue can most likely remedied with the SH847. It is a series R/R that runs the stator cooler. I have about 500 of these out there now on problem children like the Rotax Buell and Aprilia motorcycles, they are a stator eating nightmare but the SH847 has been great on these. Wether it’s the Holy Grail or not is yet to be seen but at this point it’s been the stator saver. About 500 out there with no issues.
The SH847 is a series R/R that has a 50 amp continuous rating. We use it on race bikes that unplug headlights as it will destroy a normal shunting R/R doing that. Also on bike where they change all the stock lighting to LEDs as that also wreaks havoc on a stock type R/R as then they have to get rid of all that extra wattage not used in the bulbs and overheats the R/R.
The SH847 is bigger than the FH020AA Mosfet so you will have to do some mounting homework. I’ve sent a PDF so you can make a cardboard cutout for fitment trials. You should be able to print it out 100% and be the correct size but measure it to make sure. I do have adapter brackets and also make custom ones if needed.
Hope this helps your guys out. Those 1300s are hard to find in the states, I’ve seen one once.
