If you have an impact driver and a torch you should be fine.
I will try to source a used one, and to be on the safe side also replace the rectifier.
My question is: what the hell could have caused this issue? Did the rectifier go bad and also fried the stator?
Yes, I would definitely wait until my charging issue is solved.You’ll probably never need a spare. You can list it here in the classified section, but you might wait a while to sell it. The FZ6 r/r is used on many Yamaha sport bikes, so if you list it on eBay, be sure to list it by part number, not as an FZ6 r/r.
What do I do with the extra Regulator?
Surely, I cannot return an open and used electrical part.
Try to sell here or ebay?
Retain as a spare?
@Motogiro
I have installed a FH020AA on another bike, and after some checking it turns out that I even have a new extra plug kit. At that time (few years ago) I also intended to replace the rectifier on the FZ6, but I couldn't find any reports of failed FZ6 OEM ones (unlike Honda rectifiers...) so I didn't think it was necessary. Now this incident certainly put a toll on the rectifier so it's certainly on the to do list.
The one I got in the past was allegedly from a low mileage BMW 1200GS, this time I will also look for a OEM one. After a quick ebay search it seems that now there are even more fakes than before, such as new FH020AA at 20 someting $ -yeah right!
Do you happen to have a pic with the FH020AA installed on the bike?
No, I have the Suzuki SV1000s. I have had to bypass a stator on a Honda CBR1000 that had the exact same plug burn out. I remember reading where the VFRs were having a lot of R/R failures. People were even adding aluminum to create extra heat sink for them.
Yeah all it takes is money but since I know a guy that does work on stuff like this I can justify a better R/R setup.
No, I was interested on a pic of a SH847 or FH020AA installed in a FZ6.Is this a question for me?
A request for a picture of the original Regulator?
Neither Rick's nor JP have my stator.
I found these two...

Why did I not buy a series one, aka SH847 ?
1- price: It would have cost me 2-3x more (got the FH027AA for around $55 shipped)
2-size: the SH847 is larger than the FH027AA, and the FH027AA is likely already bigger than the SH719AA (OEM FZ6).
3-honestly I'm not very convinced of the benefits. Please correct me if I'm wrong but IMO as the power generation works by spinning a permanent magnet, the stator is providing full current and voltage per certain RPM as long as the engine is on, regardless of the type of rectifier. Should the series one be a few % more efficient than the MOSFET shunt, it's unlikely that this would translate to longer life for the stator or any other electrical component.
I don't fully get it.The series type is only passing current when the voltage is below threshold. That means it is not being used as a resistive load that shunts current from the stator to ground. The stator runs cooler as well as the regulator.
I've seen Infra red photos of the heat difference with series regulation. That reduction adds to the entire engine. the benefit is there.
The shunt regulator must constantly use current from the stator and dissipate what energy that is not used for the bike/battery into the heat sink.
Easing the constant load on the stator reduces heat and and possibly hysteresis which might further alleviate additional mechanical force that could also contribute to winding insulator and physical breakdown. Motorcycle charging technology seems week when compared to automobile charging systems. There seem to be many failures on bikes in comparison and It's probably largely due to a weight saving system design. With today's solid state technology we can switch over to series and gain the benefit of long lasting, more reliable charging systems. The down side is more bucks for less heat.
This makes sense. Now, how would you calculateYes, as the the engine is spinning the stator is producing potential but it is not being used (no current flow in series)so there is no load and less heat.
