EDIT 7/12/2016:
The GS Resources Stator pages have been updated in 2016 by Frank and so I have removed the previous discussion of the GSR bias toward promoting Electrosport products. I still personally recommend teh stators assuming production continues as it has. The R/R are a definite thing to avoid.

The biggest change to Permanent Magnet (PM) alternators for motorcycles is the availability of SERIES v.s. SHUNT R/R's. Most of your metric bikes have 3 phase PM Alternators (like the GS) and traditionally these have all be fitted from the factory with SHUNT R/R's. As technology has advanced the SERIES R/R has emerged which is a night and day difference for your charging system especially as far as your stator is concerned. Less heat generated, Longer life for both stator and R/R and few burned connector. The only drawback had been price, as the after market was the only source of these retrofits. The SERIES Shindengen SH-775 has now emerged from the OEM market with a low price reflective of the mass markets.
SHUNT_vs_SERIES_RR_Compare_Tutorial
There are really few compelling reasons in this GS day of electrical charging to buy anything other than a SERIES R/R. The SH-775 is a very affordable Series R/R and can be purchased cheaper than most conventional SHUNT regulators. They are typically $70 new from Polaris dealers.
See this link for a summary.
GS Stator
It should be mentioned that some SHUNT regulators having been working for years, but that is generally limited to the smaller bikes that don't have the same heat problems as the bigger bikes. For anything at 1000 cc and above a SERIES R/R is a must. 750 cc is borderline I have little experience on bikes below that but there are many reports of no issues.
It has to do with heat dissipation and the SERIES R/R just doesn't create the same heat in the stator as the SHUNT R/R will. Yes I said stator heat . Also if you plan on going to LED lights and reducing your electrical loads you will further stress the R/R.
I have reordered the options based on my assessment of likely need and austerity of the audience. I have pushed the Honda 6 wire to below all the readily available SERIES R/R's. It has been a venerable workhouse R/R for many years thanks to it's champion Duanage, but newer SERIES technology has put this R/R past it's prime.
WARNING: Shindengen is mixing both Shunt and SERIES R/R's with the same SH prefix.

#1 The SERIES Shindengen R/R SH-775 commonly available from Polaris Dealers. Search the GSR site for recent posts on best price and availability. This is most peoples number one choice for an R/R replacement because of low price, easy availability and SERIES performance. It's only down size is a fairly large form factor (same as the MOSFET FH012) made even larger if you use the mating convectors.

#2 The SERIES Compufire R/R CF55402 (only part number applicable to 3 phase PM alternators like GS Suzuki)
The Compufire is my favorite as it is the smallest SERIES R/R available here in the US and is a MOSFET SERIES design which results in slightly superior performance to the SH-775 in terms of lower power dissipation, higher (low RPM) output voltage and lower OFF state current draw.
General results should apply to any SERIES R/R not just the Compufire.

#3 The SERIES R/R's from CycleElectric (600 line; there are several 3 phase models)
The CycleElectic which is an older design and uses SCR's is capable of 50 amps ; It is also the largest.
#4 If you don't want to buy one of the SERIES R/R's above (It is possible you just don't have the money and for smaller CC bikes with less cooling issues it doesn't matter as much) The Honda(or equivalent 6 wire R/R formerly sold by Duanage) is your best SHUNT design R/R.

Regleri: No promises here as I can't even read the website, but apparently this company in Croatia makes series R/R's. The schematics of the SCR's on the packages make it appear as if they are opening the circuits and are in fact SERIES v.s. SHUNT. They do specifically list one SHUNT R/R .
Apparently it is a combination(SERIES then SHUNT R/R) , SERIES at low speed when voltages and timing are slower and goes to SHUNT at high speed presumably because it cant manage SERIES over 8K RPM.
And some fake SERIES R/R's (STAY AWAY)
None of the Electrosport products have done little to improve the stator thermal problems with SHUNT regulation.
In fact the only thing the Electro sport R/R is better than is the old single phase regulated shunt R/R's like the one I had in my 1981 GS750E.

There are even MOSFET R/R's commonly available which are better than the Electrosport SCR shunt R/R. See these listed in Matchless's thread on R/R part numbers. The MOSFET (is still SHUNT) will get less hot that an stock/electrosport SCR R/R , but it might make the stator a little hotter.

If anything the stator pages series has gotten more convoluted and less accurate. They have not even corrected the Phase A or Phase B test descriptions.

p.s. I also just found while searching EBay and cross-referencing OEM Parts Fiche that SeaDoo and CanAM also use this same Shindengen SH775 Regulator under their OEM part number 710001103.
Now - the new price is about 2x that of the exacts same Polaris OEM part - even from same common dealer!
But there are a lot of used SeaDoo/CanAm SH775 on Ebay (although still about the same price used as a brand new Polaris-sourced part)

I'll review and then we can ask Frank to replace the Stator Papers completely.
