I've found the BGM regulars okay and I tend to opt for them, I don't know why as the cheap SIL and ones seem to work fine. Despite any possible output improvements with higher wattage, I can't really see a need for a better stator, unless you are putting on a D.C. cigarette lighter output somewhere. I use an LED rear light and a quartz front light and everything works great whatever the stator whether it's a SIL or BGM. The BGM ones seem and look better made.
I get the KISS point and can't be bothered with batteries, better spark gizmos and even reed valves, just more things to cause problems.

Its Lambretta Tuning group on Facebook/Anthony Tambs new 180w 3 phase stator he's testing.
He does 120w versions that are supposed to be good (im on the first version BGM did DC that has been all good which i run with an originally indian heavy long fin that has had the fins trimmed to short length and also midweight)

The story is that they are kinder to the stator, because they don't dump all the unused current. They use jiggery pokery to control current.
The story goes they also charge better at lower revs, and more stable at higher outputs. Increased reliability too. Plug and play with most modern bikes
Win win so far.
The downside is they don't cost £30. But the real ones (beware of knock-offs) are properly made.
Shindengen FH020AA is the most used one I have read about. Although much talked about in certain bike circles, I haven't heard mention here or on another scooter site.
The Yamaha P/N is 1D7-81960-00-00. There are several people selling them as kits to fit to other bike and also monster, multi amp versions, probably for welding.... to fit to your Hardly.
Yes, the mosfet ones use pwm (pulse width modulation) well not exactly but close enough for pit work. And pretty much everything you say is right with these caveats/ additions:
You can pick them up for £30 ish from eBay quite often. I've done 3 conversions on aprilia v1000s which have utterly s**t electrics. The only other thing to note is that they are 3 phase and all (except Anthony tambs' new one) lambretta stators are single phase. You can still use them but you'll only get about 55% of the rated power. That said they're usually massive compared to ours; 500 to 650w typically.

hendy i got a tingle down my back when you said that ( pulse width modulation )

Aye, our lass likes it when I say that during 'the act' especially if I say it in a Mexican accent.

Exciting to know!
The 500\650w regulators as per hardleys are a different breed altogether, the one I quoted is around the 20 amp mark, and quite small - still all irrelevent on single phases - unless someone knows better.
Even Joe Lucas had three phase charging.

Working DC without battery sounds interesting and is something that I'll consider as it is the battery that ruins it for me.

That one appears suitable for an r1. I'm too lazy to look properly but an r1 needs big power. Also, 20A means a lot of different things; is it max, rated constant, ac input or dc output? I know I sound like I'm trying to be smart but these really do vary from one spec to another and mean wildly different things.
You can use a 3 phase regulator on a single phase system but it won't deliver the power it's capable of. Doesn't really matter though as the alternator can't deliver that much nor does the system demand it.
Also, what is "hardleys"? Predictive text?

Ah ok, I had an initial reply from him but then couldn't get anything after that despite saying "TAKE MY MONEY" . Shame as I really prefer to support local small run guys like him whenever possible.

I know few people that run a lithium ion battery without issues but then again my other bike sits for about 8 or 9 months without use and a few hours on a charger and it's all good but I use maintenance free AGM batteries.
