But in case I do want to put together a 10A charging kit (works with my current flywheel - if I get the large magnet flywheel, it would do 16A out of the exact same hardware), here is what I will need:
Used 592830 stator, this one came off a Vanguard V-twin but it is the same as what I would need, and is only $28:

Voltage regulator, P/N 845907. This one is used and only $19.81:

After that I simply would need to wire the single 10A DC output into the wire that normally feeds the battery. Hopefully it can carry 10 amps. Now I'd be charging the battery at up to 10A, regulated (not sure what output is, maybe 14V?). Anything else I could hook up to either the battery or possibly the ignition switch. Not too complicated really. I could rewire my existing headlights to connect to switched battery power so they'd be bright all the time or add the LED lights (probably not both on only 10A - still needs to be able to charge the battery).
Maybe I should add the DC pigtail so I don't have to cut and hack as much.
P/N 692306. $13.94.

Yellow connector, P/N 399916, $4.99:

So about $67 to convert. That is really not bad. This gets me 120W total theoretically (12V * 10A). Some goes to the battery but otherwise free to do various lights. And with this type of charging system, the lights would be battery voltage regardless of RPM so more like a car. And if I locate a flywheel with the large magnets, the output jumps to 192W total. Rear lights....oh yes.
The alternate plan is two of those converters @ $13/ea. So $26. Less power, less invasive install (mainly not having to pull the flywheel and swap stators). Lights bright only at max engine RPM. Not sure about reliability and I don't think these are weather rated. Less than $62 but honestly at these prices the money is not the issue. It's more...what do I want to do?
Decided to do this because, well, I enjoy tinkering and it will give me some cool options in the future with a regulated charging system (lighting, sleeve hitch with electric actuator, electric actuation retrofits to my snow thrower like chute rotation and/or tilt, etc.), so I went ahead and found all these parts on eBay. And I did better than the prices I originally found. Recap:
Used stator, $20, $8 cheaper than before: https://www.ebay.com/itm/Briggs-Stratto ... 2749.l2649
Used voltage regulator, $11, $9 cheaper than before: https://www.ebay.com/itm/Voltage-rectif ... 2749.l2649
NOS yellow connector, $5, same as before: https://www.ebay.com/itm/Brand-New-NOS- ... 2749.l2649
NOS DC pigtail, $9, $5 cheaper than before: https://www.ebay.com/itm/New-Briggs-Str ... 2749.l2649
So before it was going to be $67 before tax. With the new prices I got everything I need to convert to a 10A regulated charging system for $45 before tax. Now that's pretty cheap. It helps that these parts seem to be interchangeable with charging system parts used not just on some opposed twins, but some later V-twins, so they are plentiful.
