I just installed an 11 pole, GEH. Yours is absolutely the AC version. Here is what I did: First, I cut off the connector that has the 3 hot wires, and the ground. The power output wires will either all 3 be yellow, or, as mine was, a yellow, a white, and a pink.
I kept the stock R/R as is, to charge the battery. I installed a 7 wire R/R right across from it. I just spliced 2 of the lead wires, where they go to both reg's. The 3rd wire obviously goes to the 3rd lead on the 7 wire reg. The other 2 wires go to both regulators. This is perfectly fine, because you are not going to put any "strain" on the stator. They produce what they produce. You either use it all, or you don't. What you don't use get's shunted to your frame, which almost certainly has to turn into heat, the way I understand it. Most of the 7 wire reg's are really 6 wire. They will all have 3 hot inputs, plus a ground. Get one with a red and white wire coming out of it. There are some that have a red and a black wire. I am pretty sure the black wire is a "monitor wire". I like having the red and white wire, because both of those are DC output wires. I used the red one to run 1 50 watt LED headlight, and one 13 watt LED headlight. I used the white wire to run an LED taillight, plus another 55 watt headlight that I only use on really dark roads. I know, I know, that's a LOT of light, but I have some Tim Allen in me. Having the 3 phase regulator run your lights is great, because it is "full wave", which doesn't dim hardly at all at low RPM. If you run it as I have, you don't have to have a switch to your lights, and worry about switching them off when you park. They cut on when you fire her up, and they cut off when you cut her off. If you want to keep your high/low beam switch on your handle bar, you can use the white for low beam, and the red for high beam, or vise versa.
I cut the connector off of the 7 wire regulator.(get one that has actual wires coming off of it, as that makes it MUCH easier to tell what goes where). Get a couple of packs of the weather resistant bullet connectors, and you can crimp those on wherever you need a connection. If you need any help with this stuff, pm me, and I'll give you my phone #, and you can call me. I just totally rewired my scoot, and am still working on it a little. You have been very helpful to me, and I will be happy to help you out with this.
Another thing, an 8 pole flywheel will work fine with the 11 pole stator. I know this for an absolute fact. You can find an 8 pole flywheel for pretty cheap. Basically, if the stator will fit inside the flywheel, it will likely work.

Do ya'll know if they make a 4 valve head for a 50cc?

I cannot think of any reason why that wouldn't work. That's a really good idea. Definitely let me know how that turns out. You saw my other thread where I am not quite happy with the 1500. I think you are on to something.

Harbor freight sells a tire thingy(that is the technical term, LOL), that works on tires up to around 12" for like $30, maybe less. I am going to buy one when I have to replace my tires.

I just ordered an A9. It looks like the 9 & 11 are by far the best. Unless you are racing, you can disregard everything past 8000. If you use your scoot for transportation, like me, you don't even want to get it up to 8K much, if at all. If you can get an 11 for the same price, do it, as it appears to be very slightly better in the usable RPM range. If it is much more expensive, I would just go with the 9.
Does anybody know which one the stock cams are closest to?

Keep us posted, GEH. Sounds like you are chasing perfection, like me. It's a never ending quest, isn't it?
In my technically challenged mind, the torque spring works the RPM much different than pulley weights. That stiffer spring seems to inhibit the belt from climbing up the pulley on the variator. It is always wanting to close, so you can't get enough tension to let the belt climb, IMO. I didn't think about letting the spring break in. It just seems like it is constantly closing up every time I start to get momentum. I think I'll try a 1000 spring next. I wish they made them in 500 increments. I think a 500 spring would be perfect.
I think the 1500 would be optimal for a hilly area, like somebody posted. I bet they increase the torque of your rear wheel a ton, thus save wear on the engine. GEH, let me know what you come up with. Thanks.

I installed a 1500 torque spring in my clutch. I timed the acceleration, and from 0-30mph, the torque spring slows me down about .4 sec. IMO, the torque spring does just that; it increases your torque, but it makes your scoot like a diesel. High torque, slow acceleration. It opens every time you start to get some momentum. It does probably save your engine some wear in hilly areas, but it decreases performance, in my case, at least.
Thoughts?

Thank you very much. I have been really eyeing those, but did not want to have to bore the case. You are the man.

Alright, thanks to all. I have learned several things during this ordeal. 1. It'stheride members are a very knowledgable, kind group. 2. Ask BEFORE you do something. Engine work is not like dealing with women. It is NOT better to ask for forgiveness, than ask for permission. 3. Blowback is real, and it, well, blows.
I ordered my BBK from one of the lower priced places. They are not "bargains", they are cheap. I ordered just a cylinder, that cost as much as the entire BBK I installed, and the quality difference was remarkable. The cylinder on the cheap-o was as thin as a coke can. Order from NCY, Scrappydog, Scooters-to-go, and some of these others that have banner ads on here. Trust me.

Thanks for all the responses!
Just to be clear, I did replace the piston, and rings. I did not replace or hone the cylinder.
I am going to take it all back apart, and install as gasket. I am going to look in to how to hone a cylinder. I spose I'll either do that, or buy a new cylinder.

It only has about 30 miles on it, and I put a new piston, and rings on. I just didn't hone the cylinder. I don't know what that is. Should I order a new cylinder, or do you think it's OK, with a new piston and rings, and only about 30 miles on it?

I got it started with the kick start. It just won't turn over with the starter. It would turn over on the other engine, which is identical. Only difference is no gasket. I know shaving a mm off of the head will increase compression a lot. I have no choice. I'm going to put a gasket on it. Will report back.

Start by testing the ignition key switch. Easy place to start, and if it is the switch, it's an easy fix. You should get no continuity between the 2 wires when it is off. And continuity when you turn the key. I can't remember what color the two wires are you should test. Probably black and red. Pull it out, and tell me what color wires you have. Do you have a multi meter? The $5 job from Harbor Freight will do fine.

They sell an oil radiator cooling unit for 50cc-150cc GY6 scooters.

So the key broke off on my crankshaft. The one that sets the flywheel. I have a backup engine, with back wheel attached, so I transferred the new BBK over to that engine. I did not have the gasket that goes between the cylinder, and the crankcase. I don't think that's the head gasket. Anyways, now the starter won't turn the engine over. It's a brand new starter. Is the compression too much, because I didn't use a gasket? I just put some RTV silicone on it. I have a sheet of gasket material. If I cut a gasket, and put it in there, will that reduce the compression enough for the starter to turn the engine over?
