Does the Lucas 200 W 16 amp single phase alternator produce greater power at a lower RPM than the stock alternator?

Thanks

Right now I am going to the same set up as Nigel. I got another 14.5A stator along with a Shindengen regulator and looking for a machinist to turn another rotor I have.Mounting the regulator is a tight fit but am making progress.
Are you going to the INOA national rally in Virginia?They are expecting over 275 bikes.It is in a very nice area right along the Blue Ridge Parkway. The DC chapter always puts on a good event.

It looks like a great time, I've stopped for lunch in that town a couple times riding through. A beautiful area.
I'm not planning on it this year. The whole work thing...🤣
 
The three phase I put in was Lucas. It’s been in there for maybe 20,000 miles.
From what I’ve learned the new Lucas is made by Wassel, it is branded Lucas
 
Single phase with a decent mosfet rectifier regulator makes a 3 phase pointless. The detail I have seen comparing the two stators paints an impression that they were maybe a bit liberal with the truth back then. Not surprising as they wanted to sell them, and if they were that good then we would have no single phase stators for sale today as owners would have converted their bikes but 50 years later we still have the single phase - says it all really.
 
I finally had time to get the bike out yesterday. Temp in the high 40s, low 50sF. First good test of the new 14.5 stator and new rotor with a Shindengen open regulator. To free up a few extra watts I converted to an LED headlight. Gerbing jacket liner and gloves worked perfectly. The 3 phase and Shindengen worked exactly as expected keeping up with the demand of the heated gear at anything above 2000 RPM as monitored by a Sparkbrite.
There's no way the single phase would ever have kept up with that demand.
Interestingly I used the heated gear while plowing snow with my open station loader this winter. I fitted an SAE connector and plugged in. I was impressed with the Gerbing gear keeping me warm out in the snow and wind.
I'm convinced the overheated stators I've removed were damaged by the shorting regulator Podtronics not by any interference with the rotor. There's no sign of metal transfer or rubbing just cooked stator. I don't see any need to machine a rotor for extra clearance as long as the stated min can be maintained. More clearance probably will just result in lower output.

If it works, it’s a win !

I am planning on riding down there, all registered. I road down there when they had the last one at Buena Vista. Nice riding down there and around there.

Jim,
Can you show how you mounted the Shindengen regulator?
Thanks,Mike

Mike, The only one I could find is the 50 amp model and it's freakin huge. It's mounted with cushion clamps on the down tubes low in front of the engine crankcase. It's way overkill for 14.5 amps. https://www.roadstercycle.com/ Has a PDF size template. He has the complete wiring kit with connectors. The cushion clamps I sourced locally. I mounted it with connectors facing up, wires running up the tubes. Connectors are waterproof so there's no environmental issues.
On this site Grant Tiller has pictures of stators damaged by mechanical interference and by electrical issues - shorting of the AC output. My stator damage was strictly electrical, cooked, but with no physical damage. I only recently came across this site: https://granttiller.com/alternator-issues
Too bad there's not a small one capable of handling 15 amps that would fit in the space occupied by the useless assimulator.
Jim
