Friend of mine has a marine alternator small enough to fit the bike.
It is a one wire self exciting alternator, therefore only one wire connection from the alternator to the positive of the battery.
Would this be suitable should I decide to use it. Meaning disconnecting the three yellow wires from the stator and running one positive lead from alternator to battery.
If you can get it to fit, sure. Some people leave the yellow wires disconnected, and in case of alternator failure, just reconnect the yellow wires to use the original stator as a backup reserve.

I went with the nippendenso alternator for a 92 geo metro,hooked up main wire to battery, with 50 amp inline circuit breaker,1 power wire to turn it "on" with key on,(I used accessorie at fuse block)and 1 wire to sense voltage,plugged in to harness at regulator plug(no regulator needed,alternator has it built in.)Works great.

Fantastic thank you for the info.
Couple more questions, is there any reason why everyone is using 50 amp alternators? Is there any advantage or disadvantage to going to a higher amperage? Also does anyone have a link to where I could by just the brackets for the poorboy conversion? I know I could make my own but it is just that I do not have the time. Locale shop was suppose repair the bike but it has been a month and nothing is done ,,,,,,,,,,SO!!!!! I have to do it myself

Not sure what amp my alternator is,but I found a post on here awhile back that suggested 50 amp circuit breaker inline on charging wire.As far as brackets, I just used 1x1 inch angle steel mounted to left front motor mount, flat steel under faux tank with adjustment tab welded to it.There is a video on this site you can watch and get a really good idea on how to set up brackets.Good luck on your project, took me about 4 hours and I also installed volt meter,my digital dash doesn't have a volt gauge.Ran volt meter off accessorie power also,so turns off with key.

personally I don`t see the need for anything higher than 50 amp alt, no power windows power locks power seats
windshield wipers heater motor or air conditioning or rear window defrost on our bikes to require a higher amp alt.
just my opinion.

Assuming you are running your bike stock. Many owners want to add aftermarket equipment. Things like lights and heated clothing draw lots of power. Also, running an alternator at a lower load than its capacity (i.e. only pulling 40 amps from an 80 amp alternator) is a good way to ensure longevity of the alternator.

Has anyone come up with a permanent fill for the old stator wire hole on the back cover?

My vote would be J-B Weld. I'd use the quick-set version, build a small form on either side, fill it in, and remove the forms once it begins to set.

I just left the plug right in engine.separated all 3 wires and deadhead them so they can't arc,and tape them up. That plug is designed to seal for years,why chance making a plug that in all probability will leak and if unnoticed on a long trip,take out your engine. I try not to create a problem where none exists.

I am permanently removing the stator, still have the plug but without the wires guess i will get creative.

I wonder if there's enough thickness there to thread it and use a pipe plug and thread sealant?Like a truck transfer case drain plug?

I was thinking the same thing, I will follow up on that idea.

Looking to do the conversion on my 1985 Honda Goldwing the only thing that I am not sure of is the pulley on the crankcase where can I get that pulley or how can I get it

Try searching RDG UK 4" pulley. They have one with a 12mm bore. They are in U.K. But do ship to North America. The pulley is aluminum with V grove. Shipping takes 2 weeks. You can use it with a mini denso alternator.

I used a power steering pump pulley from an '85 Prelude. 4" and works well. You do have to file a bit as the bore has a flat spot to keep it from turning on the shaft. Once you round the flat spot, it is a friction fit.


Here is what the crank pulley looks like after install:
