Either one of you seen a Transpo (

No? I didn't think so.
... as to clueless: I work all day as an automotive electrician, you know; fixing starters, alternators, sometimes repairing (at the component level) rectifiers and those things that limit the field on those power generation thingmes... OH YEAH, VOLTAGE REGULATORS, going on 20 years now.
What do you bring to the table, besides some lame sarcasm?
So, I will stick with my suggestion, just trying to help out you see, of advising the OP that "Any auto electric shop has access to hundreds of generic regulators, ALL for a lot less than $100." ... and yes,
some of them WILL work on a bike.
If you want to spend $100 on a $25 part, by all means, go nuts.
