How did you figure that out? Might be a dumb question, but did you find any charts on hardware sizes/make your own? Or did you just measure one? I'm trying to get a system down. An order of operations and a step by step process to making a motorcycle restoration faster, and more complete.
The second series in the number. XXXXX- 06012-XX . The first 2 digits are the diameter. The last 3 are the length.

I'm surprised there isn't Marty.
Glad that it wasn't a dumb question!
On the specials just 2 short 12-16mm long ? m6 hex head bolts up into the triple from below, the heads sit inside the recesses. usually a 10mm socket on a long extension to get em in.
These show it pretty good.

Someone used to have a decal for that. I don’t remember who.
Doing a lot of cleaning today. It takes a good bit of time, but it's really paying off!
Wondering if the reg/text were originally a brass-ish color? I just went with a scotch brite sponge, some good off, and 1000grit wet sanding to finish it off. Looks a lot better on the bike now.

Looking good! Yes they were yellow zinc chromate plated originally.
Edit; Were prolly cadmium plated but the usual replacement is yellow zinc

Will they rust if I leave them be? Or was it just the way they decided to finish the parts?
They weren't a very robust coating to begin with and now you may have polished any remnants away, lol. So, keep an eye on it, it could start rusting on you and require some clear paint. But, truth be told, that's a component you should consider replacing and upgrading. Many of us switch to an automotive regulator. They're cheap, very dependable, and give a more consistent output .....
Cad plating is all about rust protection. see revision and link in post above.
Ready, fire, aim. LOL

Twins, where would I get one of those? Would it require harness connector modification? Is it a reg/rect. In one? It's an interesting tidbit of info.
It's a VR115 (or equivalent), used on many old '70s Chryslers and Jeeps. They are available at most auto parts stores for around $30 but if you're not in a hurry, you can usually find one on eBay for less. Hook up is pretty simple but requires a little "jumper" harness. In other words, it won't plug directly into your stock harness. But with the "jumper" harness, you don't mod your harness at all. It allows the mismatched plugs to mate together .....
This is a regulator only. We use another aftermarket replacement for the rectifier. If you do a search here for reg and rec replacements, you should find lots of info. Lots has been posted about it.

Do I see a custom mounting plate for the reg? That's a pretty good set up.
Is the main benefit to this replacement JUST reliability? Does it give a higher output than stock?
I wish I'd known that the originals are usually replaced... I'd have not wasted time polishing and cleaning.

Yes, the VR115 mounting holes don't match up with both of the originals so a simple triangular shaped "extension" plate was made up to make the 2nd point match .....
To figure out what the size, shape, and hole locations needed to be, I cut a template out of card stock .....
As far as the benefits go, the original is quite reliable, it just doesn't have a "smooth" or steady output, it bounces all over the place. This is probably because it's a mechanical unit with contacts inside that open and close. I think this bike's vibration messes with that. The VR115 is solid state with no moving parts inside so the vibrations don't seem to affect it. It has a nice steady voltage output. It doesn't really produce more voltage, you don't want that. The system is designed to have a charging voltage output about in the low to mid 14's. This works best to keep your battery charged. That's what the VR115 will give you. Mine gives me this right after starting and then after a few miles of riding and the slightly depleted battery (from electric starting) has been recharged, it drops off slightly to around 14.

No need to fix what ain't broke. XS650's have and continue to run millions of miles on mechanical regulators. I kinda like being able to set a charging voltage based on usage. 
If starting from scratch I'll use electronic, but if it's still mechanical I don't swap them out.
