The stock one doesn't have much in the way of fins. It's mostly a block of aluminum. If that was a concern, just bolt it to a small heat sink, using a little thermal paste between the two. A three phase system has a chunk for a reg/rec and they certainly have to be out in the breeze.

Ah, that is but one, of the two, regulators it has. You're looking at the DC side only with that one. The AC side is totally separate and only powers the headlight when the engine is running, requiring it's own AC regulator.
The XL600R was designed by a special kind of stupid when it came to the electrical system. It's a kickstart only bike, with one stator that powers three separate systems with different power requirements. An AC system for the CDI, another AC for the headlight, and a single phase system for the DC system to charge the battery that is required for the turn signals and horn to function properly, along with powering the tail and brake light when the engine isn't running (roadside safety). These three systems all share the same ground.
Part #7 is the DC reg/rec, and #3 is the AC reg.
Add a flux capacitor to that, and you can go back in time and ride with Charlie Sheen.
That's actually a XL350R, but, meh, same era. BTW, Fast and Furryus doesn't have squat on the car in that movie. The Ma-Sheen!
