As far as I know, that's normal.
A friend on a trip to France on a VFR750 once noticed how hot his regulator was running - just checking things over at a petrol stop. He wanted to call the RAC immediately.
Instead we found a Honda dealer who very helpfully gave it the full test and said "all OK - yes you can burn your finger on one if you keep it there!"
He rode that bike another 4 years or so with no problems.

I've never done such a 'finger test' on any of my bikes. Usually there's so much stuff to remove before you can reach it, it would have cooled down anyway.

But it's always a good idea I think to make sure nothing is blocking whatever airflow around it that the manufacturer has provided. Like bits of luggage squeezed into nooks and crannies.

I think thats why they put cooling fins on the later ones , cos they get hot and the fins help dissapate the heat. That would be my thinking.

Ok……when your battery is fully charged and the bike is using less power (keeping it simple) than the amount of power being produced (with me so far ), then the excess power is converted to heat which is dissipated by your reg/rect.

So if you reg/rect is cold, then, either you are using all the power being developed, or you are riding in -56 deg weather or there's an issue with your charging circuit!
