Sorry I forgot to address some of your points, the followings:
Now I'm a little confused as I do know this scooter has dual radiators but duel thermostats? Can you show pictures of where you removed the hose housings from that do both clearly look like thermostat hose caps?
=>Sorry, my bad, it actually has only one thermostat and one thermostat housing. I was actually talking about the radiators temp sending units (not the thermostat).
Also where you are going to tie in the main hose from the water pump it looks like it's going to be a pretty sharp bend on the hose? You may need to soldier on another 90 degree elbow fitting with a short piece of copper pipe going to the back toward the hose to put the hose on to keep it nice and straight and in no danger of kinking?
=>That is a good point, I was really concerned about it. The original hose was a semi-rigid cooling hose and had a shape that was slightly bent to along with way it was routed. So I was trying to figure out a way to make the hose semi-rigid as well. But it certainly could be done with copper too. I will look into it closer, but I managed to increase the distance then decreasing the angle of curvature of the hose, but it still is slightly bent (but acceptable I guess)
The arrangement of the radiators does not seem to be an ideal in such bike. In analogy to an electrical circuit it seems that the radiators are in parallel. Maybe they should be arranged in series. The advantage of the parallel arrangement is that if one radiator gets clogged there is still another path through which the coolant can circulate.

The copper pipe will last forever and is a great idea not expensive easy to make like you need and will add to the cooling capability of this scooter.
Are there fans on both radiators for cooling? I know this scooter was built on a 250 engine in a 150 body so to speak but there is no reason why all the little things can't be worked out to make it a fun and reliable scooter.
I'll be gone today to church and then school clothes shopping for the grandkids but this evening I'll check back in for an update.
So glad you shared this and hang in there we'll get them going.
Again Welcome to the forum!

First of all Welcome to the forum TK and yes the copper tubing will actually displace more heat and yes you do indeed need the thermostats to make the system function properly:
