13 volts ac at idle goes up to 16ish when rpms increase

Wow. Something is not right. If the stator is actually "good", I would now expect the fins of the regulator to be getting pretty warm or hot. Do you notice any heating of the cooling fins on the regulator when the engine is running around 1500 RPM?
It should happen pretty quick. In less than 30 seconds the fins of the regulator should get warm with the engine running at 1500 RPM.

is 12 volts ac good numbers from stator?

No, terrible numbers.. If the voltage across the stator was low, the fins should get very hot. That's not what you have. You have no heat (no current output of stator) along with low voltage.

It is now pointing to a bad stator.
You can load test the stator independently of the bike using high wattage projection lamps or a cheap old 2 slice toaster if you have one laying around.
 
Well it won't make toast because your only putting out 60 volts but it should get warm. Better yet,,, use an old 1000 watt hair dryer. It won't blow like it does when you plug it in a wall, but it should blow like it's on "low" when it is really set for "high".

With the hair dryer set on high, it is expecting to see 120 AC. So if your stator puts out 60 volts at 3000 RPM, the hair dryer will just blow like it's on "low".
The fan should blow and you you should feels plenty of heat coming out of the hair dryer at 3000 RPM.
 
Would you be able to measure the AC voltage across the stator while the hair dryer is blowing at 3000 RPM?

This is a good amount of current draw (if you used a 1000 watt dryer or more) and just about proves that your stator is good. What I am looking for is about 60 volts (3000 RPM) at the stator with a good amount of hot air coming out of the dryer with dryer in high position.
