TC bros is telling lies. You need to charge at about 14.1 to 14.2 volts. Any less than that, and your battery will never be fully charged. If it goes up to 14.5 volts that is OK too, but may create a need to add water more often. Some lads get away with charging at 13.8 or 13.9 volts, but the battery is only partially charged.
There's a thread about that.

First question, why did you buy a new regulator?

First question, why did you buy a new regulator?
Have you tested the rest of the charging components? Is it the right regulator for the brush block on the bike? There are two styles of brushes early and late. Early brush holders need to be modified (nylon screw mod) to work with most "new style" voltage regulators.
Pictures and the tested numbers. We aren't magicians, we have to see or be told what you have to help. Lets see the brush holder. What wiring diagram did you use?
I don't see numbers for your rotor Ohms or the stator ohms test. That TC bros reg "should not" need the the nylon brush mod. Electrical troubleshooting requires that you test and verify each component is working correctly. That's why I pointed you to the charging guide, do the tests and the weak component or wiring problem will show up. Report back with test results?
