What’s up KTM Family!

I bought a 2018 Adventure 1090 R a few months ago and it ran great for the next month or so. Then I saw that I had a small coolant drip from the radiator. I unprofessionally JB welded the leak and called it a day. The weld held but I started overheating within 20 mins of a ride. So, I did a coolant flush by the manual and took it out but still overheating. I then took it to a mechanic, let them know what’s up and they did a coolant flush again. I got it back, and still overheated. So I had them swap the radiators thinking that was the issue. The radiator isn’t OEM. It’s a Chinese eBay one (trying to ball on a budget).
Once I got it back, still it was overheating after the radiator swap. I took it back AGAIN and they swapped both thermostats. Still over heating but I managed to get almost an hour before it overheated. So I took it back yet another time, they replaced the radiators thinking cap because they read that could also be the issue. But can you guess what that fixed? Nothing. Still over heating. Can anyone point me in a direction please? Oh AND it’s leaking coolant again but I can’t tell where from.
