I have backfire in the carburator

Dear forum members,
I hope you can help me here.

2 months ago I bought a Yamaha Raptor 350cc from 2008. Everything went well until recently.
If I drive slowly in low revs then I get backfires in my carburetor and at that moment he also holds back. If I go through everything goes fine it's only during slow driving I have the worst in 2nd gear around 30km / h.

I then did these things myself:
Carburettor cleaned in an ultrasonic bath
New spark plug
Controls valves
Compression test

But unfortunately nothing helped, so I brought him to "De Liége Quads". They have cleaned the carburetor again and cleaned a new spark plug and air filter. At first the problem seemed a little better, but it soon became apparent that it is still the same.

Does anyone here have an idea what it could be? I am slowly starting to turn gray.

thanks in advance
Mvg Fabian

I am having the same issue on my 2005 350. Does it only happen while the bike is warming up such as if you try driving it prematurely? I think my issue only occurs during warm up but I may just not notice it due to not riding at low RPM much once warmed. I notice it almost sounds like a Hiccup, does that sound like what you are experiencing? I hope someone is able to shed some light on this issue for you so maybe I can get some tips as well.
