weird noise in 4k rpm

I changed the air filter to the motorcycle, when I opened the air box in the snorkel I had a kleenex, I took it off and cleaned it with compressed air, I installed the new air filter to the motorcycle, when I turn on the motorcycle start without problems, at the time of leaving, the motorcycle at 4000 - 4500 revolutions does not pass until it opens 3/4 the accelerator feels a "boost" and passes the revolutions again, yesterday i let it 5 minutes warm up, i accelerate the motorcycle and it was strange sound from the exhaust, as if it lacked gasoline or had a lot of air, here I attached video to tell me what could be, if I need to open more the carburetor or if you need something else, i put the old air filter and the bike still got that problem.
