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.

What do you mean?

It sounds like it's not getting enough fuel in the midrange, but that's sort of a guess.

Check for loose connections at carbs:

- rubber tubes fully pushed onto engine
- carbs fully pushed into rubber tubes
- hose clamps tight


One troubleshooting technique is to restore everything back to previous condition when things were working. Put the Kleenex back .

I restore everything with the old air filter and the bike still have that problem, the "klenex" i was meaning was a piece of bath paper, i don't know if maybe y move the hose that go from the air to the carb, because before open the air filter box the screw from down i can't remove because the frame block to remove the screw :/ I already move the "idle speed screw" and the bike is stil have that problem
