As shown in the video the bike has a slight bog/lag on low end or when blipping. My thoughts are the fuel pump is sounding off, took it to my local shop and they charged me 100$ said it was the air filter needing more oil creating a lean condition. Get the bike back and it’s doing the exact same as before. Anyone know the fix or have similar issues?

Kinda hard to hear in the video but it’s almost louder than the engine when riding in upright position. Haven’t had a wr250r for a while so I thought I’d ask if it’s normal.
