Whining sound

No, it's not the gas tank one.

Hi, guys, I can hear a strange whining kind of noise when I am accelerating on my ninja 250r. Doesn't happen when I am idle or revving, only when im actually moving. And it increases and decreases with engine rpm. And it doesn't stop or fade away unless I'm moving real slow.

Kinda like in this vid at around 0:39 sec https://www.youtube.com/watch?v=WQU4TT--DqE

It's pretty loud and I almost don't hear the actual sound the bike should be making. I've seen videos on which the 250rs don't make that sound, so I'm sure it's not something normal.

I also found a thread about it, but noone actually said anything but "it's normal". So is it actually normal or?

btw, My bike is fully stock (if it matters, I changed the oil with a Castrol 4T Racing 10w40 and the oil filter) and I am a very new rider, so I am not too familiar with how stuff should sound.
