Hi,
I bought a Keeway superlight 125cc a few days ago and the seller never said anything about the 3rd gear being noisy or having issues!
Cut the story short, I went to take the bike for the MOT this morning and I heard a horrible noise in the 3rd gear.
it sounded like the chain was gonna come off!
I turned around and cancelled the MOT.
I've put the bike on the center stand and started it and put it in the different gears to see whats going on and where the noise was coming from and I found out that the noise is from somewhere near the small sprocket close to the engine!
This noise gets much louder if im moving the bike but it is still very noticeable even when the bike's stationary and it only happens in the 3rd gear.
Please view the video attached:

The bike doesnt slip out of the gears so this can't be a clutch...
what is the the issue here? and what are my options?
Thanks in advance.
