Hello there!

I recently purchased an ATM50-A1 and it is making a rattling noise when I am accelerating, specially when giving it about 3/4 throttle. I am still in the break in period. Have only driven it about 60 kms. I did try adjusting the valves when I first put it together, by following the youtube video uploaded by 49scoot, but I am not sure I did it right because it is my first time doing it.

First time riding a scooter. I think it is pretty quick?

I am attaching two youtube videos. Just click play. I already added the time in the URL.

Below is a video of someone with a Taotao Thunder. Around minute 8:07 you can hear the same noise when he starts accelerating. You can hear it throughout the video too and I am wondering if this is normal? Is it pinging from running lean? Is it a problem with valve clearance? Exhaust?

Below another video, this time from a Pony50 making the same noise around minute 4:01

I am looking forward to your replies. Please help. Thank you!

I already got a new one but I am still waiting for my jet kit to arrive. I am a bit worried that it may be running too lean.

Here's a clip of mine just revving at the beginning.

Hello! I think I can hear it at minute 18:35 but it's pretty faint, unlike the two scooters in the video I linked.

I will check the exhaust tonight. The problem is that he doesn't have any video of the noise.

Honestly, on my Taotao 150, my sisters Peace Sports 50, and her bf's Taotao 50, the exhausts are absolute crapshoots when it comes to noise. They rattle like a can of marbles. The engines are naturally kinda noisy too, but the exhausts rattle
