Chain adjustment on 4G from Bike Berry

I have been hearing noise, like clattering on the bike since I first started riding it. It did sound like a chain hitting something. I removed the cover on the left side of the motor which houses a chain driving the bike. I found a lot of "slop" in the chain. My question is: What king of adjustment, how much, and how do I adjust it?
The other two chains are adjusted properly and need no adjustment, and are not hitting anything.

Thank you for reading this;

Its a pocket bike gearbox that Bikeberry named a "5G" to make buyers think it was like a 4G gearbox.
There is no way to adjust the chain tension.
 
Thanks... I took another look at the transmission chain, and did find a master link. Has anyone removed a link from this chain? Is it easy to do? Removing the link from the 415 is simple, but I suppose removing the link from the transmission chain is a little tricky.......thanks for your input!

Yep, and it rates down there with the Stage III in my book.

The '5G' is for the short shaft clutch included 142F isn't it?
 
It is a double chain, and I'll post a pic a little later today. It is 5:30 am and I am not awake yet,,,,,,I really don't know if it is a long shaft or not. How do you tell the difference?

There are pics on this forum of one of those gearboxes modified with a spring loaded chain tensioner.

The Huasheng motor is a short tapered shaft.

Thank you very much for your answers to my problem. I have been riding everyday on the bike with this new motor, and all is quiet. No clattering like a loose chain. I did not adjust anything, put the cover back on, and everything is hunkey-dorey. Was the noise from just breaking in the motor? I have not heard any noise except the running motor. It looks like the chain is at it's proper length. I wonder what was making all that noise I was hearing. It really sounded like a clattering loose chain that need to be adjusted. But I was wrong. Thanks for reading this.
