The carb is 26 or 27? Adjust carb IS depends the spark plug condition.
Tires -Which is the stock brand? Taiwanese brand are OKish

I'm pretty sure it's a cg125, though haojin has been copying yamahas, so it might be a Yamaha engine clone. It's obviously a different bore rather than a completely new engine. I'm assuming the bore will give me just a little more power, though maybe not a higher top speed.
