CG125 Engine conversion to 250 Help

Hi

So I have been looking at buying a 230cc - 250cc engine that will bolt into my CG125T frame as a fun project. I was originally looking at an overbore kit but looking at research its a one way ticket to a melted engine.

Looking at multiple sources I found a couple of brands to look that being Loncin, Shineray and Zongshen. They all appear to have 250cc engines that follow the same design as the CG125 engine but I am uncertain if the dimensions line up. I'm aiming to have as simple time as possible changing over the engine so no mounting brackets/aligning the chain sprockets.

Basically what I'm trying to find is just an engine that will bolt directly in, hopefully has a bit of power behind it (well whatever a 250 can deliver) but also reliable, price isn't too much of an issue.

Any help is welcome.
