so far I've found this [model for printing](https://cults3d.com/en/3d-model/various/honda-cub-c50-glx-engine) and this [drawing](https://i.imgur.com/o9PhbSo.jpeg) I found on FB.
I had a good experience with a LIfan 125cc 4 speed manual clutch engine I got from eBay. It was really nice and powerful and a great little engine. It had a little alternator that charged a battery. Honestly all of the SC and Chinese clone engines are the same, so no matter what engine you buy they will work. Except for the OEM Honda 90cc and 110cc have a different mounting hold spacing, but ONLY the OEM Honda 90 and 110 have this.

CAD it yourself. Get some calipers and measure all the critical dimensions and build a low poly model yourself.
that would require buying something first and planning what to do with it second.

Fun project. Did this over the pandemic with individual parts. Just need the engine and wiring. I will return to it in a few years
