Picked up another trike today 200s for $50.00

[motoman011]

I picked up a 1984 Honda 200s for a local guy, it's basically all there but it did not come with an engine. Does anyone know where or if I can put a lifan or copy motor in it and if so who sells them. I've done some reading and I'm still not sure what type of mods are needed or if they are direct bolt in's. Any help with this would be great.

Thanks
