2020 TaoTao 250 Engine Swap 87 Honda? Idiot Question?

[Systematic]

Want to throw a different motor in the 2020 tt 250. I am quite literally the definition of most ignorant beginner compared to this community. I’ve done a butt ton of research and can’t tell if this is possible or if my motor in particular if a ridiculous notion. I digress, I have a 87 honda xr250r motor that’s more than quick enough for me. If I were to cut half me hp with this stock TT motor it would destroy me, even though i would have the satisfaction of having the first brand new thing I’ve ever owned I love the body and style and all such and things of the TT 250. But I would be psyched if I could put the power of my Honda in the new bike. Can’t help but think know matter if I managed to do it, I would have to replace nearly everything else for it to work. I’m aware of the first day changes you should make to the TaoTao, like loctiteing and different carb to adjust idle and such, cleaning everything up really to ensure longevity. Please tell me if I’m ignorant or if this is at all possible. I just want to know my feelings won’t be hurt! Wanted to see if forum would respond before I asked a friend whos small engine tech, avoid embarrassment and ask the source in case he thinks he could, gets me super excited, to find out it can’t happen. I’d rather be chastised by the Internet than my friends, brrrruuuutal bunch I guys I know. Please help me out.
