I used 2 engines from the scrap yard, to combine them into 1 engine, 2 stroke, 100cc 

I used a part of a 4-stroke engine and a part of a 2-stroke engine to combine into 1 engine, with a capacity of up to 100c, I tried operating it, and could reach speeds of up to 95kmh, everything works very well, thank you for watching the video.
