The best result: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-0I5yk7howsY.html But they changed the cylinder to 80ccm. Changes between generations are probably too big (emission standards, etc.)
I used the following parts: -Malossi M4516332 -Malossi M5111597 -without ring -Malossi M5514396 Stock: 50ccm 4T cylinder, jet, camshaft, and many others.
It might be difficult. I-get 50 is another engine and new EURO emission standards. Try these sources: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-fJmxHLQtzNA.html Here is only 60km/h and ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-0I5yk7howsY.html but here is 80ccm.
