Peugeot speedfight 3 pops ang bangs problem

Hi so lately im having a problem with my speedfight 3, it shoots from exhaust like an automatic weapon. Problem started when I was heading back home from 10km trip engine wouldn't rev, only goes to about 50kmh. I found that there was a huge hole in the intake manifold and it was sucking air from there, so I replaced that but problem still wont dissapear.

I will leave a few videos for you to understand my problem better. And im waiting for ANY suggestions.
