My speedfight 2 is making a much louder noise now is it because my engine is damaged because my moped broke down the other day as well and my speed of my bike is now much slower

it could aslo be a main bearing breaking up and rumbling this will transfer the metal parts up through the transfer ports and damage the piston causing lower compession and less power and speed.does it make a metallic scoring noise while its running?and does it get louder with the revs increasing ?

you need to check your transmission, could be your clutch shoes broken
