This is what my CVT looked like when my OEM belt exploded at 80 MPH:
You can see the rear and center vents were full of white fluffy "cotton". I don't know if the Kymco brand belt is kevlar or not.
The largest piece I found inside the cover was a section with FOUR teeth. The rubber from the belt left little rubber marks on EVERYTHING!
Look at this outside pulley on the variator. It is in the process of being cleaned.
