symptoms of a worn belt

[coachhejl]

My scooter (vento triton minarelli 49cc) seems to be operating different at higher rpms now. As in its not transferring the power to more speed. It still gets up in the rpm range.

Im assuming it may be belt slip...or something went wrong with a roller or variator.

Inspection is always how I find CVT issues.

The first symptom of a worn belt is typically increased RPM. It may happen gradually and be tough to notice for a while unless you pay attention to your tach regularly.
