I started to hear a funny sound from my moped ('00 Kinetic Magnum)--near the variator. Well, I was stupid enough to ignore it until it broke down on my way to work. But I wasn't too far from home and was able to pedal it home.
I checked it out and it turns out that one half of the pulley (not the half that is the back part of the variator) somehow got caught in the metal casing over the flywheel and it broke. Naturally, Cosmo does not have that particular part in stock, but will be sending it as soon as possible.
Here is my advice:
Listen to your moped. If anything sounds out of the ordinary, CHECK IT OUT RIGHT AWAY.
I learned this the hard way, and have been without my wheels for almost 2 months.
Woe is me. )-:
