Hello all,

After 110km my new ( 1 month ) tsdz2 motor started making a noise even without being turned on.

Does anyone had this kind of noise before?
Any help would be appreciated.

thank you very much!
Regards,
Filipe
 
Update : If I rotate backwards it does not make any noise, only when I rotate forward, and it makes noise even without power nor chain. According to this video

It might be this gear. Does anyone know it is controlled by the blue gear bearing ?
