Royal Enfield — classic 350 chain heating and rear wheel jamming

Hi,

This is dinesh from coimbatore. I am owning classic 350 bike (Tn 99 e 8668).in my bike chain gets so heated and back wheel is jamming. Also while applying back break, some weird sound is coming. For every 3000 kms once i will service my bike in showroom.

Now i am facing this issue in last two services and taken my bike to showroom for complaints. They are just cleaning back wheel break after that it works fine.

In another couple of days again the issue occurs.
