I use the same bike and i luv it ,it gives me the feel of a Harley. It's been 3 months with it but i didn't face such issues. Maybe urs was a defective piece,if i was in ur place i would ask for a new piece.
This it the most pathetic bike one can have, better than this spend 90k more and get an Interceptor!! shit bike, even i have faced this issue at the 8th day of buying brand new yezdi !!
