Address:	560076

As displayed / said by company TVS Jupiter scooter is not giving mileage. Its clearly mentioned as 61 kmpl. As a consumer i'm expecting at least 50 kmpl. I bought my scooter last year and I have taken free service 5 times(each service paid 500 rupees). After first service mileage problem started. When i gave my bike for 5th service mileage was 32 to 35 kmpl. Service done by Indian motors, Madiwala. Service was very poor. I told service center people about mileage problem, they changed air filter even after that problem not solved. I need solution for this problem, Please help me.
