I have a issue with spark Plug current in my newly purchased hero glamour.i have complained this issue to Jaydeep hero show room and they already changed electronic parts and i have paid for this parts for 2-3 times but still i am facing this problem again and again.
I have shown this problem to representative at show room and requested to solve this problem without any payment as this is manufacturing fault.
