Honda/Unicorn
Engine heat Problem

Hi,

I have Honda Unicorn, which I brought from Fortune Motors, Hyderabad on July. Recently (2months back) I am facing problem with Engine. when I ride 3 to 4 km the Engine was getting very heat. I asked for Showroom Engineer regarding this problem. He said he want to observe for one day. I given my bike to Honda Show room @ Fortune Honda Showroom, Nereedmet, Hyderabad for service. after that service also I am facing same problem. How can I fix this problem. And also when i give to service, millage is also getting reducing. Now I am getting 47/lt. my doubt was "normally for how many kilometers ride the engine will get heated? "
