Am Getting 28 KMPL

I have a brand new pulsar 135cc and at 552 KM, I refilled the full tank fuel in my bike; that was just after 1st service and after 760KM again refilled for full tank and required fuel was 7.32 Liters; So mileage is 760-552=208KM and 208/7.32= 28KM per liter ;; is it a normal thing to get such a low mileage for a new engine. Also when I fully refilled my tank 1st time, Petrol pump boy filled 8.45 Liters even there was some fuel in reserve and bike was also running properly so there was around one liter in tank that time … is it possible ??????? OR That's a trick played by pump boy????

Best Features: Speed is upto 108kmph
