Hi all, I took bajaj pulsar in sept2012. It gave mileage 45 km per litre after 1st service it went to 47km and then after 2nd service mileage is not consistent when I check reserve to reserve with one litre once it gave only 40 once it gave 47 all the time I ride with in 40 to 45 speed only. Why this is happening . Kindly advice me
