One of my friend got RTR 160 carb... and he is not getting a mileage above 35... once its mileage dropped to even 20.. and it has never gone above 40.. and even when he runs normally for like in 1 liter without revving the bike more than 5 rpm still not getting above 40 mileage.. I guess he should be getting a mileage of 50-55 as per everyone says... what can be the problem...
One thing: The bike pickup is too high more than 180's..
