Using far too much fuel?

[Minchy]

Hi, I?ve bought a 2014 ec300 around 6 month ago and only just got round to setting the carb up as it wasn?t running right, I?ve gone back to total standard settings as it says in the manual. The bike is running great now apart from the fueling problem. The bike was doing around 55-60 miles on a full tank, however now I have gone back standard the bike only does 40 miles to totally empty now, just wondered what I can do to sort the fuel out?
