  • Honda CB Unicorn poor Mileage

    Hello Folks,
    I own a 2013 Honda CB Unicorn 150. Apparently, I am getting poor fuel economy nowadays ranging from 30-35KMPL(40 Tops).
    I have decarbonised the head, replaced the cylinder kit and valve stems around 200 KMS ago, bought new chain and sprocket(chose Hero Hunk/Xtreme's for better low end torque), replaced spark plugs, air filter, cleaned the carburettor and replaced vacuum piston.Yet, I'm getting really terrible fuel economy even though I ride only below 4K RPM or 40KM/h.
    Also, is there any way to obtain an Air filter box unit,cap and cover ? The bike makes strange grunting noise when I give throttle.

      You are getting lower fuel economy because of Carburettor tune it towards Lean mixture to get results. As carburettor setting is towards rich side which results in sending extra fuel. There might be few video regarding carburettor setting on You Tube.
