    Main air jets and what they do?

    Is yours 140s?
  17. V

    Main air jets and what they do?

    Yes that is the sizes I bought. Lets say the stock size is 160 cause that is what the carbs had in and I change them to 180s. Will the bike run fine?

    Main air jets and what they do?

    I bought new jets cause the old ones were the wrong sizes. Mains were 115 , pilots were 45 with stock airbox and exhaust

    Main air jets and what they do?

    Larger one 8 o'clock. So 180 will be fine if the stock size is 160(1.6)?
