    Hi,

    I read that the European and US carbs have different jet sizes.
    I'm talking about an XJ700. There is a Canadian sticker on the frame somewhere.

    It has US main fuel (107) and air (70) jets.
    But the pilot fuel (40) and air(225) jets are like the European XJ750.
    The US pilot system is in fact equiped with 36,5 and 210 jets.

    Is this normal or may any PO have made a mistake?

    US carbs are commonly jetted differently because of our more stringent EPA regs.
