    hello.I am new to this forum and have tried the search but still need help.
    My bike,1983 xj900,has the mikuni bs35 carbs and I need to replace the needle jets along with the air pilot.I have the number y-0 from the manual for the needle jets but that doesn't seem to corelate to numbers from any supplier.It seems that I need a series number.

    I appreciate all help.

    I wonder if these are oem from Yamaha?I tried Proflo and Motorcyclecarbs and both sites have extensive listings but nothing that match's that series #318.

    They have them,pricey but may be the only way.The more common ones available from the web stores are 1/3 the cost.

    Thanks for the help Rick.
