    Hi All

    well I have nearly finished the service on my 1999 610SM and it now starts and runs great.
    I have however come across a wierd problem with my fuel line plumbing!
    As anyone will know who is familiar with this bike I it has two main fuel lines from the left AND right hand side of the fuel tank into the carb.
    I thought I had put all the breather pipes back onto carb properly (and in the right place) but strangely have fuel pouring out of two of them (but only when I turn on the fuel feed that carrys fuel from the left side of the tank.
    The main leak is from a narrow black line which comes out of carb near the enrichener mechanism (left hand side of carb towards the rear of the unit).
    I think there is fuel also coming out of one of the thicker breather pipes hanging down through frame.
    As I say this is only when I turn the left hand fuel tap on.
    What have I done, PLEASE HELP ME!!
    Thanks in advance

    Whenever I hear of an FCR carb pouring out the gas it's almost always a stuck float bowl. In your case though a picture might be worth 1000 words to be sure your lines are all hooked up right. Are you sure the left petcock line is hooked into the right side petcock, as it should be? This would be hard to do, but it sounds like your left fuel line is routed directly to one of your carb vent openings. Also just to be sure, when you say left you mean, as you sit on the bike...correct?
