    Hey guys, the time has come to refit the fuel pipes but I would like a little guidance. The three T pieces at the back of the Carbs need to be routed to the tank. Where do the two pipes that run on the same plane/gallery go? and I presume the single T piece at the bottom in the middle is the primary line from the tank?
    The parts ident doesn't give me enough to go on.
    Cheers in advance
    Curt

    Red line = fuel in
    and I'm pretty sure #58 is the transfer line

    The GJ73A carbs are different to that diagram. The lower T piece goes to the fuel tap, the two T pieces on the upper 'rail' are simply vent tubes. Stock they connect to two hoses that loop around the airbox and secure by clamps around the top of the air filter. As this bike doesn't have a pressurised airbox I don't see how they serves any purpose so I just removed the hoses and the clips (weight reduction)!

    Thanks for the replies on this. I was pretty sure they were vent hoses off the over fill tube in the float bowls but wanted to make sure. I now know how to proceed with the air box and pipes.
    Cheers guys :)
