    Just remembered something i was meant to ask before in other post.

    How come there is oil leaking out of my number1 carb?

    No oil in the carb, so it has to be coming from somewhere else.

    The engine breather pipe from the head, on a 2KR hangs out the back and out below the gearbox, 3LN might go to the air box. Most modern bikes do and if you drop them, the oil from the head/valve gear can get into the airbox.

    Thats why i asked though cause i know there isnt meant to be oil where there was oil and this was before i crashed...
    But it was definatly oil and was definatly coming from my number1 carb.

    i know its not really important now but im curious as to how this was happening.
    it was like it for the two months before it got dropped same time everything else was failing.
