There is a black rubber tube which hangs under my Thruxton which is dripping what appears to be oil from it. Not all the time mind you, but once in a while I come out and see a very small oil stain in the driveway. What is this and should I be concerned?
Is it seeping out of your air box ?- they have a tube which drains oil from the box - but it is normally sealed at the end and you pull it off to drain every now and then. The large crank case breather tube from the motor dumps into your air box and this is what the other drain tube collects. If it has a hole or you have never drained it and oil is filling the bottom of your air box - the seepage may be from there. JCW
