I am afraid that I only have a Haynes manual which does not describe the area that I am looking at on my daughters bike. It is the 1982 electric start version and there appears to be a breather tube running from a location under the transmission cover, adjacent to the starter motor to below and outside the cover, approx 6cm forward of the drain plug.. Firstly, what is the pipe (is it a breather for the transmission case) Secondly, what may be the reason for the transmission fluid constantly leaking from the pipe when the bike is shut down? - I am certain that the leak is from the pipe and no adjacent gaskets or seals.
