路WHAT???? Probably empty oil tank 馃槈.
British bike has a bad reputation for leaking oil, off course the tolerances where different back then, but many hobby mechanics must take much of the blame. (cough me included cough)
My RD200's crankcase split this way too and that leaked.
And the alloy of the Japanese engines were a lot softer than the British ones.
