Thick oil just above the gear linkage on the side of the engine. There is 1 screw/bolt that seems particularly oiled up. Cheers guys.
I'd work on the principle if oil is coming out from somewhere it isn't designed to, then something's wrong and worth worrying about until it's investigated and sorted. That even applies to my 1968 race bike.
I agree about chain lube . I run a white wax chain lube and can see in on the bolt in exactly the same place .
