Hi all ... has anyone come across a left hand crank case cover, the one that covers the starter motor and the chain sprocket, where the gearshift markings are shown on the cover, just like the 400F has on it's cover. I was going through some spares today to see if I had enough to put together a spare engine and came across one. I am thinking that it may be from a 350F nearer the end of of the manufacture of them, seeing as the 400F came out with the markings ... cheers
