I have noticed a recent post about this model and have a question.
Mine was probably made in '35 as it has exposed valve springs and no oil feed to the rockers or valves. Plenty of grease nipples attend to the needs of the top end, except for the exhaust valve, which always seemed a bit mean to me.
I rode it quite a lot in the late sixties and early seventies and am now giving it a make over. Running dry never seemrd to bother the valve and guide, and the explanation at the time was that the lead in the petrol did the necessary. I was a bit doubtful about that as I don't suppose tetra ethyl lead was present pre-war and is now long gone anyway.
The question is "would the addition of a little 2-stroke oil (or some other substance) make life a little more pleasant for the valve and guide?" or did the manufacturer know best?
