I guess I thought it was understood that I meant the other stuff on top gets oil too. I don't agree about a few drops down the tube being wasted as long as some gets down and around the cam followers.
That area is probably the least lubricated area of a 4-stroke and thus I agree should get a dab of oil sometimes. My Enya 4-strokes have very tight cam follower (lifter) bores so the oil I drip down the tubes doesn't go very far very quickly. I'd assume Saito makes their engines with similar tolerance.
