deepNdirt, I think you are on to something here...especially if using the shorter of the 2, will have you over filling the crankcase, and could explain why or if you might been seeing oil blowing out the vent tube,
I'm home in town so I can't look at my YM240, but I thought my metal-top oil dipstick was longer than Ginormous' photo.
Again, I suggest pour in four quarts of oil and see if that reads halfway up the oil dipstick. I think it is calibrated so 'full' = 4 liters, about 4.2 quarts.
Another variable: Is your dipstick on the left, or right? Early 2TR20 had the dipstick on the right. Maybe the mount point for that one is lower, so a shorter dipstick might have been used. Again, pour in 4 quarts to verify the dipstick.
