Why is the oil overfilled after a dealer service?
Okay, I know I can do my own oil changes, but hell, I am no real mechanic and don't fancy doing all the things called for in the 5k service. So, I take it to a dealer. Damn crankcase is always overfilled. They try to explain that "it's hot" or "its cold", but no matter when I check it, it reads overfilled up to the last "L" in the word "Full" embossed on the stick. I figure it is about 10 ozs. over. Why do they do that?
I got myself a suction gun today. 12 bucks. Tired of arguing with dealers.

And how many times do you have the full 5k service done, just once I'm guessing.
Tired of arguing with dealers? only one way around that.
Plus you'll save at least $50 doing it your self..

Said it a zillion time but maybe you have not read it. Harleys are dry sump. Realizing that there is a few ounces in the bottom under the crank but unlike a car motor the oil pump is two stage. The return to the oil tank (scavenge side of the pump) is larger then the pump (pressure side) If you attached a 55 gal drum of oil to the oil tank it would not affect it as long as you left some space for the hot oil to expand to. If it's really too full what it would do would be push the dip stick out. 1/4" on stick will not matter. Hope this helps since I know I will get clobbered by the its going to blow oil out the breather but that is not what causes too much oil in the valve cover.
That being said I like you want it were it belongs and I run mine at the correct level when hot. You do need to check behind dealer but if I were you since you might as well be doing it your self if you fill the need to suction the excess out I would put a note on a tag at the oil fill of the bike saying 'Please fill the cold oil level 1/4" below the full mark for me, Thanks appreciate it.' and the mechanic will gladly do that. He probably fills he's doing you a favor by putting it a little too full knowing if you went the full mileage between changes you would be fine without ever checking it.

I could be wrong, but I don't think Dynas have been 'dry sump' for some years now. They have an oil pan and oil pump just like a Car from what I understand.
So yeah, being over-filled is a problem, one you don't want to play with.
If you decide to use a Turkey baster to remove it, fer chrissakes use a hose on the end so long that even if it does come off, it will be no trouble to fish out of the pan. Actually, so long it can't even fall into the pan.
