    Haven't heard about this theory, but I've done that same as you, added more when it was low and voila, too much appeared.

    Decided that before tomorrow's oil change, after the final ride of the season, I'll park the bike first on the side stand for a while, before putting it on the centre stand to drain. Usually I just come in from a ride, park it on the centre stand and drain. This does not allow the oil flow out of the heads before starting the drain, and maybe trapping old oil inside, to produce too much oil later.

    Uh,
    wouldn't the oil change process be the same on the RT as it was on the RR you previously owned ? It's the same 1150 engine.

    He told me repeatedly, that the 1150 RT engine 'Hides Oil really well!

    Three times, before we signed papers, he repeated to me the above.

    So, upon adding my third quart, I realized that the new oil went right up to the top 'max' mark on the sight glass, and then thought... 'Oh sh*t', too much oil'.

    I drained the oil down about 3/4 quart through the bottom drain plug, and then
    let the glass settle.

    I added some oil about 1 cup at a time. Stopped, started the bike up, let it settle, and added only another cup, and visibly saw signs of the oil on the 'minimum' mark of the sight glass, and then, stopped there.

    Has anyone else heard this theory about the RT 'Hiding Oil Really Well' and forwarned about not adding 'too much oil', even though the owners' manual and other service manuals say 'fill to max level'?

    Oh no... I think I started yet a third thread off of this RT oil question.

    The way to check the true oil level:
    Engine must be hot, 5 bars showing on the RID, oil cooler hot
    Put on side stand and shut off.
    Wait 5 minutes (this will allow oil trapped in the oil cooler to drain into the sump)
    Put the bike on the center stand.
    Read the sight glass.

    The oil is "hidden" in the oil cooler, if the thermostat (on top of the engine) feeding the oil cooler input line is not open (at operating temperature) , it will not let the oil drain out of the cooler.
    If you look at the oil cooling circuit it makes sense.

    I have been checking my oil this way for the last 11 years and get consistent accurate results every time.

    Sounds like a good plan for me and will do this in the future.
