Had to refill, burning oil? Normal?

Bah, I didn't see the bumps on the right side when changing the oil the first time. I topped up to the top of the sight glass. Hopefully it was not too much and that it didn't damage anything.

Filling to the top of the glass is what I do.
There's a lot of space in there, you'd need to put many litres excess oil in before risking damage to anything.
