Hey /dbt/, retard here.

Did my first oil change on a cbr500ra. Service manual said 2.7L (3 quart) on a change. Put in 2.5L after draining figuring I'd top up a bit more if it needs it, but the sight glass is showing overfilled. (Idled for 3 minutes, using phone camera checking I'm on the bike upright)
Did notice a bit of smoke come out, figured it's a bit overfilled no big deal.
Checked my drain containers, ~2.4L was drained

Tried to siphon some out, didn't work, cracked the drain plug let ~300m drain. Stood upright and checked again, still overfilled.
Did it again another 300~500ml, still over the top line, now the oil light is blinking, still overfilled somehow
Cracked again still not above the sight line.

Oil is now obviously underfilled by like 1L, what the fuck am I doing wrong
