Normal
What about the air screw?A few weeks ago I also suffered a massive oil leak. I'd changed the oil and filter, but the filter cover lip had gotten a little bent and started losing oil. I ended up losing ~75% of my oil. Thankfully I caught it before it seized.Not all bikes have a sight glass, but if it does have one, it'd probably be by your right leg (Clutch cover).If it's too full (and your breather hose is plugged) it can blow out a seal, otherwise it should just come out of the breather hose.
