As Tamir noted - check the oil level immediately.

The CBR doesn't hold much oil, and you don't want to run it low. You can safely use Shell Rotella T5 10W-30 that can be purchased at most auto supply stores. Rotella is a diesel oil, and is safe for use in cycle engines. Do not use a standard auto oil.

Start by looking closely at the highest point where you see oil. Take a 1/4" dr socket (Probably 8mm) and check that any bolts in that area are snug. Don't overdue it - just make sure they are snug.

If you can't tell the origin f the leak, completely clean any signs of the oil, make sure the oil level is correct, and keep an eye on it. Extended high speed riding can blow the oil around and make it hard to find the leak.

From the photos, it seems like it may be coming from the area around what looks to be a crankcase breather, but it's hard to tell.

I appreciate it so much. I checked the oil level last night and even though it leaked all the way home the level was still ridiculously high. Should have noticed this before I even bought the bike. It covered the entire glass viewing window. I already had a oil change kit and a air filter on the way. From what I’ve read this caused the oil to push out of the crank breather. I’m out of town till Sunday but I’ll find out when I get back. Replacing the oil and putting the right amount should resolve this problem if that’s the cause correct.
I think you found the problem.

Be sure to install the oil filer in the proper direction - it will fit both ways. If it's installed backwards it will block oil circulation and toast the engine. It has happened numerous times, even by "qualified" Honda Techs when they first came out.

Be sure to check the air filter, and almost everything else you can think of, while you are at it.
