Nasty gunk in air box?

I'm in the process of changing my spark plugs due to the bike running a little odd the last 2 days, and found a little pool of oil in the bottom left corner. Also some build up of gunk along the upper rear center of it. I'm gonna assume its commingle from the crank case breather at the back of the air ox, and that its on the left side from being on the kickstand. What causes this on these motors and how do I remedy it?

Maybe from over filling the oil by a little bit? I'm at the top of the slashed section with the bike level on the dipstick.

Here's a pic. Excuse the poor quality from my cell phone.

Re: Nasty gunk in air box?

Totally normal. The pcv vents into the air box as a way to increase ring sealing and somewhat reduce emissions. You can clean it all you want the oil will still come back. It is also a nice way to help collect dust that would ordinarily end up in the motor. Don't worry about it.

Are you screwing the dipstick in when you are checking the oil?

No. I was under the impression that you do it with bike flat and straight up, and dip stick not screwed in.

That's correct, it was a trick question
