Oil seeping out of air box

[2faston3]

Hello:

I just installed my J&M CB and with all the body work off I noticed some oil seepage coming from the lip where the top meets the bottom.

Any ideas what this is?

I seem to recall some discussion about it last winter, and the cause. But recall is a bit vague.

Can anyone help me?

Yep, it's blow-by from the breather. There is no real fix.

Lamont:

Is it caused by overfilling the oil?

Thanks
