Comolene from shipping, or oil leak - how to tell...?

[ArizonaKev]

Hello all. I have been noticing some brown leakage (alright, no smart comments now! Lol) happening around the left side exhaust pipe, where it goes into the cylinder head. I was thinking it was an oil leak, like maybe the cylinder head (cam) cover. But then I have seen on here where some folks mention this 'comolene' residue that is leftover from shipping.

My question is - how long after having a bike (how many miles) can one safely assume that it's most likely not that stuff, but indeed an oil leak? Is there some easy way to tell the difference between the 2?

If I hadn't read about that stuff, I would simply figure it's a cylinder head cover leak. But before I go to working on that, I would like rule out the comolene thing first.

Thanks all, and happy riding :2tup:
