should be in fzs600 sorry - white deposit on oil plug inside surface

[shieldr]

Bike is pulling great but i recently opened the oil plug to find some white gunge that i have not seen before. I am concerned the head gasket is away. Any thoughts, checks or tips on this much appreciated.

There is not much in the way of back pressure ie any puffing out of the oil fill hole.
