white cloud in my oil window

I saw an almost white milky substance in my oil window. Could this be condensation or is my head gasket blown? how long should i wait to see if it goes away? Its a brand new oil change.

The horrible answer is: It depends.

A little mist in the oil window and a tiny bit of "cream" in the filler cap isn't something to be overly concerned about. If you're removing your filler cap and can see your clutch plates covered in "cream", that's a definite concern. There could be a multitude of reasons for a little condensation making its way into your oil (even freshly changed).

When it comes to these things, I do it the 'old fashioned' way. I use my own senses. Does the engine make new or different noises? Is the power down? Does the clutch now slip more? If you're familiar with the bike, you should be able to notice these things if you give them your attention.

Clean the goop from the filler cap, and keep an eye on things. If the amount of white goop doesn't start to diminish (and/or the ass dyno is giving you concern), you want to check this out a lot more thoroughly.

The best advice I ever received was "Just look pretty and try not to break anything."

Likely condensation. Wouldn't worry about it too much. Especially if there was no coolant in your old oil.

To be safe you could change the oil again, look at it after idling the motor, take it out for a longish ride then come home and check it again. If the oil is still mixed with coolant then you have an issue.
