Good to hear that it was minor and evidently similar to what I have experienced a few times.
In my case when it has happened, it was right after I changed the oil and normally shows after a few miles of fun riding. Usually if I got a little extra fun on the throttle.
Has said before, wiped it off and seldom had any more showing, maybe once had still a little bit shwoing during the next ride, but never after wiping it a second time.
Even when I fill up to the right amount, I think there may be just enough oil left from the previous fill, that it may get just enough of a n extra to puke it out when you get on it for a little bit of time.
Once again, great news that it is not anything major. Get out and enjoy the ride and be safe.
Keep the Irish Whiskey and driving seperate today if you may participate enough of the cheer that you are going to do some jogs and sing "When Irish Eyes Are Calling" later on (my plan for tonight)!!!!
