I just changed my oil and filter, when I added the oil I stopped at the 8 oz mark on the first quart, and about half way thru the second quart I observed oil pour out of the neck from the bottom of the funnel. I checked the oil and observed it was right at the neck opening. has anybody experienced this? I am in the process of draining the oil now. and will add more oil. any suggestions or reason why this happened. I only had 2 quarts of 20/50 so I know I didn't use 3. I am going to use 10/40 because that is all I have left and is what I use on the other bikes.
