I changed the oil and oil filter in my 07 yz450f yesterday. I didn't run it, so today i went out to check the oil level. I kicked it over about 10-15 times to get oil moving before i started, then let it run for about 2-3 minutes. When i checked it after about a minute after i shut it off, oil was coming out of the check hole when i pulled out the dipstick. It was somewhat foamy, bubbly looking. I have Yamalube 10w-50 semi-syn in it right now. It's not milky or anything, but I haven't had this happen before. I only ran it for a couple seconds after this, because i don't know what's going on. Please help!
