So i was riding around today in a gravel pit on my 03 450, i passed one of my tracks and it looked really shinny in the sun. I figured that i was over heating because i was going kinda slow so i stoped to see if any coolant was coming out of the over flow tube and sure enough the frame drain bolt at the bottom where the frame splits into two is gone; oil is all down my engine and all over the lower part of my bike. I must have rode for maby 5 minutes like that. when i got picked up in my buddies truck i drained what was left in the crankcase to see if i had any oil left, there was maby 1/4 cup oil in there. So what my question is how screwed am I. You read about things like this and you never expect it to happen to you.
