Whats Wrong?

Well i went riding at a friends track today. Did a few laps and then stopped to take a break. When i shut my R off it had a sound of boiling water up under the hood. Took my hood off and it was rather hot under there and my steering stem was really warm. Looked like drops of coolant were comin from behind the left plastic shroud. I filled it up with some coolant but it still does the same thing. My oil light never came on once today either. Any ideas?

is your fan on? are you riding fast with air coming through radiatior? is your radiatior clogged with mud?

check if the hoses are f***** or if they leak on the way to the motor , or like he said mud and stuff in th rad. if your fan turns on when it starts to heat up... look for leak on the rad!!!!!

Took off the plastic and washed my bike today. I figured out that it was leaking from boiling over and going out the over flow tube. Should i put new coolant in and see how it does?
