06 Yz450f Breather Hose

On my 06 yz450f it Started blowing alot of oil out of the breather tube not a little like normal. In 2 hours of riding it blew out half a quart at least. Has anyone heard of this. The bike still has all the power as normal.

It sounds like its time for a new piston and rings.

Thats what I was thinking but theres no smoke.

Sounds like you overfilled it with oil. Did you recently add or change the oil?

I thought the same then i drained the remaianing oil there was hardley any left so it actually put out more than i thought
