any ideas what could possibly lead to this, I was thinking of valve guide seals, bad rings or valve seats?

Hey, CRF450XNut!!!

What year is your 450? Is your crankcase breather routed back to the airbox? Would there be any chance that maybe you over-oiled your air filter (is the oil in the box the same color as your air filter oil?)?
