engine or tranny oil in air boot?

Have a 09 crf450r and when we pull off the air filter the inside of the air boot is soaked with the oil we are putting in the engine and tranny ? ( we know its that oil cause its the lime green motul 300v in the boot) any one have an idea of what would cause this to happen?

its from the overflow at the top of your valve cover its goes to your airboot mostly it happens when the bike is dropped and its over 90 degrees

^^^^ WHAT HE SAID... :thumbsup::thumbsup:

or when the crank seal is bad. Newer bikes or low hours you would be less likely to see this issue, and you would see a rise in the engine side oil and a drop in trans side oil level (oil migration)..
