Oil in airbox on an 07TTR 50.

I just took off the airbox cover to clean the filter and found an abundant amount of oil in the airbox. What would cause this?

Hi its cause you have too much oil in your engine... Just make sure tour at the mark and should be good

Most likely the crankcase vent is connected to your airbox. That was the first thing I removed on my xr50. Point the vent tube towards the ground like every other bike ever made.

I put in the specified amount and its showing perfect on the dipstick.

Start it up and run it and if there is more oil in there then drain like half of it.
