Should oil be coming out of my crankcase pressure releif hose after running in 4th-6th gear for awhile?

i have a 06 Yamaha Blaster and after i get done riding it in 4th-6th gear full throttle for a while i will stop to let it cool down, but when i do i notice that it has oil coming from the crankcase relief hose and i dont know if it is suposed to be doing that. i did try and plug it and the piging noise i have in the head went away but when i removed the hose i had a lot of pressure in the crank. so i was woundering if there is a way to keep the oil in the crankcase but let the air out.


OH YEA i just bought this bike 2 weeks ago and its my first 2 stroke so i dont know alot about 2 strokes.Should oil be coming out of my crankcase pressure releif hose after running in 4th-6th gear for awhile?

I've had that problem with some of my cars when I'm putting a thrashing on them. The ultimate solve would be to have a baffle under the outlet leading to the hose. Otherwise all you can do is reposition/lengthen the hose ,or add a small filter to the end to capture oil but let it breath.
