FSE450 2005 crank case brether
 
Hello, I hope to get some information from knowledgeable users. crankshaft breathing tube makes strange noises "flushing toilet" when engine is turning, but not when running. And also leaks oin when in high revs. Is there problem with the piston rings?
the bike starts fine, runs great, no knocking noise, only the pressure in case :(

you can hear the sound when i turn engine and stop. in this video

There was a recall/modified breather tube when they were new. I don?t have the info on it anymore though. I would get a leak down test done to see the condition of the rings and go from there.
