My '12 350 RR is is blowing oil out the crank case breather tube in a steady stream, possible culprits?
Thanks

Likely the rings are gone bud.
When the rings don't seal in the bore anymore you get excessive pressure in the crankcase and that blows the oil out of the breather.
Engine needs a rebuild.

So I have a bit more info, it only leaks out breather tube when on kickstand. Otherwise nothing.
