Spewing oil out

[NateZ]

My 95 cr250 has tranny oil that is comming out of the case vent tube at the back of the motor. I don't know how fast it's comming out, but at the end of a ride, the back rim will have a nice sand/oil dusting on it. Is this normal? My yz doesn't do it. Anybody?

My best thought is that you are probably overfilling the gearbox.

If it's very little oil, then you probably have the case just a little too full. No big deal.

Well i dunno what alittle bit is. It's enough to cover the rear wheel, and throw alittle bit onto the bottom of the rear fender. I'll check how much oil is in there, but im pretty sure it is underfilled (i didn't put a full 750cc in last time by accident)

Could be a right main crank seal leak or a warer pump seal.
