Yeah. i just changed my transmission fluid on my 85 lt250r. I unscrewed the bolt underneath the motor. The fluid that came out was milky green.(real milky green). I crossed some deep streams, on my last ride(water about too my lower radiator). IM not sure if my radiator fluid is getting into my transmission or it's just the water from the streams. Im pretty sure my radiator fluid is not leaking . Because the fluid in my radiator was recently flushed and checked to be fillled. So ...............get be back guys thanks..

i dont have clue what color streams could make your oil green i woulda thought antifreeze like you. u had your vent tube up under your seat right? thats wierd have you put new oil in and ran it ,then dropped your oil again?

 

I know on alot of my dirt bikes I have owned when they had milky white oil draned from them the little seal behind the radiator pump fan was leaking and a new seal fixed it.I had mine mixed half and half though.Duno if it would be green if it was straight antifreeze in your radiator though.
Maybe you sucked up some swamp juice hehe...

 

just condensation will make your oil do this, does it sit in a sweaty garage? if it persists to turning whitish green again fix it because you will wreck it with lack of lube.
