I have a CRF450 and today i changed my transmission oil, its been aboot 10 hours on the bike since i did it last usally i only wait 5 hours, and it was milkey. I thought it was maybe a blown head gasket and radiator fluid got it... but thats not the case, the coolent was fulll.... any ideas would b nice... thanks

Mine did that when the water pump seals went bad. Just a few drops of coolant will turn the oil milky and the radiator will still be full. Is there coolant coming out of the weep hole?

Could it have gotten in while pressure washing? or have you hit up any wet races? Doesnt take alot of water in there to send it milky

If it was the water pump seals, wouldnt my radiator fluid be going down?

I've had the exact same thing happen, coolant wasnt dropping, no oil in coolant or anything like that. I changed the oil, went for a ride, then changed it again, oil was clean this time, and no problems since. I put it down to a muddy race i did and pressure washing the bike 5 times in a day, like i sed, it doesnt take alot of water to get in for it to go milky.

If your coolants not dropping, and you've got no oil in the coolant, i'd change it out, ride it, then check it again, if it's milky again then investigate.
