250-500cc Grey/Beige gearbox oil

Hello my friends! I was changing gearbox oil on my WR 300 today and the oil was light grey/beige. I can´t see anything wrong. The coolant water looks fine and the water level is just under the cooling cells in the radiator. I filled up and almost nothing got in. Engine runs fine and clutch and everything is working perfect. Do you think it just could be condensation, or could it be cooling water that is coming in? Can coolingwater come in to the gearbox? I haven´t checked in the engine manual how it´s constructed yet.

Coolant can enter through water pump seal.

Ok. Is this a common problem on such a new bike? Around 70 hours on it now.

Not sure if that model has a crank case breather .. but if it does it could have taken in water tru it and into the trans case(water crossings and such.. but like Norm posted the Norm(pun intended) is thru the impeller seal.

Worst case drop the trans juice fill her up with some new fluid and see what happens after a ride..

Ok, thanks! I changed the oil and took a short ride down the street, and the oil looks perfect, but we will see after a real woods ride. And yes, there is a crankcase breather hose.

If there is water in the oil it will look like a milkshake or a frothy mud.

My spectro gear lube comes out grey with aluminum particles from the clutch.
