I am in the process of replacing the water pump seals on my '04 450R.
On the last ride I ended up with water in the tranny. Anyone else have a problem with this?

 

First time I have heard of that one I think. I monitor the dirt bike forums as well for things like this, and don't think I have heard of it before.

Did the oil emulsify? Was it so compromised that you might have done bearing damage or anything like that?

Don't think I did bearing damage. Hopefully not, but yeah, it was like a pink milkshake.
Doesn't take much moisture to do that, though.
I am replacing the clutch.

 

There is an inner and outer waterpump seal. sounds like the inner seal is bad. seen it happen many times. easy fix.

 

Yeah, I'm changing inner and outer seals.

I have done it, didn't know you didn't know. Change the bearings, I didn't first try. After buying the second 32$$$ seal the bearing was sticky. I figure I hurt the bearing pulling it, to change that kicker cover.

 

Didn't know your seals went bad. Just thought you broke the side case. I was able to tap the bearing out from the other side so I didn't put any pressure on the bearings themselves and I didn't even put a mark on the race. Bearing has no stick to it at all.
If they have a bearing in stock I'll get a new one but I don't have time to wait another week for it.
