Recently changed oil in my pro 05 and its already gone milky think it was about 2 weeks ago...havnt been in water deep enough or not any water to get anywhere near the engine so i think its getting in when i wash the bike OR theres a bloody lot of condensation in there.

Any ideas whats gone i thought maybe one of the gaskets had gone ?? But im going to change the oil tonight wash bike first tho and then change and ride on sun see if it still goes milky again.

Almost certainly its the water pump seal leaking. Whilst your at it replace the shaft too.

If the problem's still there after changing the oil, it's possible that the water pump seal (on the impeller shaft) has failed. It happened on both my old Gasser and my last Beta. Very easy and cheap to fix and it's a good idea to change the shaft at the same time in case it's some imperfection on the shaft surface that's chewing the seal.

Yep wipped water pump off your both correct shaft and the seal have both gone well i think its just the rod hopefully i can get one tomorrow...cheers steve and blocky
