i recently got a dt and i decided to change the oil after doing this and running the bike i noticed the engine oil has gone milky white?

any ideas what this is...this is my first 125 2 stroke bike and to what i have read its something to do with water

what am i best to do? any checks i can do myself?

Water is getting into your engine...not sure where it could be coming from but thats deffinatly the problem..water in the engine.

put some new oil in it...go for a ride and check what colour it is after.

Gaskets are going to need replacing! Try a new head gasket first?

maybe somone else could give a bit more info for you aswell...

Check your water pump seal its probably that, change oil after finding problem and resolving it.

Thats normal mate, the circular spring is on the inside of the seal, it pulls the rubber against the impeller shaft, forming a water tight seal, just remember that when you install a new one it goes the right way in, take a pic with your phone cam

Take impeller out of seal, get some snipe nose pliers and carefully pull the seal out,from the middle, replace new seal, then build up impeller back up again, this pic may help

You will also need to put a bit of grease on the impeller shaft and oil seal lip when refitting.

Did you replace the gasket on the water pump housing, and also put both locating dowel pins back in?

Just replaced mine and it seems so far. Did you flush your cases out before putting fresh oil in? Mine was full of white slime in the bottom

 Hey there mate, it's not the water pump gasket seal... Its the pump retainers.. You'll have to change them, end then re-change the milked oil to new one!
