I am new to this site, I bought my ttr250 in February and rode it for about a month before doing a full strip down to it. Before the strip it was leaking creamy oil from the crankcase breather hose connected to the rocker cover. I hoped that the cleaning and replacing of everything would help get rid of the problem as the oil in the engine is remaining clean and the breather hose isn't cracked or split. A fair amount of this creamy fluid is pouring out after every ride, maybe 50-100 ml. I really can't think what is causing it!
If anyone has had and fixed this problem before please help! :)
if it was water cooled i would say head gasket looks like it has drawn water in somewhere where change oil & filter couple of times run engine then recheck
That creamy snot is exactly the same as the stuff i get out of my breather. Think it's normal! I expect its an emulsion of a tiny bit of oil, maybe some filter oil and some moisture. I think its perfectly ok, certainly my bike is fine with it!
+1 Padowan Looks like a oil/water mix for sure. Assuming that the catch tube is not split or cracked I think you are getting a little water in you air box. I sometimes find it a bit tricky to get the air filter cover on square and the gasket in the little grove, maybe that's it? OR maybe you are going thru some deep water and it gets a little in thru the snorkel. If you don't have the snorkel, that's probably where it's getting in. I think you are fine.
Thanks for suggestions guys, I'm more worried about the quantity of fluid after every ride as opposed to it being creamy. I haven't had the pleasure of taking it off tarmac yet so not been riding through deep water.
Well, the only fluid that you're supposed to keep in the engine is the oil, if the bikes not consuming oil, then the snot must be comprised of mostly external components (ie moisture/water from outside) so i dont think you need to worry. If, however, your bike is consuming a lot of oil, then it might be related...
Mine does it most when i get water in the airbox i think a bit is drawn back into the seperator
just remember for air to come out the breather on its way in it contains moisture (humidity) once heated the moisture seperates and ends up in the breather
