2009 250 ninja foggy oil indicator window.

Hi all i recently changed my oil and filter and noticed on my oil indicator window is fogging up oil still looks clear from after i ride it. Today i took it for about a 14km ride and i noticed after it cooled it fogged back up. I checked the coolent and thats still full to the top. I do notice tho that my exaust drips water every time i start it. Can anyone help me with a daiegnosis?

Cheers

Try opening the fill cap after riding. There is humidity in the engine. Likely will not cause any issues but sometimes happens in hot/humid areas.

Where are you located?

Water (exhaust drip) is a by product of internal combustion engines. Why do you think pipes and mufflers rust out? Don't worry about the water drip.

If your fuel tank petcock gasket (rubber) leaks (gas on the ground or garage floor from an overflowing float bowl), then gas can get into the oil. This will cause the cloudy oil level window and raise the level also.

That's all normal. Ride longer to help remove the moisture, but depending on conditions it may happen more or less.

It takes time and heat to evaporate moisture from the engine, oil, and exhaust system - but it's always going to be present to some extent.

Ride to a NASA research center, put the entire bike in their huge vacuum chamber, and the water will boil out of your oil. Problem solved.

Ride it longer, get it hot, see if the issue still exists

If you frequently ride only short distances, you may want to consider a Thermo-Bob. It'll help your engine get up to proper temps more quickly. https://www.ninjette.org/forums/showthread.php?t=88799
