Klr & cold weahter

Hello Everyone,
I have a question for those who do alot of cold weather riding, bought my2009 KLR in July 2010. It is now December, I'm still riding the KLR to work and back. I have noticed a milky film in the site glass and on the oil fill cap. I ride one way around 5 miles in morning temps in the single range, afternoon temps. 18-25F. To make a long question short ,Im hurting the KLR by operating it in such cold temps.? I do plan on changing the oil once a month,during cold weather operations . any pointers ? THANKS

its because the oil isn't getting hot enough to evaporate off the water that condenses in side the engine which then mixes with the oil and forms a milky emulsion. i asked a mechanic about it when i first noticed it on my old bike who said it wouldn't affect how the engine ran or damage it. it can happen in warm conditions to if you often ride for a shorter length of time than it takes for the engine to warm up. the thermo bob could be fix for it but am not sure. the oil in mine is still looking clean but i might try a thermo-bob if mine goes milky.

Yup. Won't hurt anything...although I might change to a different grade oil due to the cold. I don't know if a Thermo Bob would help or not, but I do think it is a valuable addition to the bike regardless.

But you should be fine regardless (take this with a grain of salt...the kind we never get on our roads cause it never gets below freezing). Can't trust a CA rider about the cold.

Just a thought.

Sounds like the oil, although I've only seen this happen to bikes which are exposed to lots of water. Either riding in heavy rain or doing many creek crossings / being droped in water. Water in the oil is a bad thing from all that I know, I'd change it and try a better brand of oil.

I think Rob-grout hit it. I get condensation from short runs. Running the bike for an hour at higher temps clears it up on mine. It ain't just a KLR thing. Everything I ride gets it when the temps get below freezing. The engine develops condensation. If we don't run them long enough, hot enough to burn the condensation off, we get a milky residue on things.

Engine oil has emulsifiers in it that is intended to trap moisture and that is what you are seeing. It shows up at the coolest part of the engine, like the oil filler cap. You should go to Minnesota and pull an oil cap off a car during the winter that never leaves the city limits. Looks like a milk shake.
If you change the oil you should reduce the problem temporarily. But moisture depositing will return unless you get the oil hot enough to really vaporize any water that may condense into the oil. The brand of oil will not change this reality.

I tend to allow all internal combustion engines to warm up before blast off, more so when it is cold out. I want to believe I find less condensation in the sight glass when I do this. YMMV.
