I must admit I've not had a bike that froths so much in the oil window. I understand the logistics or an open engine taking longer to get to a temp that will boil off any condensation in the oil, as well as longer journeys. As all my bikes are ridden in all weathers I am now thinking of putting a plastic card infront of the oil cooler to help it get warmer earlier and reduce the froth. My own feeling is two zip ties at the top corners then probably velcro at the bottom so you can put it up or down depending on the temp. Has anyone else found another way to reduce white froth and keep the engine warm during winter running?
I assume that the oil cooler has no thermostat! I've never had another bike, other than my aircooled 900, which has produced that milky effect in the oil level window (or on dipstick etc). With car engines I've always regarded mayonnaise under the oil cap as a bad sign. I like to think that the oil is still sticking to all the surfaces and the water is trapped as little bubbles safely covered by oil too.
If I were getting the water oil froth in my engine then I would not ride it in the winter. It is just the worst thing that an engine can have. Everyone wants to buy the best oil and then the froth happens. Trouble is that froth in a bearing will give zero lubrication and let the surfaces wear themselves away at an alarming rate.
I used to always try and avoid short journeys on my SS in order to allow time for the engine to warm through. I also used to take the oil filler cap out after riding to allow any water vapour to escape. I always placed it on the tank filler so I couldn't ride off without it.
