Interesting, thanks for the reply’s. I’ll keep an eye on it, and hopefully get it out for a longer ride soon.
You need to pull the valve covers and physically clean out the mayo and blow out the breather hoses.
I have an oil temp/pressure gauge on the car I do track days with. I was suprised at how long it took the oil to get to temp when I first started using it. I would have figured on the small oil value Guzzi it wouldHave gotten to temp much faster.I’ll keep checking it out. Had a lovely ride today, haven’t checked the box yet.
Is your track car air cooled? The challenge of air cooled motors, especially bikes, is to make sure they cool sufficiently in all conditions which can lead to overcooling in conditions they are used less often in.

Indeed, compare my 2 Ducatis for instance:
Effectively they are very similar engines, sharing the same bottom end and similar displacement but one being air cooled, the other water cooled. Not only does the water cooled engine run at a more consistent temperature it also warms up much quicker, especially noticeable as I have the same aftermarket digital dash on both which displays oil temperature and the air cooled takes an age even show a temperature (only displays when above 40c) whereas the water cooled hits 40c within a couple of minutes.
Also, in all but extremely hot conditions the air cooled runs a cooler oil temperature (generally by 10 - 20 degrees) but, in extreme heat will ultimately get hotter - though being in England that is rare...
Most of the mayo forms in the separator box at the headstock & along lines to airbox & sump. If there's a lot in the airbox, there will be even more at the bottom of the sump & in my experience hard riding & oil changes doesn't shift it....at least stuck at the sump bottom, it won't get back into the oil galleries.
Harleys are known to run hotter than Hades. However the Sportster I had was notorious for making vanilla milkshakes in the winter. In my opinion the best engine, short of the modern Revolutions, Harley ever built. It didn't run hot in hot weather either.kk
Another oil in airbox thread?!? Unfortunately yes. Slight twist.I have read through as many posts as I can find on the topic, and haven’t found one yet with the same issue.2016 V7ii North American Bike26k kms on the clock.Last year I changed several gaskets (including a head gasket) and all fluids. Bike ran fine, and sometimes ended up with some oil in the airbox. After I settled on 1.6 liters of oil in the sump, I didn’t get much in the air box at all.Stored the bike in the garage over winter. I changed the oil and filter so time over the winter, and then got the bike on the road in March.The creamy oil in the box has been happening every ride this year.Ambient temp has been below 20c (under 68 freedom units), and my initial though it’s it was just moisture build up in the bike and would go away. Next step is draining the oil to check volume and see if I can see any issues.But has anyone had the same? Anything I shouldBe looking for? Seems like this has to be water in the oil or bike mixing air and oil and frothing, I just don’t understand from where.
68 years ago I got my first car, a '56 VW. That winter I made a sump heater, a cardboard box that closely fit under the oil pan with ceramic bulb holder in it. The inside was lined with fiberglass board insulation. I used a 100 watt bulb. Since then I've used these on all my air cooled engines in cold weather.
Faffi, you left out a most important ingredient in your elixirs, Tabasco.
