I typically ride through the winter, when possible, and this fall has been typically cool and damp, so moisture getting in places I don't want it is expected. The other day I noticed a significant buildup of foamy yellowish- white crap on the oil level window. I did a quick oil change (didn't change the filter), using some Suzuki motorcycle oil I had leftover. Then I rode around for an hour, and saw that the gunk had burned off. So I figured the problem was solved. But today I rode to work, which is about 15 miles of mostly freeway, and when I inspected the window after parking, I noticed a bit of gunk beginning to accumulate there again.
I'm in the Seattle area. It's been around 50 degrees F, with a lot of rain or plain old dampness. The bike is kept in my garage at home, and sits under a carport sort of thing when I'm at work.
So what I'm seeing IS water in the oil, right? What can I do to make it more permanently go away? My understanding is that it can eventually damage bearings, etc. Should I be worried about a leak anywhere? Several months ago I was riding in the rain, and noticed some steam (I'm pretty sure it was steam, and not smoke), coming off the radiator. But I was never able to pinpoint it or reproduce it, so I ignored it.
Any good solutions out there?
