I know that a lot of people think that you just have to ride more to get rid of the moisture in the crankcase, but I just don't think that it gets hot enough in cold weather. I ride regularly in the 20's and lower....so this year I installed a Thermo-Bob and I'm glad I did. No more condensation on the sight glass when I get to work.
