Hi all, I was hoping for a little reasurrance about my winterization process - or maybe a good reason not to do what I planned. I keep the Streetglide in a heated room in my garage. I just had all three fluids replaced at 5,000 miles, and now have 6,600 miles on the clock. Spectro full synthetic in engine, Spectro in primary, and Spectro full sythetic in the trans. I got to thinking it did not make much sense to change the trans and primary for winterization, because I have only gone 1,600 miles on them, and they do not pick up the acids / contaminants that engine oil does. My plan was to change the engine oil with new Specto full sythetic, do all the other winterization stuff, and then hop on and ride come spring. Anybody see any reason to change the primary and trans oil? Thanks!
