I changed my oil yesterday and came up with another reason to change it hot. I was taking a sample for oil analysis. You're supposed to heat it up and get the impurities evenly distributed throughout the oil, so as not to skew the results.
Rboe, the oil temp needs to get to about 170-180 degrees before the moisture in the crankcase will vaporize. I have the same issue in my plane in the winter (it's even colder at 10K ft.). I have a plate that blocks the plane's oil cooler in winter. I'd like to do the same with the CB, but as you pointed out, you really need a temp gauge to figure out when and how much to block it.
