Due to the inability to afford proper winter storage for my bike (1980 GS 400), and my wish to have access to it on any day that's fit for riding, it spends its winters the same place it spends its summers - in the driveway. Until a year or two ago, I've been able to ride it at least once or twice a month, year-round (Cold isn't a problem - my record's 13 below centigrade. The deciding factor is whether there's any salt on the roads), but in the last few years, the typical Nova Scotia weather habit of following a snowfall with a few warm days and some rain isn't holding, and it's starting to look like it could be mid-June before our current accumulation of snow is gone.
So, not wanting to have the engine completely motionless for a month or more at a time, the obvious solution is to occasionally run it for a while in the driveway - but, running an air-cooled engine without MOVING an air-cooled engine isn't generally the best thing for it. So the question is, does anyone have an opinion as to how long I could safely run said air-cooled engine in, let's say, 0 to 10 below Centigrade temperatures? - and would that be long enough to do more good than harm (or would a short run only suceed in generating condensation inside my exhausts)?
Appreciating any input and waiting for spring...
