Let Your engine warm to almost normal operating temp before heading out...also cuts down on unwanted internal engine condensation, and on some Trikes, easier on the Trans
I've always felt letting your engine 'warm-up' (slop the oil around) for 30 seconds even in warm weather is a good idea. But your engine will generate less condensate the sooner it reaches normal operating temperature rather than just letting it idle. Riding easily for the first several miles is the best way to accomplish this. A "loaded" engine warms up faster than one idling or "no load".
What is "normal operating temperature"? Is it different for every bike? The answer to that question is "No". When I worked at the refinery I had access to lube oil engineers and they all agreed on this: That it takes at least 160 degrees F oil temperature to just START dehydrating your oil. Any termperature lower than that and you're accumulating moisture in your oil. But it takes keeping your oil at 160 degrees, or more, long enough to get completely dehydrated. That's why you may have heard "short trips are hard on a car" (or any internal combustion engine for that matter). Personally, I limit my engine load to 1/2 of redline for those first several miles.
