If you've just pulled off the freeway on a hot day and you're confronted with a long light, desperately look for a way to keep moving. You have to weigh the heat of the engine with the aspect of the light. There are parts inside the engine that are much hotter than other parts of the engine they require cooling, oil or air to keep the rest of the engine from heating up. W/o the engine running, there is no oil cooling. W/o the bike rolling, there is no air cooling. A dead bike is a radiator w/o a fan, just plain hot. Now your cooler parts are taking the heat from the hotter parts, bbq legs anyone?
