The older YZF's radiators were a tad small so they would overheat when sitting still. Even the newer ones will do this if sitting still for too long as there is no air flow across the radiators to dissapate the heat.

The overheating problem is more severe on the older bikes. The best bet is to make sure you avoid sitting still for too long. I know it's not much of a solution, but it's just the way it is with the older YZFs.
