Make sure your idle speed is up a bit to keep good oil pressure during the idling periods.

Next, a sump full of Rotella T-6 wouldn't be stressed by the mild overheating your engine may well have to endure (look for your pipe to go gold then blue as a sign this is happening).

You can cut your bike off and on, but running it just a little and starting it a lot can drain your battery down.

If your course is well equipped, they will have a big fan out in the yard to keep the aircooled bikes nice and cool.  

If not, ask if you can go last in the line up for each exercise and try to keep your bike "off" as much as you can to keep it from overheating.

Last summer I rode my '07 in a parade on a very hot (95 or more) summer day. The bike essentially idled the whole time, at least 45 minutes or more. As far as I could tell, the idle speed did not change, nor were there any other signs of overheating. The pipe did not discolor. There was no particularly noticeable breeze, either. Fuel was E-10; oil Shell Rotella "triple protection" 15W-40 conventional. Remember that while at those very low speeds there is little air cooling, but the engine is operating at idle power and isn't making an awful lot of heat. There will be some convective cooling by the simple fact that the hot air in contact with the engine will naturally rise and make way for cooler ambient air.
