When I took the Motorcycle Training Course the class emphasized the importance of the "Pre-Ride Inspection" of your bike that should happen every time you ride. I propose the following ammended Pre-Ride Inspection modified for those of us who have curious boys:
1. Find your key, hopefully it was hidden the night before out of reach
2. Check your backpack to make sure that all the zippers are closed
3. Check the tailpipes and remove any screwdrivers that you may find placed inside
4. Look ontop of the motor for items that may have been placed there (eye level for a 2 year old)
5. Look for sticks placed between the spokes
