Some drivability issues result from non vented gas caps. Some sort of vapor lock. It seems easy to tell if yours is vented and if not how to vent it, but what about locking caps? How can you tell if they are?

They used to be marked, but who knows anymore. Read the packaging if possible.
The 'vapor lock' is nothing more than vacuum in the tank the pump or gravity can't overcome resulting in no fuel to the carb.
If your engine has a carbon canister for vapor recovery the cap is probably not vented. My new scoot had an open vent line just asking for water to enter. I need put a line on that hose connection and see if I can pull a vacuum on the tank with the outlet line pinched off or plugged. If the cap is vented I should get no vacuum. Then I can just plug that vent line.

The fuel tanks on newer scooters are vented, usually through a check valve, to a vapor recovery canister. If that vent system gets plugged up a small hole can be drilled in the gas cap to relieve any vacuum build up.
