I'm not here to start a fight ....
While I would not recommend you do this on a regualar basis ...
I once rode for about 100 miles with my gas cap unlatched - no problem bike ran fine.
As an experiment you could carefully put the squirter-straw from a can of WD-40 in the gas tank opening to insure the tank was vented. I will bet you that the bike runs fine. The fuel tank may end up with a slight positive or negative pressure due to temperature changes and the check-valve in the vent line, but IMHO the tank does not have to be pressurized for the bike to run.
Overfilling and screwing up the canister I can see... but I don't think the system needs to be pressurized.
