+1. as long as you keep the carb 'right side up' and nothing liquid leaks out, you're golden.

But if he folded the bars down, turned the fuel cap to off and drained the like the instructions say before you throw the bike in your trunk to transport, should it still leak?

The short answer is no . . . but . . . it is difficult to drain ALL the gas from a carb. Even a little spilled in a closed environment smells forever. You can test the carb petcock shutoff by loosening the two bowl screws and turning the gas off and on. When off, you will see gas squirt from a small hole on top of the bowl. It should shut off completely when turned to off. Be careful not to tweak the float when messing with the bowl (or more exactly the tab that adjusts float height), it is a sensitive little bugger.
Best of luck.

Petcock leakage is going to get more common in the post-ethanol era. Rubber and alcohol do mix...not what you want. A petcock that seals properly will allow you to drain the carb dry and have it remain that way. Replacing the petcock packing washer at the beginning of the season should do the job.
FWIW, I transport my rider inside an enclosed vehicle, draining the bowl by first closing the petcock then running the engine until it dies. That leaves very little gas in the bowl. Removing/opening the drain valve afterward is quick and effective. Believe me, it makes a world of difference. If there's any significant amount of fuel in there, you'll get gassed-out - a nasty, but effective, diagnostic tool.

FYI, constant leakage from the overflow/vent means that the fuel level is too high. If this occurs while riding, you have a float/inlet needle & seat issue. If it only happens when parked & not running, the bike is probably just leaning-over too far.
