Just stick a jar under the bike and crack off the drain screws on the float bowls, if you're worried about it. Bear in mind if you're using premix though, that there may be a slight oily residue left from the mixture that could, eventually, turn to a gel-like substance... after several months!
Personally, unless you think it's going to be 6-12 months before you use it again, I'd just drain the float bowls. It takes seconds.
As for Les's "labour intensive" method... really?! On an MC21 race bike it's two screws and a couple of minutes max to pull the carbs off the manifolds! (You don't need to disconnect the throttle cables.)
