BUT.... park the bike full of gas and as it expands actual liquid gas can get pushed into the charcoal can and even dribble out. This is practically guaranteed to happen if you really top it up all the way. Not going to hurt anything (except for the usual spilled fuel precautions), but it will then take FOREVER for the charcoal can to purge itself and you may end up smelling fuel vapors for quite a while. Sniff around the chin "spoiler"; I bet you will trace the vapors back to the overflow discharge hose off the carbon can...
