Another question on carb air pipe hoses

[Blake]

 

 Some small amount of fuel (drops) come from these air joint pipe hoses attached to the Keihin carbs after a longish ride or hot weather. I get some gas smell from what I think must be the fuel cap vent because of the fuel expansion, but also from these hoses connected to the air pipes. 

 

Is this normal or will I burst into flame while riding?

 

 Captain 80s you mentioned charcoal canisters which I have on my 2014 800. Is there a canister that could be adapted to this bike to prevent the gas smell. I have to let the the bike cool before putting it into the garage. 

 

Thanks all for any help.
