Thanks for the offer Ronnie. I'll keep it in mind. Not sure yet if what I'm experiencing is really not normal. Unless the cap vent is "one way only" i.e. just to allow air in and not out, I don't see how fumes would not escape from the vent.
The gas cap is non-vented. All the air in and fumes out, go through the Evap canister. This is why the canister has a fresh air IN port on it.
Hmmm. Thanks TD. This changes my thought process. I'm careful about not overfilling. Have not noticed gas wetness around the lower cowl (no belly pan either). More investigation needed.
Reach under the lower cowl and rub your finger across the inside of the lower edge, then sniff your finger. You should not smell any gas residue. If you do, it has dripped out onto it at some point from the canister.
How long before the EVAP canister dries out? I over filled mine a few days ago, and now notice that it stinks up the garage. It's not a raw gas smell, but like the cat smell as above. I won't over fill it any more. How long before the smell goes away?

You should get no raw gas fumes from the bike, the Evap system catches and holds the fumes from the tank with charcoal. The two main causes to smell fumes is a gas cap that is leaking the fumes or too much gas was put into it and the Evap system got liquid gas in the canister. If the canister gets liquid gas in it, it will drip out on the inside bottom of the lower center cowl and the smell stinks up a garage pretty quick. The owners manual warns about filling the tank above the bottom of the fill neck and this is to keep the liquid gas out of the Evap canister.
I read about the smell being caused by overfilling the gas tank. (I did it all the time) No problems since I stopped doing that.
It was really bad, because our air conditioning intake is in the garage, and it would fill the house with that lovely smell!
