New Recall Gas Cap Did Not Fix Gas SMell

[JJW SpyderRider]

So if I've got this figured right; there's about three reasons for fuel smells...
Leaky gas cap gasket
Bad purge valve
overfilling the tank...

Are there any others that come to mind?
The issue of the warranty is interesting...
If overfilling the tank ruins that canister; could that still be considered a warranty item?
After all; if you let it dry out well before calling the dealer; could they trace it back to owner error?

Bob, You might add the leaking fitting on top of the gas tank.

Bob,

No, I started on the ride yesterday with about 3/4 of a tank of gas and didn't refill after the ride. I also am fairly careful not to overfill the tank.
