On the right side of the bike, near the petcock, there are 2 parts:
. A small white filter that goes to the airbox
. A large black one that follows a similar path
1) Can someone ID them?
2) And how long is their useful life?
I think that's the charcoal canister that is part of the Evap system. You will see gas drip out of that hole to the left if you overfill the gas tank and don't have a vented gas cap.
