The generic design basis is to capture fumes in activated charcoal when the bike is parked and hot, then allow them to be drawn into your carb at the next restart.
We have one bike with (gravity), one without (pumped) and neither one stinks up the garage. We are not fans of pollution control junk but there is no plan to remove the one canister we do have - "if it ain't broke, don't fix it".
But, if you have a compulsion to tear stuff off your ride, send it to the dump and let us know what happened, if anything. That will satisfy everyone's curiosity.
The EVAP system actually might improve gas mileage 'cuz it captures fumes that otherwise might just blow away and feeds them back into your intake.
Not really sure how much benefit it might be, but since you end up using the fumes instead of losing them...
