Yeah, at least one of those hoses is the bowl vent, and blocking it off should actually make it run lean as you'd get a vapour lock kind of situation where the low pressure in the throat drawing fuel from the bowl is now fighting the low pressure created in the bowl.

The other one might be the SOS hose and must be blocked off if you've bypassed or replaced it. Which bike are you working on? The neither of your bikes should have the SOS unless you've got carbs from a later year.

A picture would help.
