No not if it's air.

The bike doesn't have a choke in the real sense, when you pull the choke lever out, look closely at what happens, it pulls out 4 plungers, they can stick open even when you push the lever back in. This cuts off air at low RPM through the pilot circuit, thus enriching the mixture, so when you rev the bike when it's warm with a stuck open plunger it's over fuelling.
