I'd also agree with the other lads. If you never had to use the choke in any conditions that would suggest that the bike was running rich. Did you say you put a new air filter in recently? Maybe your old filter was causing a bit of a restriction to air flow and that was causing the bike to run on the rich side and now that you've changed to the new filter you've got more air flow so you need the choke on cold start ups which is the way it should be. That's all guess work though.
