Why do you drive with the choke on? You shouldn't have to do that. My 02 vlx was cold blooded in the winter. I always had to choke until warm, but once warm, would take throttle just fine. Run some seafoam through it and see if that cleans up your carb.What is the deal with cold temps below 40 and coughing and sputtering until warmed up? Also it won't start without having a charger hooked up. It just cranks until the battery is dead. With the trickle charger on all night it starts right up. Any body else see issues like this. It is a new battery this spring and I drive with the choke on.
