I just purchased a new 06 ES 4x4 yesterday and I was riding it around my yard and when I went to stop to downshift to 1st or neutral it would go dead. 2 miles total on the bike. Does this sound like the carb new and not broke in? I also let the motor warm up with the choke all the way out and it would do the same thing, even with the choke in. Any and all help is greatly appreciated!
