ive got an 07 lbz mine has been doing the same thing, But only in the morning after sitting all night. It will fire right up then like 5 sec. later it dies and just cranks then i crack the bleeder screw on the filter housing and prime it a few times and then it normally fires right up fine all day long untill the next morning. Im sure its an air in fuel problem i just cant find anything. So if anyone has an idea where to check i would love to get this thing fixed.
Thanks, Jared
