I have an '04. My bike starts on about the 4th or 5th kick when first started cold. For some reason, if it stalls when it is warming up after I started for the first time during the day, it is very difficult to restart. But then, when I finally get it restarted and warmed up, after that it runs and starts fine for the remainder of the day. Does anyone know what causes it to be so difficult to restart when it dies when it is warming up after being started the first time?
