The bike is an 04 6RR. Fires up immediately when cold. However after you ride around for a bit and everything gets up to temp it doesn't want to start. You can crank and crank and usually it will go eventually. Otherwise I've just been opening the throttle some and it will fire up not too bad. Dealer says this is because of a vapour-lock type condition on these bikes and that they all do it. However, I know from snowmobiles that it's usually a symptom of worn rings. Bike has just over 25k kilomters, and has been doing this for almost as long as I can remember. I do not recall it doing it when new.
