I have a 2007 DL650 with 43k miles that is hard to start every time it sits overnight in cold (40dg) weather at high altitudes. Whenever it does this I have to hold the starter button down and open the throttle a small amount untill the bike idles on it's own. As I am doing this I can smell gas coming from the engine but I can't see it. This bike has had a history of idling weak when the engine is cold from sitting overnight and when the weather is really cold. Other than that the bike starts fine in all other situations.
