What can you tell me about this 550xp cold starting issue? That is the only issue I have had with mine? Is there any recommendations here? It's hasn't been that bad, only that a quick blip it wants to stall, after letting it warm up for a minute or so, it is good to go, seems a bit rich as I see a bit of smoke on start.. really would love to have the diag tool so I could see what it has to show think I will ask my dealer if he got one yet.
I don't see that as an issue at all. So it has to warm up for a few seconds. The 346 is no different. After it warms up for a few seconds, throttle response is perfect.
