Now that I have a direction to go with my exhaust, I am going to need to figure out why my 4 wheeler is so cold natured. When it is first started, it will die unless choked all the way and you hold down on the gas. I don’t see any smoke (or smell oil) out of the exhaust.
It almost seems like the idle needs to be turned up a little but I can’t see an idle screw. The guy at the Polaris dealership said that my bike was EFI but if it has a choke, doesn’t that mean it is carbed? Also, I don’t hear a fuel pump whine which makes me think that the pump is either bad or it has a carb.
Another Polaris tech said the spark plug could be going bad, causing the engine to not want to stay running until the heat/compression helps with combustion. I have a spark plug and will try to get it swapped out today or tomorrow depending on what all I have going on. Seems like a long shot to me, but doesn’t hurt anything to slap a new plug in there.
So to sum it up, once it is up to operating temp, it starts on the first crank, and it doesn’t lose any top end power when riding… just doesn’t want to stay running before coming up to temp.
