2004 Sportsman 400.......engine misses/skips when cold.......runs great once it's warmed up........does it whether the choke is on or off........anyone have any idea what it might be?

Thanks, Bob

 

Anyone?

 

How cold was it? ... did you rejet for winter per the manual? Did you have fresh gas? Try HEAT in the gas to get any water out, could be water in the gas filter (left side) and once it's warm the ice melts?

How many miles?
How many hours?
Does it miss bad? or just a little rough?
What happens when you give it gas? Better / worse?

need alittle more info. [img]i/expressions/face-icon-small-smile.gif[/img]
