I am in the process of ordering a new 2007 America over the next few weeks.
One area of concern is cold (28 to 38 deg F and high 3000ft plus starts and operation). I had a Polaris 600 twin ATV for the farm that was carburetted and it was a hunk of junk

No matter where you set the choke, it would run for 30 sec and stall when cold. The only fix was to keep the revs up to 2,500RPM for around 5min until it was warm. When the EFI models came out a few years later, the dealer did the right thing

and gave me a great trade in price in a 700 EFI model. No problems since.
So the point of all this is does anyone have experiences with the operating conditions I mention on their America's Speedy's or Bonnies? If bad, I may wait to see if an EFI model comes out on 2008, although I prefer carbs. Really don't plan on any cold weather rides but clear crisp days are always good for a ride.
