My 2004 Polaris switchback has had an engine swap from a 700 to an 800 and am now having problems with it overcooling in powder and fouling sparkplugs. It runs fine on trails but immediately starts running cold in powder.I have changed the thermostat in hopes it was a quick fix. No such luck. Anyone have similar problem and shed some light on what the problem may be??
