I would agree with @Frank Angerano , may have a bad heater core or climate control unit.

The cooling system should be full of anti-freeze /water mix .. there is an expansion tank where you fill the system.. When the system is cold and full the level should be at the full mark on the expansion tank.. As it heats up the coolant expands and some is forced into the expansion tank.. Shut down and cool off and it is drawn back into the radiator.. If the expansion tank is too low or the radiator has been opened cold and air allowed in either by drawing fro the too low tank on cooling , or by opening the rad , air will bubble into the expansion tank on warming up. If all levels are right , there should be no air bubbling into the expansion tank after all the air allowed into the radiator has been released after one or two heat and cool cycles .. If bubbling still occurs after everything is normal and cycled a few times , you have a leak in the system. Most likely a head gasket leak. The "smoke" or steam in the exhaust is normal in cold weather , especially if it is wel l below the temperatures where you see your breath .. One on the products of fuel burning is water vapor. It condenses in the muffler when the engine cools and is boiled off as steam when it heats up. . If there is a lot , it could mean a slightly leaking head gasket .. The main indication of that is the level in the expansion tank going down below the add fairly quickly and constant bubbling into the expansion tank.

yep got a laptop. Ok so heres whats going on: Fuel pump hooked back up- no more flooding and it appears to be working It no longer smokes...at all I took the 'snorkel' off the top of the airbox lid and adjusted the carb needle up (richer) to let more fuel and air into the engine The radiator has drained the antifreeze twice so far Heres my theory: The 'smoke' was just condensation because it was 40 or below when it was doing that, now that it quit, it over 50... The antifreeze disappearing: I guess the radiator was drained or leaks because the bike was sitting for a long time before I got it. I'm thinking as the radiator runs, it is sucking antifreeze into itself. I think this because I noticed that there were bubbles coming up from the hose in the antifreeze while the engine was running. Any input would be great! If this is what I think it is, the bike is ready to sell as soon as I clean it up....👍 I will say to all those out there with carbureted sportsmans: If you want more power, Take the snorkel off the airbox lid and adjust the carb needle clip down one notch- My sportsman is scary responsive now, it roars and also spins the rear tires if pegged. Before there was about a half-second delay in the throttle to rear end, now they seem to be directly connected- and my belt is shot too

This is quad crazy not crown Victoria crazy! Lol just kidding. It could be two things. One the fogging could be due to a blown (heater core). It’s a small radiator type coil under dash board on the passenger side. A real bi*** to get to. A tell tale sign is the fogging as well as a wet floor on the passenger side under or on the carpet and a bit of a sweet odor in the car. The second thing it could be (less expensive) is the change over valve. It’s a small valve or damper that’s controlled by the switch in the dash. The control switch you would use to change to defrost to dash vent. That switch usually activates a motor of a kind that moves the flaps inside the dashboard ductwork. That motor can be a pneumatic , electric or cable depending on the year. It’s usually located on the firewall under the hood. In that general area. I’m putting my bet on the heater core though based on the fogging. Hope this helps. Get an Atv. It’s a lot easier and more fun to work on! Sorry to my fellow members but I couldn’t help myself I love cars as well! Good luck!

Here's a kind of long video from my last ride ... so get some popcorn, a drink, a comfy chair & sit down & enjoy the show ... and no commercials !!! PRAY FOR SNOW !!!! ...

one problem.... parents wont let me get a smartphone 😭
