2008 250 TRX smoking

Hey guys, I pulled out 08 250TRX out of storage since we are going to sell it. Fired right up but it’s smoking a little. We did add some seafoam to the tank last fall but the smokes coming from the engine itself not the exhaust. Any idea what might be causing it? How does this effect its value? It’s in great shape overall, runs strong.

You can (maybe) see the smoke at the end of this:
