Viking 700 Gas in Airbox

Hi, guys. Have a 2015 viking with 1800 miles and 300 hours. I had an issue earlier this week with the check engine light coming on intermittently. It went out the last few days but I noticed that my air filter has a lot of gas soaked up in it. I changed the oil and it smelled gassy too. Any ideas what to look at? The air filter has an area soaked with gas probably around 5 to 6 inches long and wide. I remember changing the filter last year and seeing the old one soaked too. We do a lot of short trips but it seems odd to see so much gas in there. It seems to be running ok. Like I said the check engine light is now off. Not sure what that was about. Thanks in advance for your thoughts.

On lawn mowers, it's usually because the carb float is stuck. No idea about a bike engine.

For some reason the crankcase had gas in it, and the level was high enough that oil/fuel entered the air box through the breather line. Why the CC had fuel in it is the question. Wonder if the injector was hung open or something along those lines.
