Most likely need to adjust the valves... better left to a mech. Easy to do if you know what your doing but a pain if you don't

This is only a hunch based on my experience with a 2003 Polaris Sportsman 700.
The air intake to the air box is tucked up under the body panel. It is located in such a manner that when going through water, the steam builds up at the top of the body panel, smothering out the fresh air and replacing it with hot wet steam.
Re-route your air intake out from under the body to a location that will not trap the steam and remain fresh, cool and dry. This goes for any ATV with this issue as a possibility for the symptoms.

My bear tracker was running fine then all of a sudden will go into gear and not move but can push it while it's in gear what could be the problem?

You did not mention where the spark plug is when you see this blue spark, If it's still in the head with the spark plug cap on the spark plug.. replace the cap/wire/coil - probably a one piece unit. ..now, If the spark plug is out of the head, and the blue spark is jumping from the porcelain tip electrode straight to the curved tip electrode - that is GREAT! THE SPARK MUST jump STRAIGHT across the electrodes... sometimes it's really hard to see if it's jumping around the side of the porcelain tower, then to the tip..this is a fouled condition and it won't run - even though its a bright blue spark!! Seen it too many times!!
