My bear tracker 250 has some type of issue. It starts rite up and idles great, even revs fine in neutral. But when in gear it's Boggs out really bad and want go 80 percent of the time unless fully choked. Please help ty

 

I'm far from an expert on ATVs but sounds like an air leak around the carb/intake if you need to keep it choke'd... Check your carb gaskets, while your in there give it a good carb cleaning.. I may be way off but that's the first thing I'd check.
