I just took my 250x out in the snow recently and noticed it wont idle on its own anymore. Also when I'm riding and let off the gas all the way it will sometimes stall and/or backfire. I think it's a carb problem but I'm not 100%. Please help.

 

Yes it could be a carb problem...if it helps to choke it a little it makes it more certain. Also check your airbox and filter for ice/water.

 

Ok thanks I'll check and try that out.
