All the foam pieces of my airbox on my Widetrak LX keeps getting plugged with ice crystals and snow when I run in really deep powder, or when snow falls on the machine. A few days ago I tried to start my machine and it wouldn't idle for crap (that's how I found out). Upon pulling the plugs, they were wet and black with carbon. Apparently, all these darned pieces of foam were too plugged up with moisture and ice crystals that it made the engine run extremely rich and cold. Once I cleaned the plugs and pulled all that foam BS off the top of the airbox, the problem has seized to exist BUT the motor is now exposed to taking in snow.
I'm tired of these air box problems and was considering a couple universal K&N air filters that are large enough to be clamped to each carburetor. I took out a set of calipers and measured the outside diameter of the carbs and was thinking of simply purchasing a couple universal K&N filters. Would this be OK?
I don't like messing with such a reliable stock motor like this 500 liquid BUT I think this airbox crap needs to go. Any suggestions? Because of this airbox issue, fuel mileage has been effected too, that was the second sign that something was wrong.
