I think the hose you are referring to is a crankcase vent tube. Put a small filter on it. Do not plug it. Your engine will build too much presure and possibly leak oil. You could run a pipe to the air box from the carb and mount the filter in it. I did this out of necessity when changing to an aftermarket shock. Sorry picture is sideways.
