Custom Snorkel
 

I am wanting to snorkel my bike, while I am already doing some work on it and the plastics are off...my question (may be stupid) is do I need to snorkel the crankcase vents or will I be alright just adding a snorkel line and running it out the atv? My air cleaner is under the seat , while my crankcase vents are on the side of the bike...if I don't have to worry about the crank vents ill just drill a new hole in the air box and run the pipes
