Good idea to remove snorkel?

Since I removed my snorkel, what do I need to do with my crank case breather hose? I just have it open. Is there a filter that I need to put on this? Will it get clogged easy?

Also, I put outwear material over the snorkel delete. If I put back on the snorkel, would it significantly help to not let water in? I had that stupid sputter problem.

Removing the snorkel can increase air flow enough that re-jetting may be required - but performance will be increased too, once proper jetting for the change has been achieved.

So it's actually a restriction. Should I put a filter on the breather tube? Stupid question, but does that breather suck in air or blow out air?

Yes you can put a filter on the vent tube, this will allow the crankcase to breathe.
The reason for your sputter is because you changed the air restriction going into the engine's intake, removing any part of the stock air box will require rejetting, but the rewards are worth it.............

No, my sputter was a result of water getting in the airbox. I have rejeted. I was just wondering if putting back on the snorkel would help eliminate water getting into the airbox even with my outwear over the snorkel hole.

Also, I want to know if I should put on an air filter for the crankcase tube. Do you put this on so that debree doesn't get lodged in the tube?

The snorkel is there to help keep water out. If you're going to do a lot of water riding, you may want to leave it. If you, instead, want to increase performance, remove it and rejet.

If you remove, put a filter on the breather tube - it has little airflow, what's there is usually out, but a filter will keep dirt from migrating in.

Could I just use any air filter from an auto store?

drill a couple of small holes in the bottom of the airbox so any water that does get in the box will drain out.
personally i hate using an airbox. and i ride in water,mud and trails with no problem
