I took the belt cover off again to try to get the clutches right. There was a ton of fine dust indust in there and the secondary cam was scared up. I put a filter on the intake the second time I had dust pack in there. I'm at a loss here. I'm not replacing the cam again.   The dealer said to snorkel it, but it is illegal here to have them. If there is a DNR officer within 100 miles of me, he finds me without fail every time. I'm ready to call it quits with it. I don't want to pull the belt cover off every time I come back from a ride.

If you have a filter on the intake....then where do you think it's coming from? On my Z8 I still have the OE useless filter in but also have some Unifilter material I cut for the intake grill and because I was concerned about flow, I removed the second stage of foam and left it dry. I get a slight amount of fine stuff in but nothing out of the ordinary or anything that causes a problem. I will say that I need to blow-out that extra filter after almost every rude as it gets ...a lot in it and if it becomes restrictive, the belt and clutches will overheat...don't need that.  Funny that my Kawasaki has it's CVT intake right in front where it gets all kinds of dust with no filtering and it never has any issues except the primary shoes do wear a bit fast...but like 2000 miles. It however has no exposed helix in the secondary to scar. 

I think in time I might consider a full Unifilter over the intake...oiled and everything to ensure 100% clean air but I would also have to consider a helper fan in the intake as the it will need some help. Maybe not a bad idea. Might help make these clutches last longer if you can keep all the grit out and keep them cool.

Illegal to snorkel your ride??? First time I've ever heard that. What's the reasoning? I'd get it in writing from the dealer, and keep it in the glove box. Lol

On snorkel, less incentive to go in the water. Riding in a wetlands is a pretty big offense here. Charge you with a misdemeanor, fine the hell out of you then maybe take your ride. The dealer said they would be "cool" about the snorkels but they have never been cool to me. I have no idea how I'm getting all the dust. It is very fine and might be getting past the filter I have. If I do an oiled type, I will need an easy way to clean it out.

That's like fining you for owning a hand gun that you MAY use to commit a crime !!! Well sir, you DID snorkel this SxS, so that means you HAVE ridden in the water. No, No, No, No ... they can't ticket you for something you haven't done !?!?

We lobby and fight for every mile of trail we have. The groups here are doing a pretty good job but some guys are clueless and take there big yellow machines through whatever they want regardless of signs and trear it up. Gives the antiatv crowd all the ammo they need to take away trails and pass more laws. Seems your guilty of whatever the DNR thinks you did before they even get out of there truck and don't want to hear a word from you.

OK, enough of my contempt for Ranger Dick. I  have an idea but maybe some input. The intake is behind the driver but getting air from a dusty spot. If I can find a surface mount filter cover that is flat or recessed/cut in, I can pull air from behind the seat. When I have to clean or replace it, all I need is to remove the seat and there it is. The hunt is on. Here are some pictures of what I'm working with.

I did find some defects with the ducts. There mold halfs did not line up and they made them off center. This allows them to pucker creating a gap at the joints. I took a heat gun and straightened them as best I could. Something to watch for I guess.

Man that stuff is just ...wow..just another QC let down. How does that get by inspectors?

There wasn't one or they were told good enough. I work in the tooling industry. Parts like this would have never been sent out and the mold would have been sent right back to the tool room. It's sad because it looks like a problem that could have been fixed before lunch. Put it back together again and it might be ok after the heat gun tweak. I shoved bulk filter mesh in the intake then covered it with the prefilter I already had on there. Still looking for some way to get a filter behind the seat.

Hi, I am doing right now the CVT intake and exhaust Snorkeling as I did with the Air Box placing a Rised Dry Pre-filter, will take pictures and show all my "solution".

To start the Intake piece needs to be modified to place a niple for a 2 inches diameter rubber hose (steel reinforced) so the air come from an intake in the back of the drivers seat..
