Yes, there's been lots said on this topic, but what specifically should I be looking for with regards to the air filter on my new S? Should I be looking inside the airbox for trace amounts of dust, or looking around the connection areas to see if it's come loose. Can somebody please summarize the stock air filter issues seen over the last couple years. Are there any body panels that need to be removed in order to properly inspect for problems?

Edit: I was reading about liquid gasket to help keep the bellows from cracking open slightly (although it appears tight)...So would that be painted on with a brush while in place, or removed and added off the machine. Who has done this and how has it worked?

Getting dirt in the airbox is going to happen, the goal is to not get it past the filter . Some of the reports talk about dirt getting past the filter. If you grease the tube and washer where the filter go, shouldn't be a problem. I think the major issue is dirt getting past the boot between the airbox and throttle body. With the air filter mounted to the frame, the boot can get torqued when the motor shifts and cause dust to leak past the clamps on the boot. This seems to be the biggest culprit as far as I can tell.

Some use a bigger clamp. I have read about sealing the boot the to the air box and throttle body but haven't seen any details on this. Another option is to replace the entire intake system.

Right....I guess I meant to say through the airbox itself past the filter. Good clarification. I've read a bunch of past posts on this. I have not heard or seen anybody post pictures of their liquid gasket repairs to the boot. Would be nice to see some. I'm going to pull it all apart today and see for myself what's going on. Maybe Polaris changed some things for '11 in the air filter dept. Thanks.

I've read so many filter threads since I joined here, and I still don't remember a definitive answer as to if the root problem has been corrected.

You can get a good look into the throttle body by pulling the filter and shining a bright flashlight in there. A more thorough inspection will require removing the bed.

I had to see for myself and check out the situation. So today I took the bed off and disconnected everything to check it out. The TB was very clean, but not 100%. I can only figure the very slight particulate was getting past the OEM paper filter (visible super fine silt on a white cloth). It had a very slight residue after nearly 200 miles. IMO, based on what I saw and physically felt...there is very little chance the rubber boot off an '11 could pull off and allow direct injection of unfiltered air. It was very solid and tight. The rubber boot actually had a lip and it it bounced over an edge, making a seal. I literally pulled on the boot and it would not budge from either side. I attached a picture of the rubber boot. Wanted to check if other boots have the rubber wings on the sides and if the boot moves over a lip to seal it. It kind of popped on when pushed in place. Do other MY boots have these wings pictured?

Also attached a pic of the inside of the airbox and boot. Can't believe how much grease was in there from the factory.

I had looked at my 2011 boot also recently and it looked the same. This was after some 80 miles.


later
