My K&N air filter doesn't seal up nice and tight to the intake hole in the airbox. I'm starting to question whether or not I've got all the right parts and/or am assembling things correctly. I've obviously got the K&N filter which looks just like the product photo below. The foam patch on the top of mine has a couple of incisions from where the plastic standoff ribs on the outer part of the airbox have dug into it over time.  I've also got a foam ring that's about 3/8" thick, shaped just like the open side of the air filter. It's not attached to the filter itself or the airbox, and I'm not sure if it's supposed to be. When I assemble the whole thing, I have to position the foam ring at the proper spot near the airbox intake opening, jam the filter up against it, hold the filter and ring in place thru the opening while I attached and tighten the outer part of the airbox. This all looks semi-okay until I run the engine for a bit -- all the vibration eventually jiggles everything around and the filter and ring move enough to allow unfiltered air to slip past. Not good!! What am I missing here? Thanks in advance, Curtis | ||

Well, you could either attach the ring to the filter, OR the airbox. Either way, it will help to solve THAT problem. If you wanted, you could also grab some semi soft foam, and use on the back side, to shore up the area that is being cut into, and help it secure better. I dont know THAT much about the airbox, as I had it off the bike within 30 minutes of possession of the bike... Chase | ||

I had the same problem with mine. Rocks and sand in my airbox. I found that the dealership I bought it from gutted the airbox. X1 airboxes do not like to be gutted. I finally just gave up and installed a forcewinder. Overpriced and ugly but very effective and easy to maintain. | ||

You guys never rode dirt bikes? I made the filter better sealing by coating the rubber sealing surfaces with copious amounts of white grease -- standard dirt bike practice in these parts. The grease holds particles that would have made their way inside the filter. | ||

I would toss the airbox. I have to disagree w/ Natex, the airbox is whats ugly-offensively so. I have the Forcewinder, which according to NRHS dyno sheet, provides excellent flow, far better than w/ the box, and at certain RPM's, flows better than no filter at all. It also offers the most knee clearance.It is fairly expensive, but comparable to other systems and you get the breather set-up. I would run the breather to a catch can rather than back into the filter. How could anyone think stock airbox looks good? Besides, the X1 is classified as a "naked" bike, naked means no unnecessary plastic crap. The more parts that are exposed, in my opinion, the better the look. | ||

When I had a similar problem I discovered the allenhead bolt (long and skinny) on the back side was not to be found. After a trip to the local hardware store, that bolt installed, produced a good seal. | ||

Curt the foam filter gasket is supposed to be attached to the filter, as Sparky suggests if you want to stay with the stock air box grease the bottom of your air filter and frequently check the seals and fitler in the standard air box. I did that early on got tired of the mess& hassel and did the Force winder / pipe trick better, toss in a race ecm and re hose the vents its great |
