Ok, so what can be done to prevent this? |

}Ok, so what can be done to prevent this?
For starters I'm going to deburr the plastic lip around the filter sealing area. Mine isn't all that smooth in places. Along with some kind of rtv sealant to create a better seal, especially along the bottom on both sides of the filter, I think that should suffice.
The throttle body gasket could be permanently attached to the air box base and still allow you to remove the whole thing as one unit. I'm just not sure how to go about doing it. The seal between the throttle body gasket and the base plate plastic seems to be the weak point, not the seal between the rubber gasket and throttle bodies.
I'm basing all this on my own experience with removing the airbox some 3 or 4 times now and noticing where the sand is and how far past the seal it's traveled. YMMV. |

Has Buell/HD been notified about this issue? They should be very interested in solving this, due to potential warranty claims. |

I doubt seriously that there would be any warranty claims. The motor is not likely to fail from the small amount of dirt that gets past the filter. The majority of owners ride on paved roads and aren't likely to notice and may never remove the filter. |

Aren't there any fender extender's for Buell ? |

Guys,
On the AT sensor temp, that sensor is down under the front fairings by the front head. It won't matter how you arrange you air box. The sensor will still read the air at that spot. I know that on my 1125R, the temp reading will increase as I sit in traffic, and goes back down when I get rolling again. If you remove the air box covers then we all know that we will get heated air from around the motor. However, the AT sensor readings should still read the same as before the air box mod. I think that once they release the bigger air box that is found on the 1125RR's then we will have these issues with it. I like that idea though, Moose.
Moose, will the lower half of your air box fit? More interested in the rubber piece that seals it to the tubes and body. What parts are hitting? |

You'd have to cut the front hump off for the filters to fit. The lower gasket will not work with these filters because the filters seal where the lower gasket would normally be. You could easily put some of that sticky heat shielding on the bottom of the airbox and cut two holes for the throttle bodies. |

The RTV set for approx 8hrs.
After some pulling, peeling, and a little finesse, the silicone was only release agent to pull off clean.
The RTV produced a nice form for fitting to the filter seal and I would suspect this could be a
viable repair for those of you with dirt ingress problems through the air filter seal. YMMV
Sacrificial filter, may you rest in pieces...
Mike, do you think the silicone spray lubricant will allow me to pull the filter off without messing up the new gasket? How easily did it lift off?
I tried it today, but I started to get worried it would mess up my K&N, so I pulled it off to early. The gasket hadn't setup and so I had rtv on the filter and the filter box. I tried with synthetic grease and it seemed to allow me to remove the sealant from the filter, but it did not lift off as easily as I'd of liked.
The K&N filter is not made from the same material as stock. The stock filter is some kind of spongy rubber and the K&N is some kind of silicone material.

I would say yes I "think" so. If anything since the K&N filter has a more dense rubber gasket it may pull/peel off easier.
Did you put anything on the rubber before you tried this???
The hardest part I can think of may be finding a place to start peeling it off. When it was on a flat surface I started at the corner and just worked my way around. I put the K&N on mine but never even looked to see how it seals or whether there is room to get at the corners. you may just want to remove the filter housing so you can get in from the inside and manipulate it from both sides. If when you do this for real make sure you use silicone spray (spray it on right before you put it on the filter housing and don't wipe any excess off), then let it set up for a day. and take some pics for us.

I need to get some silicone spray, but I did a test with some things I had and I can tell you that wd40 doesn't work.
How does this idea sound? wrap the filter tightly in saran wrap and spray the saran wrapped filter with silicon spray. The filter needs to be pulled up at the bottom to remove it, you can't just pull it out because it fits down in the grove.
The saran wrap will obviously keep any rtv from sticking to the filter, then you just have to worry about removing the saran wrap from the air box.
The stock filter is more porous than the K&N. It doesn't surprise me that it ripped like it did. I don't think you could rip the K&N filter before ripping the rtv. |

I would think putting a piece of waxed string in a corner or all corners so you can get it started peeling off. you can always smear a little rtv in the void the string leaves. Saran wrap... I don't know. I'd test that before I went and tried that. The filter may come off and you may be left with saran wrap stuck to the rtv.
If you look closely at the pics I posted you can see black residue on the filter where it released for the 3 sides that didn't work. The side I used silicone on showed no black residue and released the easiest.
Another idea might be to seal 1/2 the box at a time starting from the top of the arch on the airbox down one side and back up to the top of the arch. You would then have 1/2 an air filter not glued to the airbox making it much easier to peel off, then do the other half the next day |

permatex black high temp rtv does not stick to saran wrap. I was quite surprised. I tried vasoline as well and it seems to work great. |

Could anyone take pics or measure how far above the stock filter height the k&n filters stick up?
If it is not too high, couldn't you:
Put some kind of thermal barrier between the bottom of the air filter box housing and the top of the k&n filters, then take a Heat Gun and gradually heat up the are of the box above the filters while applying pressure, and essentially mold the stock cover to the top of the filters? |

Hey Moosetang,
Have you sealed it up on the housing yet? I'm glad you tried a few different options and got satisfactory results!
It's always good to see something work when someone else thinks it won't!
Cheers

I used the saran wrap, it works the best for removing the filter without sticking. The only problem with the saran wrap is it's hard to keep wrinkles from showing up in your rtv and it can rip at the corners when installing the filter.
There is a big gap on both sides below the filter. this is where sand was collecting on my bike and eventually working it's way past the filter. I haven't removed the filter again to check for dirt, but I'll take some pics when I do.
I think using some foam weather stripping would work good also and be a little easier to install. |
