Hey Guys! I know this has been a discussion before but I can't find any feed back on this. I was thinking about cutting out the top of the airbox and mounting it on top of the filter. So basically there is no airbox. I found some pictures of this mod on other threads but no one has said anything on how well it works. Can someone help out here? | ||

It's a noticeable difference. Spins up faster. A lot faster. Louder, you can hear the intake, as well as the valve train. Go ahead and try it. It's only $35 if you don't like it. I'll bet you do! | ||

well I have the 12 airbox on my 9, so I still have the 9 airbox. Can I use the 9 box to do this? | ||
| Darthane |
The 12 would be better. The open 9airbox may not be as much of a gain as the closed 12, and the 12 box makes power differently. If you're going to do it, use the 12 box. Best of both worlds. | ||

Would a good piece of foam on top of the remains of the airbox suffice, since it would be pressed down on the airfilter by the outer (surlyn) cover? I don't wanna drill holes and use nuts 'n bolts ... | ||

Do the mod, you'll love it...what Glitch said. The only thing I would worry about using some foam, etc instead of bolts is if you live in a hot climate where the sun would beat down on the plastic all day possibly warping or deforming it depending on the amount of pressure being exerted. I don't know what the heat properties of the plastic are really. I've done it to mine and two friends and we all love it!! Later...Odie | ||

If you look towards the bottom on the following thread, this is what I am thinking of doing. WHy couldn't I use the 9 airbox to do this? I dont' understand what the difference is since you are just using something to hold it down. http://www.badweatherbikers.com/buell/messages/32777/72427.html Odie...I think one of the posts is from you. | ||

Look at this old thread. The airbox isn't in that state anymore, but when I changed it the last time that foam came out and got back to its original shape instantly. It's pretty heat resistant and doesn't burn (I checked). | ||

Lazyme21... What makes the 12 airbox better is a little vortex cone that directs the air into the velocity stack. | ||
| Lazyme21 |
ok cool, that makes sense. Thanks! | ||
| Odie |
Lazy, what Stealth said. It's not the outside of the airbox cover but the inside that is different. You can do it with your 9 box but will get a little more power with a 12 box cover. Here's what I did. One stainless bolt with washers and nylocs...Odie  | ||

or this less radical version....although i plan to do odies version at some point  | ||

Given that this is such a noticeable improvement - why didn't Buell do this at the factory? | ||

NOISE STANDARDS | ||

What about the snorkle, what is it, where is it? I was told to remove it too. | ||
| Odie |
See the triangle shaped hole to the left of the air filter? Grab that rubber piece (snorkle) on coax it upwards and deposit in trash.  | ||

Odie, What are the 2 hoses extending through the filter for? | ||
| Signguyxb12 |
one is for the fuel tank breather the other is the servo motor (xb12 only) | ||

Bonesbuell, what Odie said about the snorkel location. But, don't throw it in the trash! Remove the snorkel and cut off the top portion, the section that fastens to the airbox base plate, down to just below the taper. Wrap a strip of insulating foam around the bottom that fits in the frame/tank opening and reinstall just this piece. This will still give you the enlarged air intake, but provide a seal to reduce the air leak and cut down on the noise (what you hear through the air intake cover from on the bike, not the sound heard from off the bike!). Mike. | ||

Interesting. Do you have a picture of that xb9er? | ||
| Xb9er |
I knew someone would ask me that. I don't have pictures yet, but I can take a couple and post them before midnight tonight. Mike. | ||

With the airbox conversions displayed above, and on previous postings, would there not be some intake issues while riding in the rain? Seems a lot of moisture can get through at the gap between the airbox cover and the frame/tank??? Anybody who has done these conversions ridden in a rainstorm yet??? Just wondering... | ||

Just put my airbox under the knife (well, dremel tool) last night. Got the necessary mounting parts this afternoon at Walmart to pin down the leftover parts, we will see how it works tonight. I am cautiously optimistic. As far as water goes, you shoulda seen what my M2 looked like with the forcewinder, and I rode it through some absolute frog chokers. The only runnability issues there were related to a spark plug wire falling off, not water intake. Don't think you could do anything to an XB short of running it into a lake to stall it from water in the intake. Thermal management is probably a bigger issue. The intake will be sucking hot air from around the engine, which will cost some power. Isolating the hot underneath from the cool top and intake would be a better use of time. That's what the FAST system does (among other things). I like the snorkel trim idea. I was chicken to cut mine as the bike only had 300 miles on it when I pulled it, and wanted to be able to return it to stock, but I am quickly getting over that  | ||

Thermal management solved.......  | ||

I cut the top piece off of the snorkel and made the outboard edge knife sharp with a dremel tool and then re-installed it to seal the airbox lower to the intake hole in the frame. Worked like a charm and the rubber was easy to shape with the dremel. xbolt12 | ||

Thermal management solved....... I've got one of those! Thanks Odie! | ||

You are doing some cool stuff there Odie... Glitch, weren't you going to get that pipe dyno'd? | ||
| Odie |
Thanks guys!! | ||

Hey thanx Mike! I'll be hobbying some more this weekend! |
