     Tripp  |
apparently the air filter replacement element (for the carbon fiber race kit) is unavailable does anybody know if it can be replaced with a SE or K&N? | ||
| Josh_  |
The original Buell Race kit came with the same K&N filter the Screaming Eagle kit did. Later they changed to a wider K&N filter. I'm trying to find the K&N p/n but haven't got it yet | ||
| Tripp |
i must have the wider one ,i think it's #P1213.g but i believe they're discontinued. | ||
| Aaron |
We have them ... (303) 833-4500 Available in 2" or 3". We're using them in our new air cleaners for '04-05 Sportsters. | ||
| Josh_ |
Damn, been a little busy adding products Aaron? | ||

Cool part Aaron. I see a sportster dyno on there with a 1250 kit, but still not particularly thrilling dyno numbers. Why are the sportsters so much worse then the XB's? Do they have different heads / cams? Or is it just that lousy sportster exhaust? | ||
| Aaron |
Bill, that bike has low hp numbers because other than the 1250 kit, it's bone stock. 883 heads have itty bitty valves in them, the stock pipes are really bad, stock ignition, etc. I had it apart to make some measurements for the new engine kits and we went to go put it together and I had some cyls and pistons laying around and thought what the hell, I'll just toss these on it. Damn thing had 39hp as an 883, so believe it or not, it's a bunch better than it was. I have a plan for the bike, to do things in stages (people really like to see that), but not enough time. Kind of a bad deal on this air cleaner because with a more hopped-up motor, the air cleaner would really shine. But I'll get there, eventually. Josh, yes, but never as much as I should. It's time consuming as hell to come up with new products, between designing them, making proto's, testing, going back and tweaking the design, sourcing parts, etc. Something like that air cleaner looks simple but in reality, there's a lot of hours into it. 'Course, once it's done, it's done, and hopefully, it makes money for you from then on. Just as an example, cheapest I could source the standoffs was about $5 apiece. So I just tooled up to make them. It took me several days to design them, get fixture'ed up, make'em, and tweak the design and so forth. But now I can make them for about a quarter each. And I'm making exactly what I want and I can easily change the design as needed. I'll go ahead and do a version of the air cleaner for pre-04 Sportsters and tube frame Buells as well, just because it almost falls out, fairly simple to derive them. But it's a quickly drying up market. The thing with the '04 is that the "other" stock-cover based offering is, um, leaving something to be desired (how's that for diplomatic?), and that's created an opportunity. But anyhoo, one of the versions uses the same 3" element that came with the race kit air cleaner, so I thought I'd let Tripp know that we carry them. Not sure if we have one in stock at the moment but it only takes a couple days to get one if we don't. | ||
| Josh_ |
so that's the stock cover and you made a backing plate, standoffs and "top plate"? I always wanted a cover that didn't screw to the stand-offs since that tends to loosen them and I always wind up needing a hex wrench in the back of the airfilter (we all have our problems) | ||

Thanks Aaron, the XB9 dynos with the 1050 kit were so good it suprised me to see the sportster that low.
Note to self: Try and park my XB somewhere near where Aaron is working  | ||

What they hey, bring it over Bill, we'll mess with it Josh, yes, you've got it. On the earlier bikes, as you know, the ham can cover acts as the front plate, sealing directly to the filter. But the '04-05 cover is an odd shape and it's not designed to sit flush against an element. So I made a lightweight plate that sits in between the element and the cover. What really makes the air cleaner work, though, is the back plate with the radius ring. I got my eyes opened big time as to how important that is the first time I tested a "Frontier" against a Race kit air cleaner. Same element in both, similar design, you' think they'd have similar performance. But it wasn't even close. The Frontier kicks •••. Even on my M2, at over 120hp, having the Frontier in place costs next to nothing on the dyno sheet. Only air cleaner I've ever tested that I could say that about. Well, until now | ||

thanks for the info aaron i'll be in touch! | ||

It is a stock K&N filter, not Buell specific at all. The same filter element is used in the Westek air filter. Replacement elements have been on the American Sport Bike site forever, it's part number 5155, here Its interesting that this filter has been used in oval air cleaners forever, but it isn't even an oval shaped filter, more like elongated D shape. But they're flexible, and fit into oval air cleaners easily. Al | ||

>>>Try and park my XB somewhere near where Aaron is working Never a bad idea....  | ||

Tripp--try BMC, part number 240/15. Exact replacement shape, cotton/gauze with gasket included. Better quality than K&N and identical to the filter that comes with the Buell kit. | ||

Aaron, just curious if you had ever played with the idea of a radius ed cone extending toward the mouth of the carb to help "direct" air flow, and i use direct loosely. maybe better said to control air velocity and and help create a more consistent draw into the mouth of the carb. I had some success with it making a venturi for a 8 position "pick an place" turret head assembly on a surface mount inductor line. I wounder how well it could help a carb, basically a mating piece to your "radius ring" but attached to the cover. another quick thought, might not be as effective on the 3" filters , probably better suited towards the 2" or stock set ups . just a thought to ponder,, thanks for you time and patience, aaron | ||
| Aesquire  |
Aaron, have you ever tested the stock breadbox setup for a m2 or S3? I've modded mine with the K&N replacement & venturi ring. Did I just make it louder, or did I accomplish anything? | ||
| Aaron |
Aaomy, I've seen those setups, and it's in my plan to test it and see if I can find anything, but not, not yet. Aesquire, nope on yours, too. I know it's a real popular thing to do and the X1 race kit air cleaner did pretty much that if I remember right. I suspect it helped, but I've never actually tested it. I was never fond on the breadbox just because of the looks, I don't care how it worked I wasn't gonna leave that thing on my bike! | ||
| Al_lighton |
They do make good right side crash bumpers, though! I'm with you, no way that big ugly thing was staying on my bike. I applaud the engineering that went into it to make the bike pass EPA noise testing, but the only thing more hideous than the S3 airbox was the X1 airbox. | ||
| Henrik  |
How about this: since we now have the venturi ring to improve air flow into the carb mouth - and know it works. How about an air filter cover with a cone similar to the air box on the XB? I guess it's similar to Aaomy's idea, just different It might be something that could be cast or spun out of some sort of poly and then glued into the existing cover. Of course the filter height would influence cone height above the intake, and some flow testing would be necessary to determine the best air filter/cone height combination. Now, who do we know with a flow bench, modelling software and machinery to mock something like that up ... ???  It would likely sell to the Big Twin and Sporty crowd as well.
