I've been contemplating fabricating up a right side air scoop from a used left side air scoop. has anyone done this or have any tips for doing this? | ||

Unless you have some sophisticated 3d modelling/copying software then a left side scoop will be little use to you other than as a guide for size and shape. It would be impossible to modify a left side scoop to fit the right side simply because it needs to be completely 'reversed' plus allowance has to be made for exhaust routing etc. far easier to buy one of the many options already available surely? | ||

I too contemplated such a project. Unless you "just" need something to do with yourself and time. Buy one from American Sport Bike, Trojan or fellow badwebber Ron Criss(I think is his name.) Or, I'll sell the symmetrical scoops (left and right) that are on my bike. PM me if you are interested. | ||

Before adding a RSS, I'd read what Abe has to say about it in this months edition of Fuell's ASK ABE. I'm not putting one on now after reading it. Using a scoop that's too large will not direct the proper amount of air over the fuel rail and could cause overheating that could lead to vapor lock and ping. | ||

What about all the bikes with the stock RSS that ping? Just throwing that out there. I don't care what's on there. You have the gas tank around the engine. That fuel will always get hot. | ||

Frankly, regardless of where you come down on the issue, a good deal of this conversation is simply poor manners. A couple folks need to come to New York City and negotiate with the Teamsters and the Ironworkers for a while . . . it's a good way to learn tact and to speak in such a way that you achieve your goals. I can just see walking into my 8:00AM meeting tomorrow and accusing Ken Klemmens of "towing the union line". Talks would . . . as they say . .. "break down quickly". I'll win. But not by belittling anyone. Simple manners. I had a similar thing happen several weeks ago when my name was brought up in a meeting at Harley-Davidson. The person, rather than say something factual like "Court screwed up" or "I don't like what Court did" instead decided to get personal. Guess how receptive I now am to the project? | ||

Frankly, regardless of where you come down on the issue, a good deal of this conversation is simply poor manners. What the heck are you talking about, Court. I don't see anything said in the above seven posts that even remotely comes close to the "poor manners" exhibited on posts elsewhere on the BadWeb. | ||

Using a scoop that's too large will not direct the proper amount of air over the fuel rail and could cause overheating that could lead to vapor lock and ping. Using a larger scoop actually directs MORE airflow over the fuel rail, so I would be very suspicious of any article that says otherwise. Especially in a factory produced publication that is hardly objective to start with. I have never heard of anyone suffering from the symptoms described above after fitting a right side scoop, and after all the countless threads and posts on teh subject of RRS I think somebody might have chimed in about it if it actually happened to them don't you? | ||

Trojan, What I think was meant was that the airflow from the left and the right would cancel each other out and result in no or not enough airflow over the fuel rail depending on how big the scoop is and how much it flowed compared to the original setup. | ||

Trojan, What I think was meant was that the airflow from the left and the right would cancel each other out and result in no or not enough airflow over the fuel rail depending on how big the scoop is and how much it flowed compared to the original setup. I can kind of understand the theory of it, and at low speed the airflow going through both side scoops will be reduced substantially anyway. However if you actually look at the shape of the stock left side scoop you'll see that it directs the majority of the airflow straight onto the left side of the rear cylinder. The airflow is then directed straight out of the back of the frame past the rear shock. The stock right side scoop doesn't seem to do anything other than fill a gap. With the larger aftermarket scoop fitted it will undoubtedly flow more air over the fuel rail and onto the rear cylinder. Hence in practical terms the faster you go the more air will be flowing over this area (Yes I know in theory that there will come a point where it reaches maximum velocity and volume, but for all practical purposes it will increase as you increase speed). As both the right and left scoops direct air across each side of the rear cylinder and out of the back of the frame through the same opening, they cannot cancel each other out as they never conflict. In much the same way, air flowing over the left side of a fairing does not conflict with the air flowing over the right side until the two airflows join behind the bike. If you were to design a right side scoop that somehow directed air directly into the path of the left side scoop then it may cause some 'cancelling out' but that is not the case with the current designs of scoops available from various sources. Buell have themselves proved that the argument put forward by Abe is wrong in their design of the 1125R. Airflow goes through the scoops either side of the bike and exits the frame in exactly the same place as the XB. If anything in theory this arrangement would be worse, as it is flowing warm air from the radiators over the engine (albeit watercooled) and fuel rails etc, rather than the cold air on the XB scoop setup. | ||

I sent a email to Ask Abe about the right side air scoop. My problem, and I hope it will be taken care of with a right side scoop, is to stop the hot air from burning my right side thigh. It does get hot at slow speed and long stops at lights. Abe was concerned about the fuell rail not cooling enough. Mine is my personal fuell rail not getting enough cool air, it does get hot!!! | ||

My problem, and I hope it will be taken care of with a right side scoop, is to stop the hot air from burning my right side thigh. RSS will help even at low speeds, until you stop. Heat barrier on the fuel rail solved the roasted right thigh on mine. It and a ceramic coated header dropped temps on my right thigh by 30 degrees. Best 24.95 I ever spent. | ||

Sath Posted on Monday, November 26, 2007 My problem, and I hope it will be taken care of with a right side scoop, is to stop the hot air from burning my right side thigh. No, it will not. | ||

It does get hot at slow speed and long stops at lights. You have answered your own question I'm afraid. The right side scoop will funnel cooler air through the right side of the motor and frame rail only when the bike is moving fast enough to actually get the air flowing. I'm not sure exactly what that speed would be but would imagine that it is over 30mph. Consequently at a standstill and at very low speed the scoop will make no difference for what you are wanting. As Treadmarks has said, ceramic coating the exhaust is the best way to keep this area cooler. | ||

I swear I'm gonna stop chiming in on RSS threads... I want to clarify something brought up in Abe's article in the new Fuell (which sparked the nastiness in the other current thread) and also by BadWebbers when discussing the subject. Unless I'm mistaken, the "fuel rail" referenced by Abe (and also by an Anony last year in a similar thread) is the device located on the throttle body which supplies pressurized gasoline to the injectors. At least that's what they call it on cars. If that's what Buell and Abe are saying the stock right scoop cools at low speed when the fan kicks on then I can understand their reasoning, to a point. A negative pressure generated at that location when the fan activates would seem to pull air from the stock little scoop across the fuel rail where it would join up with the air being sucked through the stock left scoop. My question which has always gone unnoticed during the grenade tossing is how air entering the stock right scoop from the vicinity of the front cyl head and exhaust header cools anything? I think BMC's concern is that a big RSS at low speed wouldn't allow enough air velocity to do the job designed into the stock little one. If so I can see their point there too. And no doubt they've tested the different options, I don't challenge any of that. But in 30k with a big RSS during many many rides in 100 degree+ my Uly has never vapor locked. Two-up, with three cases of gear, fan actually cycles. In fact maybe the RSS is actually prolonging the imminent death of that fan which has been rattling away for months now, probably because it actually rests once in a while. If anything my right leg gets a little warmer because the RSS is blasting fresh air at the front and right of the rear cyl head and exhaust header. | ||

Aww, don't stop now  . I rode the 'Bolt last week and noticed that in 38deg weather I get some real nice heat warming my shins if I hold my legs in tight. I also noticed that my rear feels some warmth transmitted through the saddle. So along with heated grips (TU Michael) I have leg warmers and bun warmers (TU Abe). Don't know how the last two would be affected by an RSS since I don't have one (hint, hint) but I would be willing to do some seat-of-the-pants testing  along with my Gerbings. I understand (from years of development work in automotive, aerospace, appliance and electrical motors) that it's only real-world testing but, it's FUN! That is something I missed in the corporate testing. Anyway we are fortunate to at least have some insight to what happens to our Buells before we get our sweaty little hands wrapped around the grips and have our personal fun. Thank You Buell Engineering for taking care of the Buelligans in us all.  . Time2 get back to this corporate "fun" Neil S. | ||

Manimal, You asked: I've been contemplating fabricating up a right side air scoop from a used left side air scoop. has anyone done this or have any tips for doing this? Now I haven't done this yet, but I have thought about it a bit, and here is what I'd recommend: There are only three choices for RSS material: injection molded thermoplastic (like stock which you can't do), composite laminate (fiberglass, kevlar, carbon or combination there of--like all aftermarket RSS which you CAN do), and aluminum which you CAN do). Now I've done some composite fabrication in the past (see www.ryanrodco.com) and if you choose to do fiberglass, kevlar, and or carbon, you will have to choose an epoxy that will handle the heat. Most lay-up epoxies can handle 350f but for how long? I'd recommend making one out of pounded aluminum sheet (1/8"???). Just build a hardwood form by ruffing then finishing a block using your bike as a model as well as the LSS. Just sculpt it. Then when you are finished, peen an Aluminum sheet around the form, and get someone to TIG weld any square areas and/or mounting tabs. When finished, you can either polish or spray using American SportBike frame paint. Hex | ||

the rss only makes your fuel rails hotter at low speeds and idle with the fan on. if you spend most of your time at idle you should not get the rss. BUT if you do ride your bike and not just start it in the garage to go vroom, you should be fine. | ||
| Spiderman |
This should help everyone who doesn't believe why the RSS could be bad... http://www.google.com/patents?id=sJAMAAAAEBAJ&pg=P A10&dq=erik+buell As you can see adding a RSS would cause a "air void" over the fuel rail. IE air would be pushing together from both sides not allowing air to properly flow over said fuel rail. | ||

All the boring Buell shirts available, why can't they just put this on the back of a Beefy Haynes T?  | ||

Josh: Go for it I'll buy two. Oops, Buell Motor Clothes, how about using Josh's idea, he won't charge you too much. I'll still buy two. Neil S. |
