Received my scoop from Rob Crins and installed it last night. Fit and finish is excellent. I took it for a ride today and the fan did not cycle on once. Previously it would run constantly even in mid-60 degree weather with synthetic fluids. Well worth the price. Thanks Rob. | ||

Please post a picture! Is there a downside with this upgrade? Too much cooling? | ||
| Stewadi |
Good to hear. Just waiting for Rob to ship mine. Can't wait to get it!! | ||
| Cyclonedon |
what is the price of this scoop? and where do I order one from? | ||
| Terrible1one3 |
What about Right side heat? Any difference? I want one, but 200+ I want more than just less fan noise. | ||

I rode my ULY to Leesburg (FL) Bikefest today. High 80's with lots of stop and go traffic. My fan only came on once while riding. I have a fair lot of mods on my ULY (see profile) but I consider the RSS the #1. Frank | ||

" I want one, but 200+ I want more than just less fan noise." They sell PVC pipe at home depot  It would probably melt though... | ||
| Electraglider_1997 |
That guy would sell a bunch of them if he would just sell for a reasonable price. $100 would be reasonable. Why gouge? Sell 100 for $200 each and he gets $20,000 or drop the price to $100 and get orders for 1000 and he gets $100,000. We are not just talking ULYs but all XB's. | ||

Doesn anyone have a connection with someone at Buell so that they could find out why these scoops are not just part of the bike from the factory. I have read several threads on this board. Everyone that has the scoop loves it and swears the fans run less and bikes are cooler. Others question if this was such an easy idea, why didn't Buell do it in the first place. Now that the bike has been out for a few years, this would have been an easy fix / enhancement but still nothing from the factory. I would love to see Buell respond to whether adding these scoops is a good idea. Do they monitor this board? | ||

From what I was told at Homecoming last year was it isn't needed. I was also told by a Buell Engineer that you do NOT want one on in very hot weather. I believe it actually disrupts the air flow. I know it sounds strange, but I would think they're more "in tune" than us. And if it was needed, they would do it at the factory. | ||
| Rocketsprink |
Yes. I know for a fact that Buell employees read this board. I'll be at one of the engineers houses later today helping put his Race Bike back together. And I suspect, as usual, he will tell me nothing. I don't ask. He doesn't tell. Buell has this strange thing about letting out future ideas and firing. But the question was asked last year at the factory about the scoop and Buell says it isn't needed. | ||

I am not going go over the RSS positives again but don't throw the Buell engineering expertise out there again either. Jeez, how about side stands?? ULY's, early XB's, S2's Tuber speedo sensors. ULY horns. ULY BAS's........... Frank | ||
| Rocketsprink |
To be perfectly honest I have a RSS and have noticed NO difference in the running of the fan. I purchased it just to see for myself. XB's have been around since 03 and they still don't have a large RSS. I would think that this fan "problem" would have surfaced before the Uly came out. And sorry, I'll take their word over yours. Not trying to be a dick either. | ||
| Rocketsprink |
Sorry, never heard of the Uly horn issue, although my 04 12S had a horn recall. | ||
| Ftd |
Rocketsprink, you are the only person I have heard of who has had no effect on fan operation after installing a RSS (I am only speaking of ULYs). ULY horns come installed in a location which results in a banging sound as the horn bounces off the wind screen. Why aren't these things discovered and fixed when long term testing is done? | ||
| Marks3tbillet |
Thanks for the info on the horn bouncing off the wind screen Ftd. I have ridden three Ulys and was trying to figure out what the screen was bouncing off of. I could always hear the noise and I wear earplugs. Is there a mod to stop this noise? Mark | ||

+1 on the Uly stuff. Side stands, horns, BAS, wiring harness, chaffed plug wires, pinched ECM wires under the seat, swimming dunlops, lame azz headlights, rear cyl heating up the fuel in frame...you get the point. Engineering, mass production politics, profit. It is all a trade off. I still love the Uly more than any other bike I have ever owned. On my Uly, I have addressed all of the issues on my own, and with the help from other Buellers on this board. The RSS is probably one of the most functional mods for the Uly for anyone that spends any time in traffic. 250 buckaroonies for something that makes this much difference is worth it for me. Buell is listening. They can not stamp out a $99.00 plastic RSS like the Left side scoop as it would surely melt being so close to the heat of the exhaust. Rcrins uses special laminates and paint to withstand the heat. In the end, if Buell does not address these issues, rest assured the aftermarket vendors will. | ||

Let's clear something up about the RSS. It is a cosmetic mod. It's something owners do because they don't like the sound of the fan running, or they don't like the look of the lopsided scoop. The bike does not need it to prevent overheating. That's why Buell does not add it from the factory. And they've said as much on numerous occasions. I'm all for folks modding their bikes as they see fit, whatever. I just think it's a good idea to remember that this is not a functional issue, it's a cosmetic one. | ||

"The RSS is probably one of the most functional mods for the Uly for anyone that spends any time in traffic." How does that work? I thought you had to be moving for a scoop to direct airflow.  | ||

I think there are a few reasons why Buell doesn't come out with a RSS as a standard item on their motorcycles. 1. They believe it isn't needed. (Maybe they think the fan is extremely innovative and does it's job well) 2. They would have to rework the sensor on the fan to make it fucnction properly. I think part of the dilemma Buell sees with the right side scoop is the sensor for the fan is in such an area where a RSS abstructs the temperature measured in that location. If the wind blows the heat away from the sensor but the motor is still producing the heat and the fan doesn't kick on Buell might think that could adversely effect engine performance and overheating problems. 3. It's more high price stuff for them to make. And adding it would be an admittance of an obviously very good piece of engineering they missed. I think the reason for the absense of the RSS is a collaboration of maybe all three if the temp sensor thing makes sense. Personally I do not like the Fan, I don't see how blowing hot air around inside a fairly closed area could work out to be so beneficial. But then again if it does do something good I don't mind it. I think a RSS and the absence of the fan would allow for better airflow for the bike when it is moving. But at a standstill or in traffic it might be prone to overheating more but hey, that's a price to pay with an air cooled V-Twin hugged inside the biggest damn frame a two wheeled machine has ever had. I want to get a RSS for maybe 100 bucks. Will never pay 200 for one. If it works out nice I would take the fan out and rely on this lovely thing called air to cool my bike. So I would have one of the few Air Oil and brains cooled motorcycles. (Message edited by terrible1one3 on April 28, 2007) | ||

You can search the anonymous posts on the RSS subject and you will find out exactly why there is no RSS from the factory. They have been very candid about this subject. If I remember correctly, they said that according to their own testing, the RSS does not aid cooling at all. That is why they decided not to add it to the design. FYI - They didn't add magnets to the fuel lines or vortex generators to the intake for improved fuel economy either.  | ||
| Florida_lime |
No fuel line magnets or intake vortex generators ??? Darn Buell antiquated technology.  | ||

I love my Buell and my past Buells. I do not think you do bad by discussing an obvious issue as Heat on the Ulysses platform. I know first hand it runs far more often than on a Firebolt or Lightning as I have owned one of each and the Ulysses is a screamer when it comes to rear fan so there is obviously more heat. Testing is by no way a measure that there is no problem as I'm sure there was some amount of testing on the Ulysses before release and we have seen Changes, Airbox, TPS, sidestand, OEM Tire and seat changes just to name a few. Its ok to talk about this or it will never get fixed. Wasn't the left scoop originally for engine intake and not a rear jug duct anyway? | ||
| Lowflyer |
Yep, they did make improvements on the Uly, but they still seem to have overlooked the "obvious" cooling "problem" that is solved for some folks by a $200+ piece of milk jug. It is weird that they would pass up the opportunity to put a RSS on in 5 model years of XBs if it was truly a functional improvement.  | ||
| Brad1445 |
I don't think it was a problem until the longer frame arrived. | ||

How does that work? I thought you had to be moving for a scoop to direct airflow. When the Uly is stopped in traffic the fan will come on. With the factory small scoop device in place, the Uly fan will draw preheated air from the area surrounding the hot headers. Because the amount of air it draws is moving slow, it gets even hotter as the slow moving air absorbs heat from the factory scoop which is also preheated by the headers. With the large RSS, the air that the fan draws in is forward and away from the headers, and also cooler.The larger volume of air, drawn by the fan is also less likely to absorb resident head from the scoop. Benifits: Cooler running engine. Longer fan life. Kick azz looks. Drawbacks: 250 buckaroonies or Increased manufacturing cost from the MoCo. Look, I am sure the Uly would be fine with out the RSS. If I lived in the north where the weather is cooler and the traffic less dense, I probably would not have bought one so easily. But here, in the hell hot republic of south florida where traffic never ends, it does indeed make a difference in the cooling of the engine and the run time of the fan. | ||

All this about the right side air scoop and not once have I seen a post where a Uly has overheated, I agree it's not a functional mode but a cosmetic one. So lets quit talking about it already. Some think it's a good idea and others would rather apply the 200 dollars to buying fuel. If you like it get it. I don't even notice the fan much so I don't see it as a problem. I'm in the other camp. I think the fan is there to regulate temps at the optimal temp for the operation of the engine. If the fan doesnt come on, the engine is not reaching proper temps. I'ts running too cool most of the time. Every vehicle runs best between certain temps. I think the fan keeps the temps in that range. | ||

I'll toss in my 2-cents worth. I'm thinking that the [larger] trunk box of the Uly creates an eddy behind the fan that lessens the airflow through the pin-wheeling [non-operting] fan. The fan has to run more often, and in more operating conditions to overcome this. The trunk box may also help to amplify the sound of the fan, as well. The luggage also probably complicates the in-motion airflow to the rear cylinder. Motorcycles are slightly less aerodynamic than a curveball! Any attempt of flow analysis aft of the handlebars should also be augmented with a fair bit of voodoo, just to cover the bases. If someone has their original RSS [the "non scoop"], maybe they can offer it up for a bit of a science experiment....I'd like to see if the addition of an NACA flush intake, cut into the side of the scoop, can help the airflow to the rear cylinder. I don't hold out much promise for this, because I think the airflow across the side of the bike, any bike for that matter, is just too turbulent and dirty for an NACA scoop to work. ...what's an NACA intake? http://en.wikipedia.org/wiki/NACA_duct An NACA intake will leave the trailing airflow cleaner than an aftermarket RSS, and less likely to stall out the suction airflow that Anonymous was talking about. I give the NACA scoop about a 5% chance of working, but given our eager willingness to strap all sort of clap-trap to our bikes, I'm going to give it a 75% chance that somebody tries it! Also, could somebody direct me to the "frame heat gets the fuel hot" thread? This should not be perceived as an issue. | ||

"If the fan doesnt come on, the engine is not reaching proper temps. I'ts running too cool most of the time" That is a serious misconception you have there. If the fan is on, it is because the temp sensor has determined the engine is too hot. That means it is beyond the proper temp. There is a range it should be in, but it is below the level where the fan kicks on. The fan will run until it the sensor is back down to a temp that allows the oil to have room to heat and cool properly which is the problem with 50wt. Once it gets that hot, it no longer flows well enough to release heat and properly cool the engine. The oil itself becomes heatsoaked and while 50wt generally will withstand the conditions, it is now completely relying on the fan to do the cooling job. |
