this has probably been covered before...  has anyone used these on a 12r before and does it really cut down on the work for the electric fan to cool the rear cylinder? ps - where's the best place (cheapest  ) to buy one?? thanks aks | ||
| Buell1111 |
I got mine from American Sport Bike, great quality & easy install. I went out for a ride of about 20 miles yesterday here in FL and the fan never came on!  | ||
| Aks12r |
cheers buell1111! sound like what i'm after! just curious but which one did you get? http://www.americansportbike.com/shop/cgi-bin/cp-app.cgi?usr=51F7928188&rnd=9691 332&rrc=N&affl=&cip=&act=&aff=&pg=prod&ref=9160&cat=&catstr= or http://www.americansportbike.com/shop/cgi-bin/cp-app.cgi?usr=51F7928188&rnd=3375 017&rrc=N&affl=&cip=&act=&aff=&pg=prod&ref=9007&cat=&catstr= ....i'm trying to work out what the difference (other than material) is?? | ||
| Diablobrian |
same mold, different material. on the first one (either fiberglass or carbon) The second one is the carbon fiber copy of the stock cover. Buell111 has the carbon version of the first one. | ||
| Buell1111 |
Thanks Brian! | ||
| Aks12r |
cool - CF it is then (especially at almost half the price!) thanks guys  | ||
| Diablobrian |
The second one is not the same as the first. It will not improve the cooling of the rear cylinder over the stock piece. The first one improves the aesthetic balance of the bike and improves rear cylinder cooling. | ||
| Aks12r |
damn! that's just too expensive for me to justify the cost... don't suppose anyone's any good at making plastic moulds...? just a thought  | ||
| Chadhargis |
I know there are right side scoop advocates, and it makes sense to me that it would provide more air to the rear cylinder. What I wonder is why didn't Buell do it from the factory if it makes that big a difference. There is already a molded piece of plastic in the same location, so it's clear that area wasn't ignored. Anyone have any insight to this? | ||
| Buell1111 |
Yes, it IS a bit confusing, especially if you read the thread on the "pressurized air-boxes". Could be a total waste of time & money, but logic seems to dictate otherwise. I know here in HOT FL, it seems my fan comes on less frequently since I installed the right scoop. | ||

Buell1111, how often did your fan come on before? Did it run non-stop after warming up? Or did it come on and off depending on the situation. Mine runs non-stop on high after the bike gets warmed up, regardless of ambient temp. I'm just curious how many others experience this. | ||
| Buellshyter |
I too was skeptical. I just installed one the other day and it has made a significant difference. My fan would always come on after a few miles of running but it hasn't come on, not even once, since installation. | ||
| Diablobrian |
There seems to be lots of anecdotal evidence, we need some hard data on the actual temps of front and rear cylinders with and without the right side scoops. | ||
| Brucelee |
It is not anecdote when you install the right side scoop and the fan stops coming on. Since it is controlled by a thermo in the rear head, I think that would tell you something about head temps. which is what the fan is supposed to address. After two years, I can tell you the scoop works. | ||
| Diablobrian |
it is anecdotal when scientific method is not used to compare the results. Anecdotal means it has been related through subjective stories, not hard data. | ||
| Stretchman |
I don't know about anecdotal, but I have heard that the uly could really benefit from one. They say the leg starts cooking on the right side because of the pipes. I have only heard this from the people that have rode them. Don't know if it's true or not. Hopefully someone is listening and will research. | ||
| Brucelee |
"I have only heard this from the people that have rode them" Don't listen to them, what do they know? They only ride the bike. Wait for the lab for all the answers. | ||

Update on the right side scoop - I went into the city, yesterday. It was typical stop and go city traffic and the fan finally did come on but what the fan did do, which it NEVER has before, was turn off after a few miles. My bike used to be like Az_M2's...the fan would come on and stay on. One other thing I did notice was when the motor got hot and the fan came on the hard shifting and engine pinging started. As soon as the engine cooled these problems disappeared. I would have to say the problems are heat related....anecdotally, of course  | ||

Man looks nice the cost is price. | ||
| Midknyte |
I only wonder about the shrouding effect it might have on the front cylinder. | ||
| Diablobrian |
Midknyte, that's not important. Listen to the people that have ridden with them. All that matters is the temp sensor in the rear head. Scientific methodology is crap! | ||
| Diablobrian |
Stretch, Wouldn't wrapping the pipes, or maybe jet-hot coating the pipes be a better solution for heat from the pipes? | ||
| Chadhargis |
It makes complete sense to have an additional scoop feeding the rear cylinder, but I'd love to hear from someone with an inside contact at the factory as to why it's not there in the first place. Since there is a right side scoop (it's small, but it's there), it's clear that the area wasn't ignored. So, why no scoop on the right side? There HAS to be a reason. I've not ridden my Ulysses in really high heat yet. About 87 degrees is the hottest I've ridden and that was two up. Yes, the fan ran. And no, it didn't shut off until after I shut the engine off. However, I didn't notice any pinging or other performance degradation. Seemed to ride fine. So unless someone can tell me why the factory didn't put a scoop there (seriously doubt it was due to cost cutting) or I start having heat issues, I'm going to stay with the stock setup. | ||

Stretch, Wouldn't wrapping the pipes, or maybe jet-hot coating the pipes be a better solution for heat from the pipes? Don't know. Don't have a Uly, and never had a heat issue on my XB, even tho I am in SOuth Fl. If the scoops work, then great. Me, I am still trying to decide on a seat. I have heard from people that ride them that the bike gets hot for the rider. Even heard it from a dealer who rode one home on a test. But I can't say where it's coming from or why for certain. Myself, that is. Stretch | ||

Anyone know if the scoop will work with the Force Exhaust system? | ||

Since there is a right side scoop (it's small, but it's there), it's clear that the area wasn't ignored. So, why no scoop on the right side? There HAS to be a reason. From what I've read on this site, most folks DO NOT have a problem with their fan running all the time like I do. Most folks have reported that the fan comes on and then shuts off after a while. Based on that, I could see the factory not putting a scoop on the right side because the bike is adequately cooling itself and there are asthetics to consider (why cover up the motor, pushrods, etc. if you don't have to?). My situation however does not seem typical. My fan runs all the time, regardless of ambient temp (even running in the 30's and 40's). I've had the dealer check out the bike and "the fan operation is normal". That said, wouldn't it make sense for me to install a right side air scoop, considering that folks are reporting positive results? Also, I have very little pinging. Bike seems to run fine, even when hot. | ||
| Ferret_bueller |
does anyone make a right side scoop that matches the left? i know the pipe is in the way on the inside, but the outside circumference. or maybe new left and right that match each other in size? | ||
| Monorad |
my fan used to come on all the time. i put on the right side scoop last august, during mid-summer heat and noticed the difference immediately. anecdotally, the fan came on at least 80% less. if you don't ride in really hot conditions, you probably don't need it. it does look cool and balance the look of the bike from the front. seperately, wrapping the pipes doesn't address this particular issue, but it does make it hurt less when your leg hits the pipe and it looks cool as well. it also, anecdotally, keeps the heat in the pipe, which speeds up exhaust flow and increases horsepower by EXACTLY 0.025% (i measured!) lol | ||

"All that matters is the temp sensor in the rear head. Scientific methodology is crap!" No, the only thing that is crap is your limited thinking! | ||
| Brucelee |
"So unless someone can tell me why the factory didn't put a scoop there" we are still trying to figure out why the factory won't add 20 HP to the engine or why the RR clutches self-destruct, or why the clutch cables are a tad crappy, Wait a minute, I thought the factory never made a mistake????????? |
