I can't imagine it'll be significantly hotter than it already gets; the air off the fan blows across the shock whether the baffle is there or not. In fact, there may be some improvement by having the remote reservoir isolated from the hot air by the new baffle. | ||

I'm sure it'll be fine. If anything, it'll be *cooler* with air actually *moving* past it, instead of sorta stagnating there like I'm sure it did when it filled the underseat area. Buell doesn't make upgrades lightly. They do their research. | ||

Does anyone have any idea what the ECM reflash actually does? ...is it just a recalibration of the fan on/off temps and speeds, or does it actually change the fuel mapping? I'm really looking forward to putting this on my Uly, and need the latest flash regardless - just wondering if anyone knows what this specific calibration entails. | ||

Here's the quote (on the page for the Rider Comfort Kit under accessories) on Buell.com: Although not required, to maximize the benefit from the rider comfort kit, a new electronic fuel injection calibration is available for installation. See your local dealer for detailed instructions. Note: The new calibration uses a combined vehicle speed and engine temperature based strategy to optimize the cooling effects of the motorcycle's fan while minimizing the fan's run time. It may change the fuel mapping, but the main emphasis seems to be that it's changing how the fan's controlled. Right now I believe it's strictly based on cylinder head temperature and whether the engine is on or off. This says the new control scheme will also consider the bike's speed as well. | ||

Remove everything you can see, except the titanium-color tailsection rails, and the shock itself (the reservoir has to be unbolted - but not unhooked - for the install). If you can't look down thru the rails and see the tire/hugger...you still have stuff to take out. Uh-oh... does that mean you'll have to do all that to replace the fan, or shock, or O2 sensor, with the shroud in place? | ||

My C kit is on order. I hope this helps the nuisance issues a good bit. IMHO, the Uly could be a wonder bike if it weren't for the excessive heat and vibration. | ||

Heat I can identify with but vibration? I just don't have the vibes in my 08XT that I hear some complain about. This bike is smoother at almost all speeds except idle that my 04 and 06 Sportster was. | ||

With 22k on my original fan, I am wondering if in the process of installing the C kit that it would be a good time to install a fresh fan? I've not installed a new fan so I don't know all the installation details but it seems like something to consider. I am also very hopeful that a reflash of the ECM may better modulate the fan operation. I have advocated this approach in the past and I am pumped that Buell has developed a released product. Anyway, I am off to order my C kit for my 06. | ||

Hunh. I dunno how much a fan shroud or reducing the fan's run time will help with right leg heat. My right leg gets painfully hot when the fan's OFF, not when it's on. The heat goes away as soon as the fan activates. | ||
| Hughlysses |
Sanchez- that's easy to fix without the comfort kit. Glue a piece of weatherstripping to the bottom edge of the seat along that side, or seal off the opening in the top of the frame above the rear cylinder head with Thermotec or aluminum HVAC tape. What happens is the left side scoop is "pressurizing" the area inside the frame as the bike is moving. Some of the heated air under pressure comes out of that opening above the rear cylinder head and blows out through the gap between the bottom of the seat and the frame on that side roasting your leg. Once the fan kicks on, the fan pulls a vacuum on the area inside the frame, so that the hot air is drawn out the fan rather than being forced out onto your leg. Yea, it is hard to see how the kit could have any effect on that. I'm wondering about the updated ECM program- maybe it runs the fan at low speed when the bike is moving as soon as the engine starts to get warm? That might help with the right leg heat. | ||
| Tootal |
If the right side scoop is installed then that pressure will equalize and go down central and not on your leg. That's just an assumption though and needs to be proven. I ordered mine, we'll see. | ||
| Hughlysses |
Tootal- you may be on to something there. I've got one on order too. | ||
| Petereid |
Mines on order too.......Just to note, in Canada they sell for $159 | ||

I had an aftermarket RSS on my Uly for a week or so. I installed the RSS and honest to god, the fan never ran again until I took it off. Freeways...around town..it was kind of spooky, lack of fan noise made me nervous, so I took it off. I wanted to mention that on the freeway, the right side scoop caused air flow thru the frame to change. The right side of the frame was warm but not hot (for a change!) and the left side of the frame was also warm (used to be cool when running). Leads me to believe the Tootal is on track believing that the air flow will equalize and run down the center of the frame and (hopefully) out the fan/shock opening. Can't wait to try out one of "Buell authorized" RSS units to see how it works. | ||

My fan failed so this looks like a good time to install the comfort kit but I have a couple of questions. It looks as if the right side scoop is included in the kit, correct? Also the previous owner installed a race ecm so that can't be reflashed (I guess). If I reinstall the stock ecm will it run okay with my drummer exhaust? | ||
| Growl |
right scoop is included. stock ecm will be okay but better if an appropriate fuel map is flashed into it. probably I would run the race ecm until some people report their experience with the "comfort" ecm revisions then decide. (Message edited by growl on August 02, 2009) | ||
| Azdaniel |
Thanks-I'll order the kit and fan next week. The race ecm is Buell's unit, wonder if there is an updated map for it (pn 32629-03Y). | ||

After reading all the recent stories about the new "Comfort kit" I had to take the Uly out for a ride just to get reacquainted, as it has been 3 months since I have ridden either of my bikes. We spent almost two hours two up, in hell hot Miami traffic, mostly US1 stop and go traffic. My fan never came on, until I arrived at home and turned the engine off. It was then that I realized that I already have a "comfort kit". I have had it for over two years.  What happened to all the naysayers that blasted those of us that purchased the original RSS when they came out. Seems to me that the mother ship has found yet another way to profit from it's loyal customers by selling them what should have came with the bike to start with. | ||

The original RSS was in no way comparable to the Buell system. | ||
| Hughlysses |
Not to mention the cheapest RSS costs about 2X what the Buell package costs... | ||
| Froggy |
And those cheap ass RSS's need to be painted to match the bike, or spend through the nose for the carbon one. | ||

Treadmarks, 2 hours in Miami in August and no fan! I would be happy if the C-kit is half that good but I am hoping for something equal to that. I bet some folks will buy the kit but only install the RSS just to see if the rest of the kit is necessary. I am thinking it is going to take the re-flash to really make a difference though. Once the fan does come on, it runs way too long in my opinion. It should be smart and cycle in response to changing conditions. The next couple weeks are going to be very cool see how the C-kit is examined and tested and how the results come out. We should be working on baselines pre-kit. I already know within one half block when my fan comes on. It will be an easy test for me. | ||

I'm looking forward more to the fan duct that goes under the seat. As far as establishing a baseline, I'm not sure my fan run time has "hit bottom" yet. I have ~19,800 miles on my 07 so far and there has been a noticeable decrease in fan operation since 10,000 miles. Today it was ~80-85 degrees F and cloudy. I rode a good 7 or 8 miles in stop and go traffic before the fan came on for the first time. I stopped to get a photo about 45 minutes later (see "New Riding Game" on the Quick Board) and stayed long enough for the fan to cut off. I got back on the bike and headed back the way I'd come at 60-65 MPH for a good 20 miles before the low fuel light came on. I pulled over after a couple of miles to refuel and the fan had still not come on. My bike's pretty much gotten to the point that if the temp's below 90 degrees F and I maintain the speed between 35 and 65 MPH, the fan won't come on until I slow down or stop. It would be really nice to find out the RCK and ECM update improve significantly on this. (Message edited by Hughlysses on August 02, 2009) | ||

The original RSS was in no way comparable to the Buell system. I will have to agree with that statement, sort of. They both catch air for the rear cylinder. The original RSS however looks like it belongs on the bike, and is a very good match for the Left side scoop.     The factory version looks more like an after thought:  Kind of reminds me of this design, just a little more refined:  Now if by system, you are referring to the interactions of the various components like the heat shield (not necessary if you have ceramic coated headers) and shock preheater shroud assembly as shown here:  personally I prefer Odie's blanket tucked under the ecm and bas to protect the electronics and keep the seat cool. If you are referring to the speed sensitive software interaction then you may have a valid point. Using pre 08 ECMs, I use different maps achieve different goals. Power maps, economy maps, heck I even have a 2 up 65 mpg map from Al at American Sport Bike that I still use on trips. I'm not looking to provoke anyone here but I am saying just cause the mothership came out with a "comfort kit" 4 years late, that doesn't mean it is any better than the products our fellow members and site sponsors provided in our time of need. | ||

Tread, I get it - others were first on the scene. But you're talking about a piece-meal approach to solve the heat issue. Four years late, maybe, but its a sys., designed by the factory that addresses a specific problem. I say, good for Buell - its nice to see a manufacturer involved in the ongoing development process of their machines. Just my 2cents. . | ||
| Treadmarks |
You're right JB. It is good to see a manufacturer use customer feedback to improve their products. And four years is nothing really, most other manufacturers never act on customer's feedback. 2 cents well taken.  | ||
| Electraglider_1997 |
Treadmarks, You can measure your oil at the dipstick. How hot does it get with that RSS when it is up to temp? | ||
| Odie |
Does anybody have a Rob Crins RSS they want to sell after they get the comfort kit???!?!?!? |
