For those of you with the RSS, does it cool the right side frame? Changing oil weights took care of cooling the engine and stopped the fan from running for me, but the right side frame still gets blistering hot on my Uly and I started to wonder if the RSS would fix that? | ||

Well I don't seem to get hot air blasting up from under the seat like I used to as the fan isn't going all the time. I don't know how it would go in stop start city riding in hot weather though. As for the frame it self, I can't say as I don't think I have ever touched it? | ||
| Jmhinkle |
Mine is blistering hot thru jeans. If I would touch it barehanded, which I have not, my skin would adhere to it. | ||
| Mortarmanmike120 |
I don't know man, that doesn't sound right. Hundred degree weather, hard riding, stop and go, mine never gets near that hot. Maybe Uly's are different but that sounds bad. Is it the frame or the underseat rail? | ||
| Jmhinkle |
The rear part of the right side frame where your leg rest against it. I know of a couple other Buells that do it too. One is a CityX. I just assumed they were all that way because of the thinness of the right side and closeness of the rear head too it. | ||

It works... N x | ||

I think you can probably help the problem, but I think it may take a little more than just the RSS. If you get the RSS and ceramic coat your header I would think it will help a ton. | ||
| Old_man |
The exhaust pipe is the culprit. I heat wrapped mine by the frame only and then covered it with a shield. | ||
| Al_lighton |
The silver ceramic coating drops the header temperature about 175F. Considering that the primary heat transfer mechanism to the frame is radiation, and that radiation transfer is proportional to (Tsource^4-Tsink^4), and that the silver has half the emissivity of the uncoated pipe, you can get some good temp reduction on the frame this way.

Ceramic Coated satin Black here. HUGE Difference in Heat Radiated to Leg. N x | ||
| Cycleaddict |
has anyone tried coating the inside of the exh. pipe ? (i like the golden/blue stainless) | ||
| Captain_nartman |
errr Ceramic Coating Does The Inside Also. N x | ||
| Terribletim |
I have to second the hot right side of frame situation. My 'Bolt gets a bit warm on the inside of my thigh as well, not blistering hot, but warm none the less. | ||
| Cycleaddict |
how "well" does coating the inside of the ex. pipe work ? same/similiar results ? anybody tried it ? | ||
| Captain_nartman |
As said.. ya CANNOT Ceramic Coat External without Doin it Internal.. they Dip it Unless I'm Mistaken.. but yeah.. IN n OUT is done. N x | ||

When i had the engine rotated to get the pipes off to get them ceramic coated i took a adhesive back heat barrier and put it on the inside of my fuel rail and i have to say it does make a difference.The other day it was 81 degrees out and when i got home i checked the temp on my right side fuel rail and it was 95 degrees. I bought the stuff from Jegs which is a car performance catalog. I also put the RSS scoop on. (Message edited by tiburondriver47 on April 03, 2007) | ||

You can absolutely do just the outside. We get mufflers done that way all the time. They seal up the ends. | ||

What is a "fuel rail"? | ||
| Icon12r |
possibly the frame/tank? | ||
| Terribletim |
My only dilemma is the whole "rotating the engine" thing. Without a lift or nifty frame stands, I'm not sure I want to dive into that big an operation. I would like to pull my pipes of and wrap them, even more now that I have the full body kit. But it's so close to riding season, do I really want to start taking the bike apart now? Between THIS and my family eating up all my time, weekends go by quick! Wonder if I can get my boss to let me do it at the office. . .  I totally agree with the idea of the heat shield from Jegs. We use it on the racecar, good stuff! A bit spendy though. | ||
| Molly_hatchet |
i had a friend that coated the inside of the pipes on his hog...didnt work to well..it all blew out in like a week....sounded like a good idea...but wasnt ...they make heat pads for under seat exhausts u might wanna try something like that...or just have the pipe coated like the others have suggested. | ||

Fuel rail/frame/gas tank. | ||

Odie's heat shields work wonders for that rear cylinder heat issue. My right leg rarely, if ever bothers me. www.specialops-online.com Sam | ||

I'll throw this out just for thought. What if the RSS does a good job of cooling the temperature switch which starts/stops the fan? The observed effect would be the same. The fan runs less often. Only one problem, the switch may be cooled and the rear cylinder is still getting hotter than designed. Where is the fan temp switch located on the Buells? Dave | ||

Hey, Jmhinkle, on another note, let us know how the new oil works out for you. I believe you are running the 5W40. I am taking my 'bolt in for 5k service soon so they'll undoubtedly use 20W50. I won't waste good oil, so I will probably switch to Rotella Syn at the next oil change. I am curious to see what your UAO says about it. The one time I used 5W40 I noticed the bike running cooler to as evidenced by fan not coming on as much. I never did a UAO though. | ||
| Tiburondriver47 |
I use a laser heat gage when i get home after some spirited riding and the rear temps are very close to the front temps.I have the RSS scoop and my pipes are ceramic coated. I also have the oldie heat blanket under my air box and seat and they do help with keeping the heat off your rump. My fan rarely comes on. | ||
| Watrousmark |
Wpadave the sensor is right in the center of the head. The next time the airbox is off look straight down. | ||

Insulative and reflective heat barrier affixed to inboard surface of frame/fuel tank seems like a very good idea. Not much space there, but even a thin layer would seem to do a lot of good on a hot Summer day. Hot Fuel is not desirable. (Message edited by blake on April 06, 2007) | ||

Johnny, I'm having wonderful results with the Rotella Syn. See post here: http://www.badweatherbikers.com/cgibin/discus/show .cgi?tpc=37&post=860421#POST860421 It hasn't used any oil yet since I did the change 600 miles ago. Temps are ranging from low 40's at night to low 80's in the day here in the desert right now. It has also been much warmer since removing the 20w-50. The fan was running all the time on any 20w-50 and has barely ran since changing. I truly believe the cooling issues are oil related and not airflow related. I will do the UOA when it's time to see how it held up. When money allows, I will buy the RSS strictly for looks. I will most likely get the header coated first to cool the right leg and frame though. | ||
| Sneth |
Jmhinkle, which exact blend of Oil are you running? I could figure it out from linked post... Rotella Synthetic something.... | ||
| Jmhinkle |
Rotella Synthetic 5w-40 in the Blue bottle from Wally World. | ||

Jmhinkle- I installed a RSS before adding ceramic coated header and it made a dramatic difference with how often the fan ran and how long as well. I changed nothing else so it is a good control set for your consideration. It sees to me that the factory left side scoop (LSS) serves its purpose but might only cool the left side of the rear cylinder. The ceramic coated header is a great compliment. I have posted recently with my concern that my fan doesn't come on at all lately and the more I read the more I'm convinced that it is because the whole thing is running that much cooler. I do live in a very temperate climate, where the mean temperature is 55 F. It does "bake" inland, where I ride in the summer so, I'll have more to say about the issue in the coming months. | ||

Terribletim- rotating the engine down to do exhaust mod's is really simple. It's a half-day chore at worst. Al from American Sport Bike was kind enough to forward instructions on how to do it and it was spot-on. Don't be hesitant to get to know the bike. You won't be taking anything apart that you can't get back together again - easily. If you've got a floor jack and a swing-arm stand you're half way there. |
