The 12 does have 200 more ccs afterall,. My XB9R with Hals full fairing, the right frame gets HOT AS HELL. Burns the shyt outta my leg, even with jeans. I'm going to get the frame blacked out, maybe they can use high temp paint to help. the header wrap is only $60, but the black ceramic coating is almost $200 but IMO the coating looks better. I'd totally rock the wrap if I had a lightning though, for that streetfighter grungy look. |

I've got an 09 Ss, and never said it didn't get hot... for the record it certainly does. Pressing my leg tight against the frame spar with just jeans on is uncomfortable. However riding normally, in heavy traffic, on hot days, the heat from the engine and blowing from the cooling fan hasn't been an issue (and I can tell it's blowing right on my inner thigh). I'm also usually wearing a pair of textile pants over my dress pants when riding to work which blocks any heat that much more. I don't expect it to be as comfy-cozy as sitting in my truck wearing shorts with the ac blasting however.

I own a 2005 xb 12 scg there is no difference between it and the R model except cosmetics.Read the specs if you do not believe me.The temp should be the same.I have never read where the R runs hotter.Maybe I am wrong.Peace anyway. |

you are wrong. the s doesnt blow the heat right onto your inner thigh like the r. |

Just information.
I made covers both side because I had too much heat from that space. It is perfect works! Never get burn the light leg.

I put a RH scoop on and I had no more problems with a hot right thigh.
When I changed to a Micron exhaust the scoop wouldn't fit; so it was back to a hot thigh. Then I got used to it  |

Tarshi - do you have more pictures of the covers you made. How did you secure them? What material did you use? |

How would that scoop possibly cool your right thigh? |

I wrapped the pipe, then added a DEI heat shield I had left over from my stock car under the seat area. You can buy precut heat shields for these bikes, but I had some leftover material and cut my own. Those two mods were major as far as cooling my right thigh! |

Tarshi-those look good. That doesn't effect engine cooling or anything? |

I'm gonna venture to say yes, it does. if you're ever in doubt, hold your hand there while riding and feel the hot air coming out of that port. It's more than just looks, for sure. |

Hi Nuerburgringer
Not sure of the full context here, so I'll start with my thoughts from scratch.
I'll probably get hit with instant Karma from guessing that the little RH scoop that comes on an XB is to warm the fuel rail with air passed over the front cylinder. It wouldn't be to cool anything.
When you fit a RH scoop of about the same size as the LH scoop, you still get the warm air forced between the scoop and the front cylinder to the fuel rail, and you also get cool air forced to the rear cylinder.
This air cools the rear exhaust and the frame as well as the rear cylinder. The effect is noticeable. The fan turns on much less around town, turns on for less time when you stop and never on the highway. (Not so true if you have a muffler that is running lean).
I ride mainly in jeans. Without a scoop I can tell when the fan is going to come on because of the temperature of the frame heating my right thigh. With the scoop there is much less heat on the thigh.
I thought it was pretty weird when I first got the bike, but I don't notice it now. I've swapped out my Micron so I can fit a scoop again, and I will. |

One thing i am worried about it everyone else saying their fan comes on while riding. Mine has never in 5800+mi come on while the engine is on. It only turns on when i hit the red switch off. Should i be worried? I am very interested in the RSS just dont want to spend $200+ on a piece of plastic. |

Rip, That is my thought. And an ugly piece of plastic at that. I've made a lot of things, and keep thinking, how hard would it be to carve the shape out of blue foam and lay up some fiberglass? |

I guessed you must have a 2008 or 2009. Checked your profile and that's right.
Because of tighter emissions laws the fans on the later models come on at a higher temperature. This means that the bike gets hotter but the fan comes on less.
The cooling effect of the scoop on late models is more noticeable than with models up to 2007. |

Hmmm, I don't think my full fairing will allow any scoops. Guess its header wrap for me for now. |

fans on the later models come on at a higher temperature that doesn't seem like a good thing, does it? I've only had mine come in twice while riding. Both times cruising around san fran at 15mph looking at stuff. Scared the be-jesus outta me the first time. It does come on every time I turn the bike off. I wonder if you can set it to come on at lower temps? Or if that would be a good idea. |

I have the full fairing on mine too. Header wrap and the heat shield under the seat area. Trust me.

"When you fit a RH scoop of about the same size as the LH scoop... This air cools the rear exhaust and the frame as well as the rear cylinder."
Yes, and proceeds to push that extremely hot rear-cylinder air right past your RH thigh.
Primary complaint is at low speeds anyways, and at stops. Ain't gonna make a lick of difference there.
An argument could be made that a big RH scoop offers a small improvement in rear cylinder temperature, at speed. But I've never heard anybody associate that scoop with a cooler thigh. Seems like a long shot. That said, I hope you're right.
For the most part, long-term Buellies know that there's a monstrously hot air-cooled motor at their groin. Particularly in slower city-riding, its largely something that we learn to live with. Even if we find a way to make it less bad, its still gonna be pretty bad. Just my two cents. |

Hi Nuerburgringer
In under 18 months I've put 27,000 km on my 2007 XB12R. I ride every day, in central Melbourne. The January / February temperature can get up to 40 degress C, about 110 F.
While at 40 degrees C with a scoop the fan is working in stop start traffic, it is still a lot less than without.
At 25 degrees C, 80 F, the frame stays relatively cool even in stop start traffic, and the fan doesn't come on until you stop.
I'm on the committee of the Buell Riders Australia club, and probably half of the Victorian Chapter have scoops, and they will all tell you the same thing.
I can tell you that the scoop works |

This argument was presented to Abe of BMC.
The testing they conducted at speed concluded that the standard scoop was able to provide equal cylinder temps.
His concern with the RSS was that at low speed the fuel rail and throttle body would effectively be in 'dead air' that is have no air flowing over it due to both side flowing equal amounts.
The effect he said could be boiling of the fuel in the rail resulting in vapour lock - no fuel to the injectors.
This is theoretically possible and I have no doubt that in testing by BMC it could be replicated.
You would have to be very exact in the design and manufacture of the RSS for it to flow exactly the same as the left.
I have had quite a few years in Underground Coal Mines and have had much experience in airflow regulation and monitoring - it is needed to survive/breathe there.
In short they are I believe a very good thing to have. |
