Hey Tom,
Sweet, I would love to check out your bike.

I'd agree with Froggy about the fan coming on less when the bike is run in. Fuel consumption gets better, engine is freer. My experience is with an '07 model that has the fan set to cut in at a lower temperature. '09 fan turns on less while riding so the difference after being run in may be a bit less obvious on the later model.
The only buell burp I know of comes out of sales people.
If I open the throttle with a whack I can almost stall mine. It's not the best way to get going on just about any machine.
I need to feed my throttle a bit. I can open it fast but not instantaneously. |

FWIW, I think the RSS (CF or FG) is just a good idea. I figure if anything it can't hurt. Plus, I like what American Sport Bike says about adding symmetry to the bike. I'm with the group that doesn't care about the "extra" heat coming off. Wearing PPE, you can't feel it anyway.
I'm with you, Dad4, as much as I *love* my XT, the only issue I had were the lollipop mirrors. The fact that they are known as that may be part of it. The Aprilia's are much more stylish (and, I think, functional). Also, very easy to install (once I figured out how to get the stock mirrors off - Duh).
Just at 2600 miles now, and it's only getting better.

Actually it can. Without opening the can of worms, this was in Fuell magazine a year ago

Q Abe, what can you tell us about the “right side air scoop” on
the XBs? I’ve seen people fit larger ones (near mirror images
of the left side) in an attempt to increase cooling capacity.
It seems the smaller one will allow for an increased air
velocity and potentially more cooling. What’s the deal?

A The intent of the right side air scoop is to get better airflow over
the fuel rail when the fan is on (at low speed). Getting proper
airflow to the fuel rail is important in order to prevent vapor-lock
during extended idle or parade duty in hot ambient temperatures.
It turns out that if this scoop has too big of an opening, the airflow
is not directed to the fuel rail as effectively. In our testing, a right
side air scoop created as a mirror image of the left hurt fuel rail
temperatures at idle.
The left side air scoop was shaped to direct air to the rear cylinder
and is very effective at doing that. During our high-speed, hot-
ambient testing, the front and rear spark-plug base temperatures
are virtually identical, whereas on the old tube-twin bikes there was
a 100 Degree Fahrenheit difference (rear running hotter).

I believe that the inside of the scoop directs the air well behind the fuel rail.
There is a gap between these scoops and the front head which serves the same function as the little scoop that directs the air to the fuel rail. Because of this I do not believe that it has a detrimental effect on the airflow to the fuel rail. There are so many scoops around that problems like these if they were occurring would result in big threads for actual problems instead of for theoretical problems.
The RH scoop probably doesn't make much difference to the rear cylinder temperature but I find that it does cool the Frame and reduces the frequency and duration of Fan operation on my 2007 Firebolt. |
