buell factory right side scoop

[Subarubrat]

I have the CF L + R ones and cooling has been excellent. I *think* I recall reading in the Fuell magazine (the old Buell brand mag) that the left and right were different for a reason but I don't recall what model it was discussing. Anyway, the big CF ones on both sides have worked great for me.

Got pics?

Here you go, sir.

It was in the "Ask Abe" section of Fuell®, Fall 2007. As explained by Abe Askenazi - Director of Analysis, Test, and Engineering Process at Buell:

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?
– Ryan, Lightning® XB12Scg owner

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).

Good stuff. FYI - Abe is now the CTO at Zero Motorcycles.

Great reference! My rear CHT is lower with the bigger CF scoop on, should I ever have an issue with vapor lock I can fire sleeve the rail, if I ever start doing allot of parades in Vegas.

Is there an archive of the Fuell mags online? I have looked but not found them.

I too would love to find these mags online.
