CB1100 and this wonderful engine...

[avsbezzy_imp]

Well, some may not agree but after taking the time to take detailed pictures of the engine, I think there was a lot of research and development done. Look at the fins, placed in the tiniest of spaces, the air flow holes between cylinders. This came to my attention as I am riding in South Florida urban traffic. Long red lights can get any bike hot, My HD softail, my Vaquero, my DRZ, the SV 650...But in this case, the heat not being too bad is dissipated rather quickly the moment you start moving. even between 2 lights. I can also feel the hot air if there is a side wind. This is with jeans and running shoes. None of my previous bikes were cooling that fast. The vaquero would burn me once the fan for the liquid cooled engine started. Kept the bike 1 month. Hated it.
That brought me to be more interested in the design of "air vents"...I think it is brilliant...please add comment, links, video, etc...
