@night cub There were carbureted [CB]s overseas but you are accurate in the US/CDN did not receive those F18/F20 motors: http://www.cb7tuner.com/vbb/showthread.php?t=145202

There is a thread from the [CB] forum with an image of the F20 carb'd motor. That is why we can classify US/CDN as [CB7/CB9]. The 3rd digit indicates the motor type.

@reg1992 love the honda
