Air Cleaning:

The F3 and K8 both received an air cleaner for the crankcase breather . This consisted of a plastic housing with a filter element. Crankcase gasses were routed to the breather through its air cleaner and then back to the airbox (intake air cleaner housing). The breather is located behind the left sidecover, underneath the rectifier.
