I am slowly trying to get some more umph ! out of my 06 Bonnie and like many that are new to this wonderful bike find my self spending countless hours on the net trying to learn my way around my bike.

I have noticed on New Bonneville that you can purchase a "Crank Case Breather" and that it is included with the NARK system.
Could anyone explain the benefits of this tiny little breather and where and how it basically works.

On a stock bike, the crankcase is vented to the airbox. Remove the airbox and you need to put some sort of filter on the vent tube to keep crap out of your crankcase.

What Joe said, but I will add that for various reasons one can get some oil out of the crankcase vent. With the airbox in place when this happens, one will find the oil pooling in the airbox or draining out of the airbox drain--if it is not stopped up. Without the airbox, one can get some oil out of the small filter when this happens, so depending on where you locate the filter you can have an oil mess. Some have put an oil catch can in conjunction with the crankcase vent filter.
