2006 CBF 500 Pair valve removal
 

Hi, just bought a low kilometer CBF 500 for my wife. Ive heard good things about removing the pair valve/ air injection.
Can anyone point me in the right directions of the best way of doing it? Blocking it or complete removal?
Any help would be awesome.

Can't help with the how but interested in the why. How will it change anything? Its just adding fresh air to the exhaust. If it changes what the sensor downstream sees you'll just reduce the range.

The reason people do this is to make the bike lighter and easier to work on. It doesn't make them run any better usually.

I don't know this model, but it usually means blocking the holes at the head and then blocking off any vacuum pipes from the carb to the valve also.

On the CB500F its a control valve on the relay tray and two reed valves on the corners of the valve cover, smaller than a matchbox and not much heavier.By the time you got under the tank and that far I wouldn't view them as any huge challenge. Sealing the corners of the valve cover looks the hardest bit. i was thinking the CBF would be similar.

Now on the Bonneville the tubes stopped you getting at the spark plugs so worth removing, but easy to seal with drainplug style bolts and washers.
