Remove all hoses and valve, plug air-box nipple and custom cut block-offs for the holes in top of the valve cover out of plate aluminum. You can use one of the hose plenum thingies as a template. Underneath, there are REED valves, 2 per side 4 total. The REED valves can be used to seal your block-offs but you have to remove the #2 Philips screw from each one first as the top of the screw will interfere with a flat fit. Every single screw in my 4 REED valves broke but who cares.. you are just blocking off? Removing the PAIR system will neither help or hurt your engine performance or fuel economy. The PAIR system is simply a way for the manufacturer to get cleaner PPM (parts per million) emissions readings at the tail pipe by injecting fresh air into the exhaust on deceleration. The PAIR system does not actually add to or reduce the actual number of molecules of pollutants, it simply fluffs up what is coming out of the tail pipe. Removing the PAIR system will reduce or eliminate that popping noise you get out the tail pipe on deceleration. In my opinion, the PAIR is dead weight on the bike (mere ounces.. but?) and like you said, clutters up the otherwise cleanliness of the top of the engine. Changing spark plugs is much easier with it gone. Also, you will need shorter screws for your block-off plates.
Or.......you could use a set of my PAIRS plates I've just made available. No need to remove the screws on the reed valves as I've made blind holes on the underside for those.
I also used M6 studs and stainless steel acorn nuts (polished) for a finished look on my bike. Just a thought (or plug)
I plan to die young, as late as possible
