You can buy block off plates for around 30 dollars. Easier than making them.
Swingarm travel isn't an issue and doesn't interfere with the sensor at all. Where the O2 sensor is mounted, the swingarm doesn't travel up and down.
The mounting point is in the bend of my pipe as well. I chose the spot and drilled it myself with a step bit. Then took it to a welding shop and had the bung tig welded in.
I can tell you the work up front is a bit of a pain, but it is well worth it. Bike runs fantastic. I have a full akrapovic system and had a bit of surging at 2-3000 rpm. That is totally gone. The autotune makes adjustments fast too.
Oh and spray from back wheel is negligent. I don't ride in the rain, but if I did I would have mounted it in the same place. There aren't too many more places to mount it. It is tight under the fairing.
