I used the general dimensions of the pattern posted earlier and cut the shapes out of a 200mm (8") black plastic plant pot. Only cost about $1.50 at our local hardware & sausage retailer. Cut them with bolt holes DOWN towards bottom of the pot / smaller diameter. Bolted on as usual with convex side out but they do need slightly longer bolts. They look like bought ones, match the black plastic parts on my 2012 650 beautifully. They do a great job of stopping wind funnelling up my chest & significantly reduce noise in the helmet. If you don't like the results / looks then buy another plant pot and start again. They only take about 10 minutes to make and can be cut with scissors.
As noted in an earlier post a big tank bag also stops a lot of this nuisance draft but I don't always want to carry that.
