I'm not sure that blocking off everything would be a good idea. The heat has to get out somewhere, and I prefer it lower vs upper area. If my shins get too warm, I just put my feet on the outer part of the pegs where the air flow is very strong. Flipping your lower scoops to shoot air inward will help a bit too.
I also would be careful about blocking the lowers as it may cause other heat related problems like melting plastic. I had the heat shields on mine until a plastic gas filter I was using melted. Luckily I noticed it before it completly failed.
not sure about the totall route yet, just have a general idea of 4 or 5 stops we would like to make, the rest will be point and go.. should be great, can not wait, connie under me, and a v strom beside....
