The next fix will be new shocks. I was pricing them out and trying to decide between a new seat or new shocks first. Now that I softened up the stock shocks I think the stock seat can be saved for now. Probably just replace the shocks and leave the seat alone.
As far as the heat I just don't ride as much when it's too hot. I have an Arai full face that has amazing venting but still brutal when the sun is out. Night riding in the desert is one of my favorite things to do tho. I used to jump on my previous bikes when I couldn't sleep. Riding around at 1 a.m. and it's still over 95 outside is an enjoyable experience. The desert is a special thing in the early morning.
