Heat off of a big engine or header can be a real issue. I have had problems with both my Harley and the R3R. The R3R is not as bad as my Harley was with a D&D pipe on it. There was this big S bend in the back pipe to make it equal length that created a ton of heat. I moved over to an all stainless steel pipe and that helped.
Now, on the R3R I have not yet tackled the heat issue, but it is mostly the header even though that engine throws off a lot.
And for all the "Man up" guys out there, whether you are used to it or not, there is an issue of dehydration in extremely hot climates that no amount of "manning up" will fix if you aint careful.
One other note - Heat wrap - most people don't understand it properly. Heat wrap was originally designed to increase the heat within a header to create HP back in the day. Thus, it is hard to increase heat inside a pipe and not increase overall heat. When I had my Harley pipe wrapped it was still very hot. There was no appreciable decrease in heat.
However, if it was moved off to the shield itself and the shield spaced back a bit, it might absorb some of the heat.
Doesn't help that the stock air filter setup also vents heat up through the seat and out the sides.
