Well I finally got to do an extended ride in heat today. Rode for about an hour in varying conditions, highway, rural back roads and traffic . I got home and pulled out my trusty IR thermometer and took a quick reading on my exhaust. Reading around 200~230 f. The thermometer in my butt said it was much cooler. This is the result of a Special Ops under seat thermal blanket, ceramic coated header, open air box and race ecm. Not sure which had the greatest effect but it was in the low 90's today and I have to say I was as comfortable as one can be on an air cooled bike.
