I went for a short test ride and came back to take some temperature readings around the tank. left side of the bike has no issues and stays fairly cool. Right side or exhaust side gets a bit hotter. My temperature gun gives blank lines after 550 degrees and the exhaust where it comes out of the head gets hotter than that. I did the dirty deed of revving it up on the stand to put a simulated riding heat load on the exhaust side. the exhaust as it goes back cool as expected and hangs between 350 to 450 as it crosses under the tank. The hottest tank reading I was able to get was just under 200 degrees. The cylinder head surface temperature was about 220 at this point. The bottom of the radiator was coming in at 230 at this point and this is when I decided to drip a little water onto the radiators to cool it down then shut it off. The left side of the motor never saw more than 200 on the motor and the tank was reading at 125. I pointed my infrared gun into the tank and had a reading on top of 117. I still want to put a little bit of heat shield near the exhaust but as long as I keep fuel in this section, I think it will be ok. With out fuel in that section, that would be very dangerous.
