Just bought a 2017 570eps for the wife, and sure enough she mentioned the heat coming from the right side. Now when your moving its not a big deal but sitting on it chatting to someone you feel it for sure. So took it down to a welder down the street and we took panel off and looked at it. Yeah the plastic panel has some shielding on it. But his real concern was the electronics for the carb. All that plastic and wire surely has to be absorbing a lot of heat. He had a heat thermometer and with it running close to 300 coming up from the pipe, muffler was about 200. So what he was thinking of is putting a little tab on the current heat shield in places and weld another shield on top, this would create another layer of air between and still allow air to move while you were moving. He did say that just by looking at the heat marks on the pipe that it gets extremely hot. Even a little electric fan was tossed around but you have to only run it while sitting still and motor running... going to try the double heat shield and get back on how it works out
