Since I switched over, I have not had a problem with the seal or over heated temps. When I looked at your choice of plugs from Dynamite, it did not look like a long bodied plug. You will be able to tell the difference in the seal when tightening the plug. I also noticed the color change at the tip of the plug, but that may just be me. I hope you find your solution.
On another note: If anyone is disatisfied with the carburator on the d3r, get the carb for the dx12 from Pro_Hobby and put it on the d3r......wow, it really does show performance gain. I replaced mine with the dx12 carb and use the air restrictor with it and it really gained some performance in tuning.
