Thanks for the info guys, looks like I got a little more work on mine. Stock motor with Rte pipe with turbo plug on it with .4mm of shims on the head button. I got 6.30 Minutes of run time to a tank. I ran a 25 min main with mine and the temps was 240. But I had a tire come off the rim an rub the dirt guard. I think that I will take a small shim out of the head.
